摘要： A method for obtaining a fermentation product from a sugar hydrolysate obtained from a feedstock containing hemicellulose, by (i) removing suspended fiber solids from said sugar hydrolysate to obtain a clarified sugar solution; (ii) fermenting xylose in the clarified sugar solution in a fermentation reaction with yeast to produce a fermentation broth comprising the fermentation product; (iii) separating the yeast from the fermentation broth to produce a yeast slurry; (vi) treating the yeast slurry thus obtained with an oxidant to kill microbial contaminants, thereby an oxidant-treated yeast slurry; (v) re-introducing at least a portion of the oxidant-treated yeast back to step (ii) to increase the concentration of yeast in said fermentation reaction; and (vi) recovering the fermentation product.

摘要： A fermentation process using hemicellulose-derived carbohydrates for the production of cellulase mixtures with a high proportion of cellulases relative to hemicellulases is provided. The cellulases produced by the process of the invention are further characterized by high specific productivity. The resulting cellulase mixtures comprise at least two times more cellulase than hemicellulase and are useful for the hydrolysis of cellulosic substrated, particularly, pretreated lignocellulosic substrate.
