Bioconversion of brewer's spent grains to bioethanol

Bioethanol from Brewer’s and Distiller’s Spent Grains

Second Generation Ethanol Production from Brewers’ Spent Grain

Ethanol production from lignocellulosic biomasses raises a global interest because it represents a good alternative to petroleum-derived energies and reduces the food versus fuel conflict generated by first generation ethanol. In this study, alkaline-acid pretreated brewers’ spent grain (BSG) was evaluated for ethanol production after enzymatic hydrolysis with commercial enzymes. The obtained h...

Bioconversion of lignocellulosic waste to bioethanol by Trichoderma and yeast fermentation

The present work aimed at producing bioethanol using lignocellulosic waste sawdust and marine yeast fermentation. Lignocellulosic waste materials were converted into monosugars through acid hydrolysis and finally treated with cellulase enzyme derived from Trichoderma/Hypocrea. To enhance the conversion of the glucose from sawdust, the experimental conditions were statistically optimized. The ef...

Bioconversion of cotton waste from textile mills to bioethanol by microbial saccharification and fermentation

Energy flows from many sources, exists in a variety of interchangeable forms, and drives all systems. New and renewable sources of energy can make significant contribution, but their role and potential in the short term should not be overstated. It has been estimated that new and renewable sources of energy at present meet only 5-10 per cent of global energy-requirements, which may hopefully go...

Bioconversion of Bamboo to Bioethanol Using the Two-stage Organosolv and Alkali Pretreatment

Bamboo’s ability to grow on nutrient-poor soils, with little requirement of silvicultural management, easy harvesting characteristics, vegetative propagation, fast growth, and a host of other desirable characteristics, make it a good candidate as an energy crop. Energy crops are cultivated solely for use as sources of energy through their conversion into alcohols. This study set out to determin...
