Removal of inhibitors of microbial fermentation of Cellulosic hydrolysates or other compositions containing inhibitors

摘要

Methods to prepare hydrolyzed Cellulosic biomass to remove or inactivate inhibitors of microbial Development and / or production of Metabolites. The Methods include precipitation, or deactivation of inhibitors with Calcium Hydroxide and Potassium hydroxide.Claim 1: a method to reduce the amount of an inhibitor of microbial Growth and / or the microbial production of organic products in a hydrolysed Cellulosic Biomass, characterized in that it comprises: contacting the hydrolysate with hydroxide and Calcium Hydroxide POTASSIUMWhere at least a portion of the inhibitor forms a precipitate in the presence of Calcium Hydroxide and Potassium hydroxide precipitate; and separate hydrolysate hydrolyzed to form a conditioning.
