Abstract: The psychrophilic bacteria present in raw milk can grow under cold storage conditions and secrete protease and lipase which degrade milk protein and fat, resulting in the deterioration of milk quality. The present article summarizes the major species of psychrophilic bacteria in raw milk, with an emphasis on the recent progress that has been made in understanding the hazards of psychrophilic Bacillus including their species, hazard characteristics, proteases and lipases. At last, the future research direction of psychrotrophilic Bacillus is discussed.

Key words: psychrophilic bacteria species; Bacillus spp.; protease; lipase
