Banana peels belong to lignocellulosic substrates, which can be used as raw material for bioethanol. Yeast plays an essential role in bioethanol fermentation. The study aims compare ethanol yield using two different yeasts: Saccharomyces cerevisiae and Rhizopus oryzae, with yeast concentrations of 2, 3, 5 g/L. fermentation is run at room temperature 120 hours. Results show that R. oryzae...

A collection of 33 Saccharomyces yeasts were used for wine fermentation with a sole nitrogen source: ammonium and four individual aroma-inducing amino acids. The performance chemical composition evaluated. most valuable sources valine as promoter on non-cerevisiae strains, phenylalanine fruity aromas enhancer whereas the ethanol yield was lessened by leucine isoleucine. S. cerevisiae SC03 kudri...

The aim of present study is investigating effect of treated lemon pulp by Saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. In this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by Saccharomyces cerevisiae yeas...

There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

Yeast Saccharomyces cerevisiae is one of the simplest eukaryotic model organisms to study various parameters ethanol tolerance and has attracted a huge consideration for cost-conscious production bioethanol by fermentation soluble sugars. Ethanol crucial efficient from S. cerevisiae. In this study, we examined role HAL5 protein kinase in comparing cell growth, survival, stress responses wild-ty...

Abstract Bioethanol production has been a challenge for the researchers with respect to enhancing bioethanol yield. In this study, we are reporting an efficient novel method produce bioethanol. The process comprises co-culture technique from wheat straw, by co-culturing Bacillus licheniformis and Saccharomyces cerevisiae. Simultaneous saccharification fermentation allows straw hydrolysis cellul...
