Background: Brewer Ìs spent grain (BSG) is a biomass by-product generated in large volumes during industrial beer production. BSG has become a growing environmental problem, as most breweries discard it inappropriately, negatively impacting the environment. Alternatives for the exploitation of this by-product have consisted of elaborating food supplements for farm animals, obtaining biofuels, developing adsorbents, and obtaining substances for the food industry. However, the high moisture content in BSG (approximately 70%), poses a significant challenge in exploring various reuse alternatives. Therefore, the implementation of a pre-drying process becomes essential. Objective: This study aimed to analyze the BSG drying kinetics at different temperatures and the effect of the drying temperature on the physical properties and the content of bioactive compounds. Methods: BSG samples were dried at different temperatures (50, 60, 70, 80, 90, and 105°C) and analyzed for their moisture ratio, water activity, total polyphenol content (TPC), and DPPH (1,1-diphenyl-2-picrylhydrazil) radical scavenging activity. Also, four kinetics models were fitted to the drying data. Results:It was determined that the effective diffusivity was between 5.23x10
Antecedentes: El Bagazo residual de malta (BSG por sus siglas en inglés) es un subproducto biomásico generado en grandes volúmenes durante la producción industrial de cerveza. El BSG se ha convertido en un creciente problema para el medio ambiente, debido a que la mayoría de las cervecerías descartan inapropiadamente este residuo generando un impacto negativo al ambiente. Las alternativas para el aprovechamiento de este subproducto han consistido especialmente en la elaboración de suplementos alimenticios para animales de granja, obtención de biocombustibles, desarrollo de adsorbentes y obtención de productos para la industria alimentaria. Sin embargo, el alto contenido de humedad (~70%) del BSG representa un reto para el desarrollo de diferentes alternativas de reutilización, por lo que se hace necesario un proceso de secado previo. Objetivos: En este estudio se analizó la cinética de secado del BSG a diferentes temperaturas y el efecto de la temperatura de secado sobre sus propiedades físicas y contenido de compuestos bioactivos. Métodos: Las muestras de BSG fueron secadas a diferentes temperaturas (50, 60, 70, 80, 90 y 105°C) y analizadas en términos de razón de humedad, actividad acuosa, contenido de polifenoles totales (TPC) y actividad secuestradora del radical DPPH. Además, se ajustaron 4 modelos cinéticos a los datos de secado. Resultados: Se determinó que la difusividad efectiva del BSG varió entre 5.23x10

