Phylogenetic analysis of bacteria in sea ice brine sampled from the Canada Basin,Arctic Ocean |
| |
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. |
