INTEGRATED PROCESSES FOR CONVERSION OF LIGNOCELLULOSIC BIOMASS TO BIOPRODUCTS AND SYSTEMS AND APPARATUS RELATED THERETO

摘要

An integrated biological process for cellulosic bioproduct production is provided, which, in one embodiment, results in high ethanol productivity, enzyme recycling and reuse of yeast cells. The integrated process can be an integrated separate hydrolysis and fermentation (SHF) process or an integrated fast simultaneous saccharification and co-fermentation (FSSCF) process. The methods described herein can result in high bioproduct productivity through enzyme recycling and reuse of yeast cells.

主权项

1. A method comprising:
performing a first hydrolyzing cycle on lignocellulosic biomass containing an easily digestible portion and a non-easily digestible portion, to produce a slurry containing digested solids and unhydrolyzed solids, respectively; and producing a solids residue and a liquid coproduct from the slurry.
