[Perception of Public Health Nurses on Health Foods and Utilization of Health Food Informationduring Specific Health Guidance].

This study aimed to investigate the awareness of public health nurses (PHNs) regarding health foods and the actual utilization of health food-related information in specific health guidance. A questionnaire survey among PHNs working in municipalities in Kagoshima Prefecture (n=170, response rate; 41.5%) was conducted in September 2022. As a result, 39.4% of the PHNs had experience using health foods, and 43.5% consulted about health food from local residents. Major topics of consultation included effectiveness (78.4%) and drug interactions (35.1%). Approximately 10.2% of the PHNs always confirm the use of health food during specific health guidance, while 41.6% did not ever check. Additionally, 36.3% of the PHN were aware of the obligation to report adverse events caused by health foods to the prefectural governments and Ministry of Health, Labor, and Welfare. The present study showed that recognition and intelligibility on health foods varied among PHNs. Therefore, knowledge acquisition on safety and efficacy is needed for proper use of health foods.

Long-term CMV monitoring and chronic rejection in renal transplant recipients.

Introduction: Cytomegalovirus (CMV) is well established to be an independent risk factor for graft loss after kidney transplantation (KTx). Monitoring for CMV in the chronic phase is not defined in the current guideline. The effects of CMV infection, including asymptomatic CMV viremia, in the chronic phase are unclear. Methods: We performed a single-center retrospective study to investigate incidence of CMV infection in the chronic phase, defined as more than 1 year after KTx. We included 205 patients who received KTx between April 2004 and December 2017. The CMV pp65 antigenemia assays to detect CMV viremia were continuously performed every 1-3 months. Results: The median duration of the follow-up was 80.6 (13.1-172.1) months. Asymptomatic CMV infection and CMV disease were observed in 30.7% and 2.9% in the chronic phase, respectively. We found that 10-20% of patients had CMV infections in each year after KTx which did not change over 10 years. The history of CMV infection in the early phase (within 1 year after KTx) and chronic rejection were significantly associated with CMV viremia in the chronic phase. CMV viremia in the chronic phase was significantly associated with graft loss. Discussion: This is the first study to examine the incidence of CMV viremia for 10 years post KTx. Preventing latent CMV infection may decrease chronic rejection and graft loss after KTx.

Acquisition of Antibody Against Cytomegalovirus After Kidney Transplantation in Seronegative Recipients.

BACKGROUND: Cytomegalovirus (CMV) infection is one of the most important infectious diseases affecting recipients of kidney transplantation (KTx). However, the timing of seroconversion for CMV infection in seronegative recipients remains unclear. We evaluated CMV infections in CMV-seronegative recipients and the time to acquire antibodies against CMV. METHODS: We conducted a retrospective study of 228 recipients who underwent KTx between March 1988 and February 2018 at the Niigata University Hospital. The anti-CMV IgG antibody profile before and after transplantation was analyzed. Oral acyclovir or valganciclovir was used as prophylactic therapy for at least 6 months after transplantation. Cytomegalovirus infection was defined as CMV viremia detected using the CMV pp65 antigenemia assay. RESULTS: In this study, 50 cases (21.9%) were CMV-seronegative recipients. Over a median follow-up period of 126.7 months, 68% (34/50) of CMV-seronegative recipients experienced CMV viremia or overt disease symptoms as the first episode of CMV infection. The median duration from transplant to CMV infection was 69.0 days (range, 22-7426). All the recipients who experienced CMV infections acquired seroconversion. The median duration from KTx to seroconversion was 7.2 months (range, 2.8-252.3). Almost all CMV-seronegative recipients could acquire anti-CMV IgG antibodies within 2.5 years. In seronegative recipients whose donors were seronegative, no CMV viremia was found, and none developed anti-CMV IgG antibodies. CONCLUSIONS: In the clinical practice of CMV-seronegative recipients, we should consider that physicians must closely monitor the occurrence of CMV infection up until 2.5 years after KTx.

Pretransplant BMI Should Be <25 in Japanese Kidney Transplant Recipients: A Single-Center Experience.