Abstract Non-invasive preimplantation genetic testing for aneuploidies (niPGT-A) aiming to assess cell-free embryonic DNA in spent culturemedia is promising, especially because it might overcome the diminished rates of implantation caused by the inadequate performance of trophectoderm (TE) biopsy. Our center is part of the largest study to date assessing the concordance between conventional PGT-A and niPGT-A, and we report here the delivery of the first baby born in Brazil using niPGT-A. The parents of the baby were admitted to our center in 2018. They did not present history of infertility, and they were interested in using in vitro fertilization (IVF) and PGT-A in order to avoid congenital anomalies in the offspring. A total of 11 (3 day-5 and 8 day-6) expanded blastocysts were biopsied, and the spent culture media (culture from day-4 to day-6) from 8 day-6 blastocysts were collected for niPGT-A. Overall, 7 embryos yielded informative results for trophectoderm (TE) and media samples. Among the embryos with informative results, 5 presented concordant diagnosis between conventional PGTA and niPGT-A, and 2 presented discordant diagnosis (1 false-positive and one falsenegative). The Blastocyst 4, diagnosed as 46, XY by both niPGT-A and conventional PGTA, was warmed up and transferred, resulting in the birth of a healthy 3.8 kg boy in February 2020. Based on our results and the recent literature, we believe that the safest current application of niPGT-A would be as a method of embryo selection for patients without an indication for conventional PGT-A. The approximate 80% of reliability of niPGT-A in the diagnosis of ploidy is superior to predictions provided by other noninvasive approaches like morphology and morphokinetics selection.
Resumo Abordagens para o teste genético pré-implantacional não-invasivo para aneuploidias (non-invasive preimplantation genetic testing for aneuploidies, niPGT-A, em inglês) com o objetivo de avaliar o DNA embrionário livre são promissoras, especialmente porque estas podem reverter as menores taxas de implantação causadas por inadequada biópsia de trofectoderma (TE). Nesse contexto, nosso centro é parte do maior estudo atual que avalia as taxas de concordância entre PGT-A convencional e niPGT-A, e relatamos aqui o nascimento do primeiro bebê brasileiro após niPGT-A. Os pais do bebê foram admitidos no nosso centro em 2018. Eles não apresentavam histórico de infertilidade, e estavam interessados em utilizar os tratamentos de fertilização in vitro (FIV) e PGT-A para evitar anomalias congênitas na progênie.Umtotal de 11 blastocistos expandidos (3 do dia-5 e 8 do dia-6) foram submetidos a biópsia, e os meios de cultivo condicionados (cultivo do dia-4 ao dia-6) de 8 blastocistos do dia-6 foram coletados para niPGT-A. No total, resultados informativos para as amostras de TE e dos meios foram obtidos para sete embriões. Entre os embriões com resultado informativo, 5 apresentaram diagnóstico concordante entre PGT-A convencional e niPGT-A, e 2 apresentaram diagnóstico discordante (1 falso positivo e 1 falso negativo). O Blastocisto 4, diagnosticado como 46, XY por ambos niPGT-A e PGT-A convencional, foi desvitrificado e transferido, o que resultou no nascimento de ummenino saudável, que pesava 3,8 kg, em fevereiro de 2020. Com base em nossos resultados e literatura contemporânea, acreditamos que a aplicação atualmais segura do niPGT-A seria como método de seleção embrionária para pacientes sem indicação ao PGT-A convencional. A confiabilidade aproximada de 80% do niPGT-A para determinação da ploidia ainda é superior àquela obtida com abordagens não invasivas, como seleção morfológica ou morfocinética.

Resumo O estudo tem como objetivo explorar as ocorrências fiscais dos municípios brasileiros no período 2002 a 2016, analisando a relação entre as receitas, as despesas com pessoal, os estratos de tamanho, os delineamentos da atividade econômica e as riquezas municipais, considerando momentos de contração e de expansão do produto nacional. O procedimento metodológico consistiu na utilização de uma representação de dados em painel, com a aplicação do teste de especificação de Hausman, em que o modelo de efeito fixo, em confronto com o de efeitos aleatórios, se mostrou mais adequado para apuração da relação da variável dependente e das independentes. O cálculo do Quociente do Resultado de Execução Financeira (QREF) mensurou a situação fiscal das unidades federadas e aferiu as relações do QREF com outras variáveis, tais como o perfil de arrecadação, o balanço econômico municipal, a riqueza econômica da localidade, a despesa com pessoal e o tamanho populacional. As repercussões revelaram que as elevadas despesas com pessoal impactam negativamente as apurações dos resultados fiscais, enquanto que, os melhores cômputos do QREF ocorreram em unidades nas quais foram detectados os maiores indicadores de produto interno bruto per capita. Quanto ao nível de atividade econômica, a preponderância financeira dos setores agrícola e de serviços, revelou melhores condições pecuniárias, ressalvando que nos municípios com perfil industrial e classificados como pequenos foram detectados os piores resultados. No desfecho, a crise econômica de 2009 derivou em resultados fiscais ruins, enquanto que a crise política/econômica de 2015 e 2016 transcorreu com respostas orçamentárias mais apropriadas.
Resumen Este estudio tiene como objetivo explorar los sucesos fiscales de los municipios brasileños en el período 2002 a 2016, analizando la relación entre ingresos, gastos de personal, estratos de tamaño, delineamientos de la actividad económica y riqueza municipal, considerando momentos de contracción y de expansión del producto nacional. El procedimiento metodológico consistió en utilizar una representación de datos en panel, con la aplicación de la prueba de especificación de Hausman, en la que el modelo de efectos fijos, en comparación con el modelo de efectos aleatorios, resultó ser más adecuado para determinar la relación variable dependiente e independiente. El cálculo del índice de resultados de ejecución financiera (QREF) midió la situación fiscal de las unidades federadas y calculó la relación del QREF con otras variables, como el perfil de recaudación, el balance económico municipal, la riqueza económica del municipio, el gasto en personal y el tamaño de la población. Los resultados mostraron que los elevados gastos en personal tienen un impacto negativo en los resultados fiscales, mientras que los mejores cómputos del QREF ocurrieron en unidades donde se detectaron los indicadores más altos del producto interno bruto per cápita. En cuanto al nivel de actividad económica, la preponderancia financiera de los sectores agrícola y de servicios reveló mejores condiciones pecuniarias, destacando que los peores resultados se encontraron en municipios con perfil industrial y clasificados como pequeños. Al final, la crisis económica de 2009 dio lugar a malos resultados fiscales, mientras que la crisis político-económica de 2015 y 2016 transcurrió con respuestas presupuestarias más apropiadas.
Abstract The study explores the fiscal events of Brazilian municipalities in the period 2002 to 2016, analyzing the relationship between revenues, personnel expenses, size strata, delineations of economic activity, and municipal wealth, considering moments of contraction and national product expansion. The methodology used panel data, with the application of the Hausman specification test, in which the fixed-effect model, in comparison with the random-effects model, proved to be more suitable for determining the variable relationship dependent and independent. The calculation of the Quotient of the Financial Execution Outcome (QFEO) measured the fiscal situation of the federated units. It measured the relationship of the QFEO with other variables, such as the collection profile, the municipal economic activity, the municipality's economic wealth, the expenditure on personal, and the population size. The s results showed that higher personnel expenses negatively impact tax investigations. The best calculations in the QFEO occurred in units where the highest gross domestic product indicators were detected per capita. As for the level of economic activity, the financial preponderance of the agricultural and service sectors revealed better pecuniary conditions. The worst results were found in municipalities with an industrial profile and classified as small. The economic crisis of 2009 resulted in poor fiscal results, while the political/economic crisis of 2015 and 2016 had more appropriate budget responses.

