青海湖嗜盐微生物筛选分离与生长特性
Isolation and characteristics of halophile microorganisms from Lake Qinghai
摘要
Abstract
The main objective of the project is to obtain completely halophile germplasm resources from Lake Qinghai, to construct stocks phyletic evolution tree of halophilic bacterium and determine the evolution position. 35 strains were isolated from 20 water samples taken from Lake Qinghai using the high salty medium. Resistant to salt gradient experiment shows that moderate halophilic bacteria account for about 62. 85% in the water, mild halophilic bacteria account for about 22. 85% , non halophilic bacteria and salt resistance bacteria account for 14.28% . Moderate halophilic bacteria could grow in the temperature of 10~45℃ and pH 5.5-11.0, which is related to the local salinization environment and has characteristic of hasophilic microorganisms.关键词