BACKGROUND: The aim of this study was to determine the appropriate body mass index (BMI) in Japanese kidney transplant (KTx) recipients. We analyzed the effects of pre- and post-transplant (Tx) obesity on graft and patient survival, perioperative complications, post-transplant diabetes mellitus (PTDM), and cardiovascular disease (CVD) in Japanese KTx recipients. METHODS: This retrospective study included 269 recipients who underwent KTx from 2008 through 2020 at Niigata University Hospital. Obesity was defined as a body mass index (BMI) ≥25 kg/m2. We examined the association between pre- and post-Tx obesity and graft survival, patient survival, the incidence of PTDM and CVD, and perioperative surgical complications. RESULTS: The graft survival rate was lower in the pre-Tx BMI ≥25 kg/m2 group, although there was no significant difference in patient survival. There was no difference in graft and patient survival between the post-Tx BMI ≥25 kg/m2 group and the <25 kg/m2 group. A pre-Tx BMI ≥25 kg/m2 was an independent risk factor for biopsy-proven allograft rejection. New-onset DM after transplantation was significantly more common in the BMI ≥25 kg/m2 group than in the BMI <25 kg/m2 group (36% vs 13%; P = .002). The incidence of CVD was significantly higher in the post-Tx BMI ≥30 kg/m2 group than in the BMI <30 kg/m2 group (50% vs 11%; P = .023). There were no differences in surgical operating time, intraoperative blood loss, or perioperative complications between the obese and non-obese groups. CONCLUSION: Pre-Tx BMI ≥25 kg/m2 may be a risk factor for allograft rejection and graft loss. Post-Tx BMI should be <25 kg/m2 to reduce the risk for PTDM.

Inhibition of retinoid X receptor improved the morphology, localization of desmosomal proteins and paracellular permeability in three-dimensional cultures of mouse keratinocytes.

Retinoic acid (RA) plays an important role in epithelial homeostasis and influences the morphology, proliferation, differentiation and permeability of epithelial cells. Mouse keratinocytes, K38, reconstituted non-keratinized stratified epithelium in three-dimensional (3D) cultures with serum, which contains retinol (a source of RA), but the morphology was different from in vivo epithelium. The formed epithelium was thick, with loosened cell-cell contacts. Here, we investigated whether the inhibition of RA receptor (RAR)/retinoid X receptor (RXR)-mediated signaling by an RXR antagonist, HX 531, improved K38 3D cultures in terms of morphology and intercellular junctions. The epithelium formed by 0.5 µM HX531 was thin, and the intercellular space was narrowed because of the restoration of the layer-specific distribution of desmoglein (DSG)-1, DSG3 and plakoglobin (PG). Moreover, the levels of desmosomal proteins and tight junction proteins, including DSG1, DSG2, DSG3, PG, claudin (CLDN)-1 and CLDN4 increased, but the adherens junction protein, E-cadherin, did not show any change. Furthermore, CLDN1 was recruited to occludin-positive cell-cell contacts in the superficial cells and transepithelial electrical resistance was increased. Therefore, K38 3D cultures treated with 0.5 µM HX531 provides a useful in vitro model to study intercellular junctions in the non-keratinized epithelium.

Empirical study of the 30-s chair-stand test as an indicator for musculoskeletal disorder risk of sedentary behaviour in Japanese office workers: a cross-sectional empirical study.

OBJECTIVES: Sedentary behaviour among office workers and the risk of adverse health outcomes are public health problems. However, risk indicators for these outcomes require invasive biochemical examination. A proactive screening tool using a non-invasive, easy-to-use method is required to assess the risk focused on musculoskeletal health for primary prevention. However, middle-aged adults have insufficient awareness of musculoskeletal disorders. This study examined to determine whether the 30-s chair-stand test (CS-30) can be used as a proactive screening index for musculoskeletal disorder risk of sedentary behaviour in office workers. DESIGN: Cross-sectional study using self-administered questionnaires and physical measurements. SETTING: Four workplaces located in a metropolitan area of Japan. PARTICIPANTS: 431 Japanese office workers aged 20-64 years. 406 valid sets of results remained (valid response rate: 94.2%). PRIMARY AND SECONDARY OUTCOME MEASURES: Musculoskeletal function was measured using the CS-30, quadriceps muscle strength. Receiver operating characteristic curve analysis was used to determine the sensitivity, specificity and optimal cut-off value for the CS-30. The risk of future incidence of musculoskeletal disorders was calculated using current quadriceps muscle strength. RESULTS: In total participants, 47.0% were male and the mean sitting time in work duration was 455.6 min/day (SD=111.2 min). The mean lower limb quadriceps muscle strength was 444.8 N (SD=131.3 N). For the optimum cut-off value of 23 on the CS-30 for all participants, sensitivity was 0.809 and specificity was 0.231. For men, the optimum cut-off was 25, with a sensitivity of 0.855 and a specificity 0.172. For women, the optimum cut-off was 21, with a sensitivity of 0.854 and a specificity 0.275. CONCLUSIONS: Sensitivity was high, but specificity was insufficient. The CS-30 may be a potential proactive screening index for musculoskeletal disorder risk of sedentary behaviour, in combination with other indicators.

