The invention relates to a new method of co-fermenting kitchen waste raw materials with mixed bacteria for producing fuel ethanol, which is characterized by comprising the following steps: 1, separating and screening a rhizopus oryzae strain which simultaneously has amylase activity and cellulase activity; and 2, taking the kitchen waste as a raw material only, and mixing the rhizopus oryzae and saccharomyces cerevisiae in a certain proportion for co-fermenting to produce the fuel ethanol. The method of the invention avoids the problems that in the process of fermenting the kitchen waste for producing the fuel ethanol, the raw material can not hydrolyze because of enzymic inactivation, glucose is lacked in the fermentation liquor, and ethanol fermentation can not be completely carried out. No catalyst and nutrient need to be added in the fermentation process, the availability of large molecule organic substances of starch, cellulose and the like in the waste is high, thus the invention ...
