TL;DR: In this article, a linear relationship was found between the total fermentable sugar concentrations and Brix degrees of the juices, which can predict the potential ethanol yield by field analytical tests, and three experimental sweet sorghum varieties (M81, Topper and Theis) and three post-harvest conditions were evaluated for ethanol production.

TL;DR: In this article, the acid pretreatment of napiergrass was used to obtain high yields of sugars and low level of degradation byproducts from hemicellulose, and the highest cellulose hydrolysis values were found with the addition of β-glucosidase and PEG 6000.

TL;DR: Proteases able to unhair sheep skins were produced from Bacillus subtilis using a mixture of metallo- and serine-proteases with optimal pH and temperature for protease activity at 7 and 50-55°C, respectively.

TL;DR: In a search for microorganisms producing extracellular protease with unhairing activity, Bacillus subtilis IIQDB32 was isolated and was significantly stimulated by glucose, tryptone, yeast extract, Ca2+ and Mn2+, but was repressed by ammonia and Fe2+.

TL;DR: The enzymatic starch hydrolysis and bioethanol production from a variety of sweet potato developed for bioenergy purposes, was studied, and high ethanol yields were found for VHG (very high gravity) conditions.
