Abstract

A surfactant-improved simultaneous saccharification and co-fermentation method for lignocelluloses in which a pretreated lignocellulose substrate is directly subjected to surfactant-improved simultaneous saccharification and co-fermentation without any detoxification by adding a surfactant, and the surfactant may be selectively added before or after pre-enzymatic hydrolysis, having economic, effective and feasible application prospects in reducing the loss of glucose, simplifying the production process, reducing equipment investment, reducing water consumption, improving ethanol production and reducing the total cost of the ethanol production process.
