英文摘要	The current study deals with the diversity and distribution of culturable cold-adapted bacteria in Himalayan Thajwas glacial soil. The total bacterial count of the seven soil samples collected near glacier snout at different altitudes was investigated through a culture-dependent method. The highest cfu/g (6.8 +/- 2 x 10(7)) was recorded at site I, and the lowest cfu/g (4.6 +/- 2 x 10(3)) was recorded at site VII on nutrient agar (NA) media. The 31 isolated strains were identified using 16S rRNA gene sequencing. Based on their optimum growth at different temperatures, these bacterial isolates were categorized into two overlapping groups: psychrophiles (optimum growth >= 15 degrees C) and psychrotrophs (optimum growth >= 20 degrees C). Besides, these bacterial strains were screened for their cold-active enzyme activity. Further, the microbial diversity was affected by higher incubation temperature, which reduced the richness due to the selection of psychrotrophic microorganisms. Variation in microbial diversity may be related to soil physicochemical properties since a high positive correlation was observed with water content, total nitrogen and organic carbon. This is the first research to look at microbial communities from the Thajwas Glacier, and it adds to our knowledge of the microbial diversity found in Himalayan cold ecosystems.
