[Objective]The research aimed to separate and identify psychrotolerant bacteria from low temperature biomembrane.[Method]Psychrotolerant bacteria was separated and purified from low-temperature membrane, then physiological and biochemical identification of them was carried out and the growth curve of them at 4 ℃ and 30 ℃ was measured.[Result]There were many kinds of microbes which composing the low-temperature membrane,8 kinds among them belonged to Comamonas,Flavobacterium,Arthrobacter,Bacillus,Micrococcus,Pseudomona,Achromobacter,Vibrio, named S1,S2,S3,S4,S5,S6,S7,S8,respectively.S3 growed fastest and S2 growed slowest,the other 6 kinds growed with almost the same speed.All of the 8 kinds of microbes growed faster under 30 ℃ than under 4 ℃,and after 24 h they reached exponential phase.[Conclusion]This study was meaningful for the settlement of problems in sewage treatments under low temperature.
