Abstract:

Bacterial diversity in sea ice brine samples which collected from four stations located at the Canada Basin,Arctic Ocean was analyzed by PCR-DGGE.T wenty-three 16S rDNA sequences of bacteria obtained from DGGE bands were cloned and sequenced.Phylogenetic analysis clustered these sequences within γ-prote obacteria, Cytophaga-Flexibacter-Bacteroides (CFB) group, Firmicutes and A ctinobacteria. The phylotype of Pseudoalteromonas in the γ-proteobacteria was predominant and members of the CFB group and γ-proteobacteria were highly abundant in studied sea ice brine samples.

Key words: sea ice brine, Arctic, bacteria, 16S rDNA, phylogenetic
