Abstract

This Small Business Innovation Research project is to develop a novel two-stage hydrolysis and fermentation process for conversion of purified cellulose to ethanol. The process would be part of a larger biomass refining system in which lignocellulosic biomass would first be fractionated into a hemicellulose / lignin stream and a purified cellulose stream. The specific objectives of this project are to identify optimal conditions for simultanous saccharification and fermentation of partially hydrolyzed cellulose to ethanol and to evaluate the economics of the overall process.
