Abstract

Abstract:

The samples from the South Lake at a low temperature were taken and diluted onto coated tablet for concentration inoculation. A total of 35 coldadaptedstrains were isolated, which contained 14 bacteria and 21 fungi. The colony morphology and physiological and biochemical results show that the psychrotrophic bacteria belong to Lactobacilus, Saccharococcus, Staphyloccus, Actinomyces and the fungi belong to molds and yeast. Some of them can produce hydrolases including oxidase, catalase, amylase and gelatinase, and some of psychrotrophs can make nitrate reduction, nitrite reduction and so on.

Key words: lake, psychrotrophic bacteria, identification, character