Analysis of the prevalence of systemic de novo thrombotic microangiopathy after ABO-incompatible kidney transplantation and the associated risk factors.

OBJECTIVES: To analyze the prevalence of systemic de novo thrombotic microangiopathy in ABO-incompatible kidney transplantation and risk factors associated with this condition. METHODS: A total of 201 patients who received living-donor kidney transplantation (114 patients with ABO-identical kidney transplantation and 87 patients with ABO-incompatible kidney transplantation) were retrospectively analyzed. Systemic de novo thrombotic microangiopathy was diagnosed clinically according to the presence of thrombocytopenia with microangiopathic hemolytic anemia and pathological findings of thrombotic microangiopathy. Anti-A and anti-B antibodies were purified from human plasma, and these antibodies' bindings to human kidney were investigated in vitro. RESULTS: ABO-incompatible kidney transplantation was a significant risk factor of systemic de novo thrombotic microangiopathy (odds ratio 55.9, 95% CI 1.8-8.9, P < 0.001) after transplantation. Multivariate logistic regression analysis showed that non-use of mycophenolate mofetil, pretreatment immunoglobulin G antibody titer ≥64-fold and pretransplant immunoglobulin M antibody titer ≥16-fold were significant risk factors for systemic de novo thrombotic microangiopathy in ABO-incompatible kidney transplantation. Microvascular inflammation of 1-h post-transplant biopsy could be observed more frequently in thrombotic microangiopathy patients than in non-thrombotic microangiopathy patients. Anti-A and anti-B antibodies purified from human plasma showed a strong in vitro reaction against human kidney when the antibody titer was ≥16-fold. CONCLUSIONS: Antibody titer should be decreased to ≤16-fold until the day of ABO-incompatible kidney transplantation by desensitization therapy including mycophenolate mofetil. The 1-h biopsy results might help to diagnose systemic de novo thrombotic microangiopathy.

[RESULTS OF TONSILLECTOMY AND STEROID PULSE THERAPY IN 20 CASES OF RECURRENT IgA NEPHROPATHY AFTER KIDNEY TRANSPLANTATION].

(Background) The standard treatment for recurrent immunoglobulin A nephropathy (rIgAN) after kidney transplantation (KTx) has not been established. (Methods) The results of treatment consisting of tonsillectomy and steroid pulse therapy in 20 recipients who were diagnosed as rIgAN were retrospectively analyzed. (Results) The level of proteinuria significantly decreased from 0.84±0.81 g/day to 0.27±0.31 g/day after treatment (P=0.007). Microscopic hematuria disappeared or improved in 58.3% and 66.6% of recipients 6 and 12 months after treatment, respectively. Serum creatinine levels remained stable for 5 years by the treatment, except for 3 cases of graft loss. Sixteen recipients received renal graft biopsies before and after treatment. Mesangial IgA deposition were dramatically decreased in 7 recipients (43.75%). The degree of mesangial hypercellularity, endocapillary hypercellularity, and crescents formation improved in 3 (18.8%), 6 (37.5%), and 4 (25%) recipients after treatment. (Conclusion) Steroid pulse therapy combined with tonsillectomy may be clinically and histopathologically effective treatment for rIgAN after KTx.

[SMALL CELL PROSTATE CANCER PRODUCING SYNDROME OF INAPPROPRIATE SECRETION OF ANTIDIURETIC HORMONE; A CASE REPORT].

