High-concentration mash fermentation has such characteristics as high cell density,high product concentration and high production rates. So it is the future aim of ethanol industry. High-concentration mash ethanol fermentation techniques have the advantages of saving process water,improving equipment utilization,and reducing energy consumption. So high-concentration mash ethanol fermentation techniques are an important way of improving ethanol production efficiency. Research on high-concentration mash ethanol fermentation techniques is very important in practical application. This paper reviews research progress of high-concentration mash ethanol fermentation techniques. The definition,advantages and influencing factors of high-concentration mash ethanol fermentation are introduced. Lowering the viscosity of fermentation mash,screening high-tolerance ethanol yeast,changing fermentation process model and adding appropriate enzymes and nutrients are important methods of achieving high-concentration mash ethanol fermentation. Among them,screening high-tolerance ethanol yeast is the key to high-concentration mash fermentation.
