Title:
METHOD FOR PRODUCING CELLULOSIC ETHANOL
Document Type and Number:
WIPO Patent Application WO/2010/072093
Kind Code:
A1
Abstract:
A method for producing cellulosic ethanol is disclosed, which comprises the following steps: 1) adding the medium containing the source materials of cellulose and/or hemicellulose to fermentation reaction vessel; 2) adding cellulase to fermentation reaction vessel, and inoculating Candida lusitaniae; 3) running simultaneous saccharification fermentation (SSFs) with the combined action of cellulose and Candida lusitaniae, and obtaining cellulosic ethanol by separation. Candida lusitaniae used in SSFs in present invention has higher ethanol tolerance and a higher ethanol production rate, it can use cellulose and hemicellulose as source materials and effectively produce cellulosic ethanol with cellulase in SSFs.
