The invention discloses a method for increasing the butanol-acetone ratio and the butanol yield of clostridia ABE fermentation, and belongs to the technical field of biology. According to the method, corn flour is taken as a fermentation raw material, and a clostridium-saccharomyces cerevisiae mixed culture system is formed by appropriately adding an active saccharomyces cerevisiae and a butyric acid solution at the solvent production stage of the clostridia. The saccharomyces cerevisiae is capable of secreting various amino acids under a strict anaerobic condition and in a severe saccharomyces cerevisiae growth environment, wherein aromatic amino acids and aspartic amino acids all advantageous for butanol synthesis are greatly accumulated. On the basis, the small amount of added butyric acid is further capable of weakening the metabolism intensity of the closed loop of butyric acid. Under the dual combined action, the butanol-acetone ratio and the final butanol concentration of the ABE fermentation can be greatly improved under the premise of unchanged or slightly improved total solvent production intensity. The two indexes, namely butanol-acetone ratio and butanol concentration of the method are at the highest level in the related study reports of the batch fermentation production of butanol by use of wild clostridia and have important guiding significance for the ABE fermentation.
