Production of Ethanol from Biomass Using Dicarboxylic Acids
Researchers at Purdue University have developed a process for converting lignocellulosic biomass to ethanol that results in an ethanol yield of approximately 90 percent. This process includes treating lignocellulosic biomass with a dicarboxylic acid to hydrolyze hemicellulose and lignocellulosic biomass to xylose. This results in minimal formation of degradation products. Lower amounts of degradation product allows for less enzymes or yeast used, resulting in a ready fermentation of the xylose to ethanol using a yeast without the necessity of purifying material.
Minimal degradation in ethanol production Decreases the number of enzymes or yeast used in the fermentation of ethanol