MATERIALES Y MÉTODOS: La borra de café, un subproducto obtenido en establecimientos especializados en la preparación de café soluble a base de grano, se diluyo en tampón fosfato salino y se mezcló en proporciones iguales con las muestras de semen de 16 voluntarios aparentemente sanos. A cada muestra se le determinó el efecto sobre la movilidad espermática en función del tiempo (30, 60, 90 y 120 minutos, n=16) y sobre los parámetros funcionales (n=6) por medio de citometría de flujo: potencial de membrana mitocondrial, producción de especies reactivas de oxígeno y lipoperoxidación de la membrana espermática. RESULTADOS: La incubación de los espermatozoides con la borra de café evidencio un cambio positivo en la movilidad espermática. Adicionalmente, la incubación con la borra de café incremento significativamente el potencial de membrana mitocondrial en los espermatozoides. CONCLUSIÓN: La borra de café, seguramente debido a los compuestos antioxidantes, afecta positivamente la movilidad espermática aumentando el potencial de membrana mitocondrial. Por lo tanto, esto es un paso inicial en la búsqueda de un suplemento de origen natural que aumente la calidad seminal.
OBJECTIVE: The objective of this work is to establish the effect of spent coffee grounds on the motility and functional parameters of human spermatozoa, in vitro. MATERIALS AND METHODS: Spent coffee grounds, a by-product obtained in specialized establishments in the preparation of soluble coffee based on grain, was diluted in saline phosphate buffer and mixed in equal proportions with semen samples from 16 apparently healthy volunteers. Each sample was determined the effect on sperm motility as a function of time (30, 60, 90 and 120 minutes, n=16) and on functional parameters (n=6) by means of flow cytometry: mitochondrial membrane potential, reactive oxygen species production and membrane lipoperoxidation. RESULTS: The incubation of the spermatozoa with the spent coffee grounds showed a positive change in sperm motility. Additionally, incubation with spent coffee grounds significantly increased the mitochondrial membrane potential in human sperm cells. CONCLUSION: Spent coffee grounds, probably due to antioxidant compounds, positively affects sperm motility by increasing mitochondrial membrane potential. Therefore, this is an initial step in the search for a supplement of natural origin that increases seminal quality.

