Strategy for simultaneous saccharification and fermentation using a respiratory-deficient mutant of Candida glabrata for bioethanol production

High temperature and agitation are advantageous for ethanol production from insoluble feedstock when using the simultaneous saccharification and fermentation (SSF) technique. To construct an effective SSF system, a respiratory-deficient mutant was isolated from the thermotolerant yeast Candida glabr...

Description
Summary:High temperature and agitation are advantageous for ethanol production from insoluble feedstock when using the simultaneous saccharification and fermentation (SSF) technique. To construct an effective SSF system, a respiratory-deficient mutant was isolated from the thermotolerant yeast Candida glabrata. Our results suggest that this respiratory-deficient mutant has higher ethanol production abilities in SSF.
