Bacterial isolation and diversity analysis of four seawater sampling sites of the East China Sea and the South China Sea
A total of 105 strains were obtained from four sampling sites of the East China Sea and the South China Sea. Bacterial diversity and characteristics of bacteria communities were investigated. According to 16S rRNA gene sequences alignment, strains isolated from the East China Sea belong to 2 phyla and 14 species and strains isolated from the South China Sea belong to 3 phyla and 19 species. Strains isolated from the East China Sea were composed by γ-proteobactena (57. 2%), crproteobactena (33. 3%) and Firmicutes (9. 5 %). Strains isolated from the South China Sea composed by y-proteobactena (35. 5 %), orproteobactena (41.9%), Bacteroidetes (17.7%) and Firmicutes (4. 8%). Composition of isolated strains in genus and species level of the East China Sea and the South China Sea were significantly different. Microbial diversity of strains from the East China Sea was higher than that of the South China Sea.