Spent coffee ground (SCG) is the waste generated during the preparation of instant coffee and is the sourceof industrially valuable organic compounds. In this article, SCG was pretreated by roasting at 150°C for 30minutes and heated with water at 90°C for extracting carbohydrates and phenolic compounds, after which1.0% (w/w) β-mannanase was applied for the hydrolysis of pretreated SCG. SCG is characterized in terms ofits total sugar content by the anthrone–sulfuric assay and phenolic compounds by Folin−Ciocalteu’s procedure.In this study, the total sugar increased by 14.79% (w/w) by the roasting process, and subsequently enzymatichydrolysis increased the total sugar yield up to 17.43% (w/w) compared to the untreated SCG, i.e., 10.24%(w/w). The reducing sugar was estimated by the dinitrosalicylic acid method and the end product increased to106.10 (mg Glucose/g) from the initial content 5.32 (mg Glucose/g raw SCG). The total phenolic compoundincreased to 291.86 (mg Gallic acid/g lyophilized material), which was a 6.39-fold increase compared to thenative SCG (45.68 mg Gallic acid/g). These results point to the valuable compounds present in SCG, can beenhanced by combining the roasting pretreatment and enzymatic hydrolysis, and can be utilized in the foodand biotech industries.

Spent nuclear fuel (SNF) pool is an essential unit of a nuclear power plant infrastructure, where radioactive fuel rods arekept for cooling and shielding, before reprocessing. This study explored the presence of bacteria in SNF pool water withemphasis on their capability to form biofilms on pool wall cladding material stainless steel (SS-304L). Bacteria wereisolated from SNF pool water and were characterized using 16S rRNA gene sequencing. The six bacterial isolates (Bacillussubtilis, Staphylococcus sps., S. arlettae, S. epidermidis, S. auricularis and Chryseobacterium gleum) can grow and formbiofilms at very low nutrient condition as well as in chronic radioactivity. The bacterial isolates formed biofilm on SS-304Land glass. However, the biofilm parameters assessed by CLSM microscopy showed that the strains preferred SS-304Lsurface for biofilm formation. On SS-304L, the maximum biomass (0.45 lm3/lm2) was formed by S. arlettae whencompared to maximum biomass (0.054 lm3/lm2) by Staphylococcus sp., on glass. Maximum biofilm thickness on SS304L was observed by Staphylococcus sp. (8.81 lm) when compared to that of S. epidermidis (4.16 lm) on the glasssurface. The biofilm formation on SS-304L surface suggests the possible risk of microbial-induced corrosion of SNF poolcladding material. This study highlights the need for mandatory monitoring of microbial biofilm formation in an extremeenvironment such as SNF pool.

ABSTRACT Background: Inherent differences in organization of stroke care and rehabilitation practices in various settings influence the activity levels of patients in the hospital. The majority of published studies have been carried out in developed countries such as the United States, United Kingdom, Australia, Switzerland and Belgium; however, data from developing countries are scarce. Objective: To measure the amount and nature of physical activity of patients admitted to medical wards of Indian hospitals and to assess the association between family presence and the patient and between the patient’s functional status and their physical activity level. Method: This is an observational behavioral mapping study. A trained physical therapist recorded the patients’ (N=47) physical activity level through direct observation in the ward using a predetermined observation scheme. Results: Participants were found inactive and alone for 19% (inter quartile range [IQR] 12-36%) and 15% (IQR 10-19%) of the time during the day, respectively. They spent 46% (IQR 31-55%) of the time in therapeutic activities and 31% (IQR 22-34%) of the time in non-therapeutic activities. The family was present with patients 50% of the time during the day. Family presence with the patient and the patient’s moderate dependence in daily activities are positively associated with their activity levels. Conclusion: Patients with stroke admitted to Indian hospitals spent less time being inactive and alone and more time with family participating in therapeutic activities. The presence of family members with the patients during hospital stay may be a significant resource for encouraging patients to be more active.

