RESUMO
This article presents dataset on agromorphogenic traits of Aloe vera treated by foliar application of Zn (zinc) and vermicompost. Data from yield and yield related characters with morphological traits were collected to assess the effect of vermicompost and Zn. The data showed in this dataset article contained 17 agronomic and morphological traits. The collected data were analyzed using excel, statistix 10.0 and STAR software. The analyzed data presented with the help of ANOVA (analysis of variance), mean comparison, correlation co-efficient and principal component analysis (PCA). Data of microclimate, correlation co-efficient and biplot distribution of principal components were presented graphically. The aim of the article is to ensure the data easily accessible and as a brief source of agricultural management information for crop development and production for researcher.
RESUMO
Plant-based beverages are increasing in popularity and quinoa is an attractive option. A hygienic implication linked to the production of beverages from raw material originating from plants is the high microbial contamination. The safety of the product can be guaranteed by lactic acid fermentation, and by using a probiotic strain as starter culture for the fermentation, the final product will benefit from a high number of live probiotics. In this study, a commercial probiotic strain was used for fermentation of a quinoa-based beverage. White quinoa grains were boiled, mixed with water and pasteurized before the beverage was fermented by Lactobacillus plantarum DSM 9843 at 30 °C for 2 days and then stored at 4 °C for 28 days. pH and production of D- and L-lactic acid were monitored, and viable counts were performed for total aerobes, Lactobacillus and Enterobacteriaceae. Colonies from countable plates were randomly picked and in total 335 isolates were identified by 16S rRNA gene sequencing. After heat treatment isolates of Enterobacter, Salmonella, Escherichia, Pantoea, Enterococcus, Klebsiella, and Leclercia were found in the heat-treated but unfermented quinoa beverage. After fermentation pH has decreased below 4, Enterobacteriaceae count was below detection limit and the Lactobacillus count was high 10.6 log CFU/ml (10.3-10.8) (p = 0.002 compared to inoculated counts). During storage pH and the concentration of lactic acid remained stable but after 28 days the lactobacilli count had decreased to 6.9 (6.6-7.2) (p = 0.065 compared to inoculated counts). The majority of isolates picked from Rogosa and Tryptic Soy Agar was identified as Lactobacillus plantarum but 19% and 6% were identified as Enterococcus mudtii and Pediococcus pentosaceous, respectively. The fermentation process applied improved the safety and stability of the product and fortified it with a high content of live probiotics. A safety problem is the spontaneous growth of enterococci (Enterococcus mudtii) during fermentation, enterococci originating from the native quinoa. A solution to this problem can be to increase the rate of the lactic acid fermentation, e.g. by using a higher inoculum of a more active starter culture, and/or to use a starter culture more antagonistic toward enterococci.
