Efficient process for producing saccharides and ethanol from a biomass feedstock

摘要

Described herein is a process for producing saccharides and ethanol from biomass feedstock that includes (a) producing an enzyme composition by culturing a fungal strain(s) in the presence of a lignocellulosic medium, (b) using the enzyme composition to saccharify the biomass feedstock, and (c) fermenting the saccharified biomass feedstock to produce ethanol. The process is scalable and, in certain aspects, is capable of being deployed on farms, thereby allowing local production of saccharides and ethanol and resulting in a reduction of energy and other costs for farm operators. Optional steps to improve the biomass-to-fuel conversion efficiency are also contemplated, as are uses for byproducts of the process described herein.

主权项

1. A process for converting a biomass feedstock to a saccharide, the method comprising contacting the biomass feedstock with an enzyme composition, wherein the enzyme composition is produced by culturing Trichoderma SG2, Trichoderma SG4, or a combination thereof, in the presence of a lignocellulosic medium and a starch.
