Abstract:To reveal the diversity and difference of marine bacteria in the sediment of the Northern Yellow Sea, the 16S rDNA clone library technique was used to analyze the characteristics of bacterial community at different seasons from the five stations of the Northern Yellow Sea. The 16S rDNA clone library analysis indicated that the sediments contained high diverse of bacteria and mainly distributed in five to ten known phyla, and most of sequences were affiliated to uncultured bacteria. Phylogenetic analysis showed that the Proteobacteria was the dominant group in the sediments, accounting for 46%~60% of total sequences, and γ-Proteobacteria and δ-Proteobacteria were dominant classes. However, all proteobacterial classes presented phylogenetical divergence at the five stations. The bacterial community diversity differed due to the geographical location and season, and different function microbial groups were closely related to their special habitats.