A 73-year-old man with progressive prostate cancer visited our hospital after prostate biopsy performed at another hospital. His serum PSA level was 29.02 ng/ml. CT revealed invasion of the bladder, bilateral ureters, and rectum. Otherwise, there was no evidence of metastasis. Pathological findings showed a poorly differentiated adenocarcinoma (Gleason score 4+5) and small cell carcinoma component. Two months after administering combined androgen blockade therapy, he was admitted due to severe hyponatremia caused by the inappropriate secretion of antidiuretic hormone. Furthermore, CT revealed right ureter metastasis, although the PSA levels remained low. Therefore, the patient was put on fluid restriction and sodium administration. After the patient recovered from hyponatremia, chemotherapy, including VP-16 and CDDP, was initiated. However, CT after two chemotherapy cycles revealed disease progression, with multiple bone metastases. Second-line chemotherapy, including CPT-11 and CDDP, was less effective, and the patient died 9 months after the diagnosis.

Continuous remission of renal cell carcinoma with tumour thrombus after severe adverse events following short-term treatment with sunitinib.

A 64-year-old Japanese man with renal cell carcinoma (RCC) and tumour thrombus in the inferior vena cava was treated with sunitinib. Two weeks after treatment, he was hospitalised for disturbance of consciousness. Laboratory tests revealed high-grade hypoglycaemia, hyponatraemia, liver dysfunction and thrombocytopaenia with disseminated intravascular coagulation. Sunitinib was discontinued and the patient recovered after a protracted platelet transfusion. At 5 months after treatment, CT revealed that the tumour thrombus had disappeared and other lesions had regressed. MRI at 15 months revealed further regression and suggested the possibility of histological remission according to the signal intensity of fibrosis. A partial response persisted at 20 months after treatment, despite residual accumulation in the renal tumour evident on positron emission tomography. In summary, we present a case of locally advanced RCC accompanied by severe adverse events that showed a significant and durable response to treatment with sunitinib for just 2 weeks.

Adaptive expression of uncoupling protein 1 in the carp liver and kidney in response to changes in ambient temperature.

The expression of uncoupling protein (UCP1) is up-regulated in mammalian brown adipocytes during cold exposure. However, a previous study revealed that UCP1 was highly expressed in the liver of common carps, and that the hepatic expression of UCP1 was down-regulated during cold exposure. The present study examined the effects of temperature on the recovery of UCP1 expression levels and the expression of genes involved in UCP1 transcription in the livers and kidneys of common carps. The hepatic and renal expressions of UCP1 were decreased by acclimation from 22 °C to 8 °C, and a subsequent increase in the water temperature from 8 °C to 28 °C recovered the renal, but not hepatic expression of UCP1. Changes in the expression of peroxisome proliferator-activator receptor (PPAR) γ, retinoid X receptor (RXR) α and PPARγ co-activator (PGC)-1α, genes that are involved in the expression of UCP1 in mammals, with ambient temperature indicated that the expressions of PPARγ and RXRα, but not expression of PGC-1α was decreased in response to cold exposure; the hepatic and renal expressions of PPARγ and RXRα recovered to basal levels with the cessation of cold exposure, although this was not complete for hepatic expression of PPARγ. The results of the present study indicate that a unique regulatory mechanism is responsible for the hepatic and renal expressions of carp UCP1 during cold exposure and subsequent reacclimation, and is distinct from that in murine brown adipocytes.

[Laparoscopic fenestration for a symptomatic lymphocele in renal graft after living-donor kidney transplantation].

A 36-year-old female received protocol biopsy at 1 month after living donor kidney transplantation. At 3 months post-transplantation, presence of a growing cystic mass in the kidney graft which had not been detected preoperatively, was demonstrated by ultrasound and computed tomography. The patient had an abdominal pain around the graft. Percutaneous drainage and sclerotherapy with minocyclin were performed twice, but the cystic mass, nevertheless, became enlarged and the abdominal pain recurred again. Laparoscopic fenestration was then performed. Immunohistochemistry of the cystic mass wall showed that it was CD34 (-), EMA (-), Megalin (-), but D2-40 (+). These results suggested that the cystic mass was derived from lymphatic vessels, which developed into lymphocele in the graft. We concluded that lymphatic vessels could have been injured and obstructed by the protocol biopsy. This is the first report of successful laparoscopic fenestration for lymphocele in the kidney graft.

Sexual satisfaction of infertile couples assessed using the Golombok-Rust Inventory of Sexual Satisfaction (GRISS).