In recent decades, increasing interest has been devoted to xylanolytic enzymes due to their potential use in many industrial processes. This study describes the production of xylanase, -xylosidase and -Larabinofuranosidase, belonging to the xylanolytic complex, by Penicillium janczewskii using brewer's spent grain as substrate for solid-state fermentation. The optimized conditions for high levels of xylanase, -xylosidase and -Larabinofuranosidase production were: 50% initial moisture, which was provided by Vogel's salt solution, seven days of cultivation at 20-30 °C. Fermentation enriched the bioproduct with some amino acids and did not add mycotoxins to it. The use of brewer's spent grain as substrate for fungal cultivation and enzyme production can both add value to this waste and reduce the production cost of xylanolytic enzymes.
Nas últimas décadas, há interesse crescente nas enzimas xilanolíticas devido à sua potencial utilização em muitos processos industriais. Este estudo descreve a produção de xilanase, -xilosidase e -Larabinofuranosidase, três enzimas do complexo xilanolítico, por Penicillium janczewski utilizando bagaço de cevada como substrato para fermentação em estado sólido. As condições selecionadas para a produção de elevados níveis de xilanase, - xilosidase e -L-arabinofuranosidase por esta linhagem fúngica foram 50% de umidade inicial, sendo esta fornecida por uma solução de sais de Vogel e cultivo por sete dias a 20-30 °C. O bioproduto fermentado foi enriquecido com alguns aminoácidos e se apresentou livre de micotoxinas. O uso do bagaço de cerveja como substrato para o cultivo de fungos e produção de enzimas não só pode agregar valor a esses resíduos, mas também reduzir o custo de produção de enzimas xilanolíticas.

Poultry by-products are great economic sources that need to be exploited. Poultry skin could be utilized to extract protein particularly elastin, which is often incorporated in the production of functional food, cosmetic industry or medicine due to its antioxidative properties. In this study, water-soluble elastin was successfully extracted from broiler and spent hen skin and analysed for antioxidant activities including DPPH (1,1-diphenyl-2-picryl hydrazyl), ABTS and metal chelating activity. Antioxidant activity of elastin extracted from broiler skin hydrolysed by Alcalase (EBA) and Elastase (EBE) also elastin extracted from spent hen skin hydrolyzed by Alcalase (ESA) and Elastease (ESE). The EBE, EBA, ESE and ESA had higher DPPH (16-30, 19-35, 29-48 and 31-50%, respectively), ABTS activity ( 73-79, 60-79, 67-79 and 72-79 %, respectively), and Fe2+ chelating activity ( 65-69, 50-56, 71-77 and 62-70 %, respectively). This concluded that water-soluble elastin is a bioactive component that could potentially be used in the formulation of functional foods, nutraceuticals, cosmetic and pharmaceutical industry.

Culture filtrates of six different edible mushroom species were screened for antimicrobial activity against tomato wilt bacteria Ralstonia solanacearum B3. Hericium erinaceus, Lentinula edodes (Sanjo 701), Grifola frondosa, and Hypsizygus marmoreus showed antibacterial activity against the bacteria. Water, n-butanol, and ethyl acetate extracts of spent mushroom substrate (SMS) of H. erinaceus exhibited high antibacterial activity against different phytopathogenic bacteria: Pectobacterium carotovorum subsp. carotovorum, Agrobacterium tumefaciens, R. solanacearum, Xanthomonas oryzae pv. oryzae, X. campestris pv. campestris, X. axonopodis pv. vesicatoria, X. axonopodis pv. citiri, and X. axonopodis pv. glycine. Quantitative real-time PCR revealed that water extracts of SMS (WESMS) of H. erinaceus induced expressions of plant defense genes encoding beta-1,3-glucanase (GluA) and pathogenesis-related protein-1a (PR-1a), associated with systemic acquired resistance. Furthermore, WESMS also suppressed tomato wilt disease caused by R. solanacearum by 85% in seedlings and promoted growth (height, leaf number, and fresh weight of the root and shoot) of tomato plants. These findings suggest the WESMS of H. erinaceus has the potential to suppress bacterial wilt disease of tomato through multiple effects including antibacterial activity, plant growth promotion, and defense gene induction.

