| An investigation was done that the diversity and distribution of heterotrophic bacteria in the adjacent area of four main monitored discharge outlets in Bohai,which located in Beitang,Dapuhe,Mihe and Yuhe,resectively.The results showed that all the isolated bacterial strains belonged to four phyla,including Proteobacteria,Firmicutes,Actinobacteria and Bacteroidetes,in which Proteobacteria was the dominant phyla.Furthermore,the dominant bacteria of four sampling locations are different.To be specific,Bacillus sp.and Pseudoalteromonas sp.were found to be dominant in Beitang and Mihe,respectively.Vibrio sp.and Oceanospirillum sp.were prevailing in Dapuhe,while the dominant bacteria of Yuhe were Shewanellasp.and Bacillussp.Results of MDS analysis indicated that the bacterial population characteristics from Beitang and Yuhe were similar to each other,suggesting that the diversity and distribution of bacteria probably be related with the marine environment. |
