Abstract:

Biodiversity of bacteria in the top layer of the sediment from Northern Bering Sea was studied by a combination of RFLP and 16S rDNA analysis. Phylogenetic analysis showed that bacterial community composition of the sediment had a high diversity. 124 clones from the 16S rDNA library fell into ten bacterial groups,including Proteobacteria (49.6%),Acidobacteria (20.8%),Bacteroidetes (6.4%),Actinobacteria (5.6%),Planctomycetes (5.6%),Nitrospirae (4%),Verrucomicrobia (2.4%),Chloroflexi (1.6%),Fibrobacteres (0.8...

Key words: Northern Bering Sea, sediments, bacteria, diversity