Introducción: Coffea arabica L., además de su importancia comercial, también se considera una planta medicinal, porque presenta propiedades biológicas diversas, pero por su comercialización como bebida genera muchos subproductos. La borra es uno de estos, que se obtiene por la preparación de la bebida, contiene una concentración significativa de compuestos polifenólicos y, por tanto, la recuperación de estas sustancias a partir de un residuo sin valor, sería potencialmente útil para la industria farmacéutica y alimentaria. Objetivos: recuperar compuestos fenólicos a partir de la borra de café y darle un valor agregado a un residuo de origen vegetal, como fuente de componentes con capacidad antirradicales libres in vitro. Métodos: la borra de café previamente secada se sometió a extracciones sólido-líquido usando diferentes sistemas de solventes. Se evaluaron las propiedades antioxidantes in vitro usando los métodos del catión radical del ácido 2,2´-azino-bis (3-etilbenzotiazoline-6-sulfónico) y del radical 1,1-difenil-2-picrilhidracilo. Se usó cromatografía líquida de alta resolución acoplada a espectrometría de masas para la caracterizaron de los principales componentes. Resultados: todos los extractos obtenidos mostraron buena capacidad antioxidante, con el extracto de etanol:agua como el mejor, seguido del extracto de metanol acidulado. Sin embargo, la capacidad antioxidante de la fracción en diclorometano del extracto etanol:agua resultó menor que la presentada por la taza de café. Se identificaron los ácidos clorogénico, isoclorogénico y feruloilquínico como los principales componentes de la borra de café. Conclusiones: todos los extractos presentaron buena capacidad protectora contra radicales libres. La borra de café, considerada un desecho obtenido del procesamiento industrial, se puede convertir en materia prima para la recuperación de sustancias antioxidantes; lo cual genera grandes expectativas sobre su posible uso en la industria farmacéutica y alimentaria, y le da al café un valor agregado importante.
Introduction: besides its commercial importance, Coffee arabica L. is also considered a medicinal plant due to its various biological properties, but its marketing produces a large amount of residues. Spent coffee grounds are one of these residues, which are obtained after the preparation of the drink and contain a significant concentration of polyphenolic compounds. Therefore, the recovery of these substances costless residual will be potentially useful for food and pharmaceutical industry. Objectives: to recover polyphenolic compounds from spent coffee grounds and to give an added value to a vegetable waste as a source of substances with free radicals capacity in vitro. Methods: dehydrated spent coffee grounds were subjected to solid-liquid extraction using different solvent systems. Antioxidant properties were evaluated in vitro using the radical monocation 2,2´-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and the stable free radical 2-2-diphenyl-1-picrylhydrazyl (DPPH). Liquid chromatography coupled to mass spectrometry was applied to characterize the main compounds. Results: all the extracts obtained showed a good antioxidant capacity with ethanol-water extract, followed by acidulated methanol extract. However, the antioxidant capacity of the ethanol-water extract was lower than coffee beverage. Chlorogenic, isochlorogenic and feruloylquinic acids were identified as the main compounds present in spent coffee grounds. Conclusions: all extracts showed a significant protection effect against free radicals; spent coffee ground, which is considered an undesirable solid waste from industrial processing, could be an add-value raw material in the recovery of antioxidant substances which generates great expectations about its possible use in the pharmaceutical and food industry and gives coffee an important added value.

This study was conducted in order to perform efficient extraction of lignocellulolytic enzymes amylase (EC 3.2.1.1), cellulase (EC 3.2.1.4), laccase (EC 1.10.3.2), and xylanase (EC 3.2.1.8) from spent mushroom compost (SMC) of Pleurotus ostreatus, P. eryngii, and P. cornucopiae. Optimal enzyme recovery was achieved when SMCs were extracted with 50 mM sodium citrate (pH 4.5) buffer at 4degrees C for 2 hr. Amylase, cellulase, and xylanase activities showed high values in extracts from P. ostreatus SMC, with 2.97 U/g, 1.67 U/g, and 91.56 U/g, respectively, whereas laccase activity and filter paper degradation ability were highest in extracts from P. eryngii SMC, with values of 9.01 U/g and 0.21 U/g, respectively. Enzymatic activities varied according to the SMCs released from different mushroom farms. The synthetic dyes remazol brilliant blue R and Congo red were decolorized completely by the SMC extract of P. eryngii within 120 min, and the decolorization ability of the extract was comparable to that of 0.3 U of commercial laccase. In addition, laccase activity of the SMC extract from P. eryngii was compared to that of commercial enzymes or its industrial application in decolorization.

