NUMERICAL TAXONOMY OF MODERATELY HALOPHILIC BACTERIA ISOLATED FROM SALT LAKES IN XINJIANG REGION / 微生物学通报

ABSTRACT

Twenty nine moderately halophilic bacteria isolated from salt lakes in Xinjiang Region were compared with nine reference strains of relative species by performing a numerical analysis of 112 phenotypic characteristics. All the new isolates are Gram negative and can grow on the media containing 0～25% NaCl. The results showed that all tested strains were clustered into 2 phena at 76 % similarity level. Phenon I was composed by 25 new isolates strains,and phenon II included 9 reference strains and 4 new lsolated strains. Most of the new isolated strains were clusted into 3 subphena at 86 % similarity level. There were 10 new isolated strains in subphenon 1, 8 new isolated strains in subphenon 2, and 1 new isolated strain and 5 reference strains were included in subphenon 3. The results indicated that there were great differences between the new isolates and the reference strains.
