The use of straw and forestry waste to produce fuel ethanol is the problem of food, energy and environmental issues such as the effective method, also contribute to the solution of straw in situ burning cause environmental pollution and resource waste problem, accord with the demand of sustainable development can be. Research shows that synchronization saccharification fermentation is the preparation before the eyes of cellulosic ethanol ideal process, this is because with the traditional step saccharification fermentation method, compared with synchronous saccharification fermentation under the advantages: (1) can eliminate glucose accumulation on cellulose enzyme system feedback inhibition, improve the utilization rate of enzyme and the ethanol yield rate; (2) the simplify production process, save equipment investment; (3) continuous generation ethanol and maintain a low sugar concentration, can reduce the risk of the mixed fungus pollution. So is acknowledged as the most promising cellulose ethanol fermentation method.