Este estudo teve como objetivo avaliar o potencial de utilização da carne de ovinos de descarte na elaboração de mortadelas. Três formulações de mortadela foram desenvolvidas, com 90, 80 e 70% de carne ovina, adicionadas de 10, 20 e 30% de gordura suína. Os resultados demonstraram que as três formulações de mortadela atenderam aos parâmetros microbiológicos preconizados pela legislação brasileira, sendo, portanto, seguros para o consumo humano. Para os parâmetros cinzas, amido, cloretos, pH e atividade de água não houve diferença estatística entre as formulações (P>0,05). Os valores obtidos na análise de umidade diferiram estatisticamente entre os tratamentos (P<0,05), aumentando os valores médios, à medida que foram aumentados os percentuais de carne adicionados, ficando a formulação com 90% de carne fora dos padrões recomendados pela legislação brasileira. A mortadela elaborada com 90% de carne obteve maiores percentuais nas análises de estabilidade de emulsão e capacidade de retenção de água. A formulação elaborada com 90% de carne se diferenciou das demais estatisticamente na análise sensorial, sendo a ela atribuídos escores menores para os atributos de textura e avaliação global. Na avaliação da intenção de compra, os avaliadores comentaram que comprariam os produtos independente das formulações. Os resultados demonstram que a carne de ovinos de descarte é uma opção viável na elaboração de mortadela, uma vez que resulta em produtos com elevado grau de aceitação e qualidade nutricional, agregando valor aos cortes de ovinos.
The aim of this study was to evaluate the potential use of spent lamb meat in the preparation of mortadella. Three formulations of mortadella were developed, using 90, 80 and 70% of lamb meat, each with 10, 20 and 30% of pork fat, respectively. The results showed that the proposed formulations met the microbiological parameters recommended by the Brazilian legislation, being, therefore, a safe meat product for human consumption. The parameters of ashes, starch, sodium chloride, pH and water activity showed no significant difference among the formulations (P>0.05). The moisture contents differed significantly from one sample to the other (P<0.05). An increase in the amount of lamb meat in the mortadella formulation resulted in an increase in moisture; this made the formulation with 90% meat improper, according to the standards recommended by the Brazilian legislation. The mortadella with 90 % meat had the highest percentages of emulsion stability and water holding capacity. The sensory evaluation showed that the formulation with 90% lamb meat presented the lowest scores of texture and overall acceptance. However, the evaluators commented that they would buy any of the products regardless of the formulation. The results show that the use of spent lamb meat is a viable option for the preparation of mortadella, as the resulting products have been widely accepted. In addition, it also gives spent lamb carcasses more commercial value.

Spent substrate, the residual material of mushroom cultivation, causes disposal problems for cultivators. Currently the spent substrate of different mushrooms is used mainly for composting. Edible mushrooms of Pleurotus sp. can grow on a wide range of lignocellulosic substrates. In the present study, Pleurotus eous was grown on paddy straw and the spent substrate was used for the production of ethanol. Lignocellulosic biomass cannot be saccharified by enzymes to high yield of ethanol without pretreatment. The root cause for the recalcitrance of lignocellulosic biomass such as paddy straw is the presence of lignin and hemicelluloses on the surface of cellulose. They form a barrier and prevent cellulase from accessing the cellulose in the substrate. In the untreated paddy straw, the amount of hemicelluloses and lignin (in % dry weight) were 20.30 and 20.34 respectively and the total reducing sugar was estimated to be 5.40 mg/g. Extracellular xylanase and ligninases of P. eous could reduce the amount of hemicelluloses and lignin to 16 and 11(% dry weight) respectively, by 21st day of cultivation. Growth of mushroom brought a seven fold increase in the total reducing sugar yield (39.20 mg/g) and six fold increase in the production of ethanol (6.48 g/L) after 48hrs of fermentation, when compared to untreated paddy straw.