Recently, infertility treatment-related psychological effects are receiving increased attention. However, whether sexual satisfaction is reduced amongst infertile couples remains to be elucidated. In this study, sexual satisfaction of Japanese infertile couples was assessed using a validated questionnaire designed to assess the male and female partner individually, and the couple as a whole for the first time. This study randomly included 170 infertile couples seen at the outpatient clinic and 170 couples that had recently achieved spontaneous pregnancy. All couples were given the Japanese version of the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). In couples aged 35 years or older, the male partners showed significantly worse sexual satisfaction scores than the female partners. Sexual satisfaction also deteriorated with therapeutic interventions, with mental factors affected more than physical factors. Therapeutic interventions such as timed sexual intercourse and assisted reproductive technology were considered emotionally stressful for infertile couples, with sexual satisfaction accordingly lower in this group than in couples achieving spontaneous pregnancy. GRISS successfully evaluated lower sexual satisfaction associated with infertility, and hence is a useful tool for identifying couples whose sexual satisfaction could be enhanced by counselling or other stress-reduction modalities.

Cardiomyocyte-derived mitochondrial superoxide causes myocardial electrical remodeling by downregulating potassium channels and related molecules.

BACKGROUND: This study was designed to investigate the role of a primary hyperoxidative stress in myocardial electrical remodeling using heterozygous heart/muscle-specific manganese superoxide dismutase-deficient (H/M-Sod2(+/-)) mice treated with L-buthionine-sulfoximine (BSO). METHODS AND RESULTS: Both H/M-Sod2(+/-)and wild-type (WT) mice were treated with intra-peritoneal BSO or saline for 7 days, and divided into 4 groups: H/M-Sod2(+/-)+BSO, WT+BSO, H/M-Sod2(+/-)control, and WT control. The ventricular effective refractory period (ERP) and the monophasic action potential duration (MAPD) were determined. Levels of oxidative stress, potassium channel-related molecules, and K(+)channel-interacting protein-2 (KChIP2) were also evaluated. The H/M-Sod2(+/-)+BSO group exhibited markedly prolonged MAPD20, MAPD90 and ERP in comparison with the other groups (MAPD20: 14 ± 1 vs. 11 ± 1 ms, MAPD90: 77 ± 7 vs. 58 ± 4 ms, ERP: 61 ± 6 vs. 41 ± 3 ms, H/M-Sod2(+/-)+BSO vs. WT control; P<0.05). Mitochondrial superoxide and hydrogen peroxide formation in the myocardium increased in the H/M-Sod2(+/-)+BSO group in comparison with the WT+BSO group (P<0.05). Real-time RT-PCR and Western blotting revealed that Kv4.2 expression was downregulated in both BSO-treated groups, whereas KChIP2 expression was downregulated only in the H/M-Sod2(+/-)+BSO group (P<0.05). CONCLUSIONS: BSO treatment caused hyperoxidative stress in the myocardium of H/M-Sod2(+/-)mice. Changes in the expression and function of potassium channels were considered to be involved in the mechanism of electrical remodeling in this model.

Usefulness of a simple prognostication score in prediction of the prognoses of patients with out-of-hospital cardiac arrests.

Sudden cardiac death is a serious problem in public health but the overall survival rate of out-of-hospital cardiac arrests (OHCAs) remains low. In this study, we identified clinical parameters to predict the prognosis of OHCA patients and proposed a simple prognostication score for prediction of their prognoses. The study population consisted of 750 consecutive patients with OHCAs of internal cause who were transported to our institute from July 2008 to June 2010. They were divided into survivors and nonsurvivors, and clinical parameters were compared between them to detect significant parameters for prediction of their prognoses. The population of those who survived at 1 month numbered 34. Multivariate analysis exhibited 10 independent predictive factors of survival, which included witnessed cardiac arrest and bystander-initiated CPR. When the prognostication score was calculated from these independent predictive factors, a score of ≥ 6 points indicated survival with a sensitivity of 88.6% and a specificity of 97.6%. When the patients were divided into younger and older populations with a threshold of 70 years, these values were 94.1% and 96.1% in younger but 70.0% and 98.4% in older patients, respectively. In retrospective observation, a simple prognostication score was useful to predict patient prognoses in OHCAs, but its usefulness was limited in an older population.

Readily-milled fraction of wet sugarcane bagasse as an advanced feedstock for monosaccharide production via the RT-CaCCO process.

