Sweet sorghum (Sorghum bicolor (L.) Moench) is a promising energy crop for biofuel production. A demonstration study on cost-effective conversion of fermentable sugars in sweet sorghum stems into ethanol with advanced solid-state fermentation technology is presented in this paper. A continuous...

This paper examines the possibilities of breaking into the cellulosic ethanol market in south Louisiana via strategic feedstock choices and the leveraging of the area’s competitive advantages. A small plant strategy is devised whereby the first-mover problem might be solved, and several...

Energy crops constitute significant potential for meeting the future energy need worldwide. In addition, agricultural lands offer an alternative to the agriculture which is referred to as energy farming. The studies on energy crops in biofuel production show that they are quite an economical and...

Dried spent yeast (DSY) and its hydrolysate (DSYH) were used as low-cost nitrogen supplements to improve ethanol production from sweet sorghum juice by<i> Saccharomyces cerevisiae </i>NP01 under very high gravity (VHG) fermentation (280 g·L⁻¹ of total sugar) conditions. The supplemented DSY and DSYH...

Bioethanol is a promising biofuel and has a lot of great prospective and could become an alternative to fossil fuels. Ethanol fermentation using glycerol as carbon source was carried out by local isolate, ethanologenic bacterium Escherichia coli SS1 in a close system. Factors affecting...
