Saccharification and detoxification of Na2CO3 pretreated rice straw with on-site manufactured enzymes secreted by Aspergillus fumigatus to enhance bioethanol yield

Enzyme production as well as rice straw saccharification and fermentation were integrated to produce bioethanol in this study. Submerged fermentation of Na2CO3 pretreated rice straw to produce a complex enzyme for saccharification by Aspergillus fumigatus was performed. The major component of rice straw, that is cellulose, hemicellulose and lignin was almost completely degraded in 24 h. Using whole pretreated rice straw slurry as the substrate,...
