Bacterial communities in ancient permafrost profiles of Svalbard, Arctic
Permafrost soils are unique habitats in polar environment and are of great ecological relevance. The present study focuses on the characterization of bacterial communities from permafrost profiles of Svalbard, Arctic. Counts of culturable bacteria range from 1.50 × 10 3 to 2.22 × 10 5 CFU g −1 , tot...

Permafrost soils are unique habitats in polar environment and are of great ecological relevance. The present study focuses on the characterization of bacterial communities from permafrost profiles of Svalbard, Arctic. Counts of culturable bacteria range from 1.50 × 10 3 to 2.22 × 10 5 CFU g −1 , total bacterial numbers range from 1.14 × 10 5 to 5.52 × 10 5 cells g −1 soil. Bacterial isolates are identified through 16S rRNA gene sequencing. Arthrobacter and Pseudomonas are the most dominant genera, and A. sulfonivorans , A. bergeri , P. mandelii , and P. jessenii as the dominant species. Other species belong to genera Acinetobacter , Bacillus , Enterobacter , Nesterenkonia , Psychrobacter , Rhizobium , Rhodococcus , Sphingobacterium , Sphingopyxis , Stenotrophomonas , and Virgibacillus .