The RT-CaCCO process for enzymatic saccharification was applied to readily-milled fractions of wet sugarcane bagasse. Wet bagasse immediately after juice extraction was crushed with shark-mill blades to prepare two fractions referred to as readily-milled (RF) and hardly-milled fraction (HF). Monosaccharide recoveries from RFs via the RT-CaCCO process were 1.03-1.21 times higher than those from HFs. Moreover, when the wet weight ratio of RF/HF was adjusted to 2/8, the hexose recovery from RF was 90.9%, which was 1.3 times higher than that of the wet bagasse before fractionation. The results show that this process can be used for efficient monosaccharide recovery from RF of wet bagasse. In addition, the process can be adapted to more fibrous HF for multiple uses such as fuel for boilers and fibers for particleboards.

Evaluation of the impact of atrial fibrillation on rehospitalization events in heart failure patients in recent years.

BACKGROUND: Although we have previously reported that the presence of paroxysmal atrial fibrillation (AF) is an independent risk factor for rehospitalization in patients with congestive heart failure (CHF) in a population from 1996 to 2002, the impact of AF configuration as a risk factor in a more recent population remains to be clarified. METHODS AND RESULTS: 319 patients with CHF admitted to our institute in 2006-2007 were retrospectively evaluated. The patients were divided into 3 groups in accordance with their basic cardiac rhythm, i.e. sinus rhythm (n=210), chronic AF (n=68), and paroxysmal AF (n=41). During the follow-up period of 19 ± 17 months, there was no significant difference in mortality or rehospitalization events among the 3 groups (p=0.542). In the multivariate analysis, no administration of ß-blockers was the only independent risk factor for rehospitalization due to CHF exacerbation. CONCLUSIONS: The clinical impact of AF configuration as a risk factor of rehospitalization due to CHF exacerbation was considered to be decreased in recent years.

Repetitive evaluation of fibrillation cycle length predicts the efficacy of bepridil for interruption of long-lasting persistent atrial fibrillation.

Although bepridil is effective for conversion of long-lasting persistent atrial fibrillation (AF) to sinus rhythm, it sometimes takes a long time to interrupt AF and there is no feasible index to predict its efficacy.In 60 patients with long-lasting persistent AF, bepridil (100-200 mg/day) was administered and continued for 8 weeks while body surface ECG was recorded every 2 weeks. The fibrillation cycle length (FCL) was evaluated using the spectral analysis of the fibrillation waves in each ECG. AF was interrupted in 32 patients receiving bepridil. The conversion was observed at 2 weeks in 4, at 4 weeks in 7, at 6 weeks in 7, and at 8 weeks in 14 patients. When comparing these responders and nonresponders, clinical background characteristics other than the dosage of bepridil did not show any difference and neither did temporal changes in QT parameters and heart rate. In contrast, the FCL and ΔFCL (prolongation in FCL from baseline) became significantly larger in responders than in nonresponders at later observation points (FCL: 177 ± 17 versus 164 ± 19 ms, P = 0.018, and ΔFCL: 38 ± 16 versus 22 ± 12 ms, P < 0.001, at 4-week point; FCL: 188 ± 17 versus 169 ± 19 ms, P = 0.004, and ΔFCL: 49 ± 18 versus 27 ± 14 ms, P < 0.001, at 6-week point).Repetitive evaluation of FCL using spectral analysis of fibrillation waves can be a feasible index to predict the efficacy of bepridil therapy.

Efficient conversion of sugarcane stalks into ethanol employing low temperature alkali pretreatment method.

An alternative route for bio-ethanol production from sugarcane stalks (juice and bagasse) featuring a previously reported low temperature alkali pretreatment method was evaluated. Test-tube scale pretreatment-saccharification experiments were carried out to determine optimal LTA pretreatment conditions for sugarcane bagasse with regard to the efficiency of enzymatic hydrolysis of the cellulose. Free fermentable sugars and bagasse recovered from 2 kg of sugarcane stalks were jointly converted into ethanol via separate enzymatic hydrolysis and fermentation (SHF). Results showed that 98% of the cellulose present in the optimally pretreated bagasse was hydrolyzed into glucose after 72-h enzymatic saccharification using commercially available cellulase and ß-glucosidase preparations at relatively low enzyme loading. The fermentable sugars in the mixture of the sugar juice and the bagasse hydrolysate were readily converted into 193.5 mL of ethanol by Saccharomyces cerevisiae within 12h, achieving 88% of the theoretical yield from the sugars and cellulose.
