Abstract
Marine microorganism and organism communities are very dynamic and changeable in responds to environmental factors. Therefore the understanding of marine bacteria diversity and community could improve perception to further environmental changes and ecosystem level, even infer the unclear microbes control factors. Additionally regarding the conservation of marine ecosystem pathogenic bacteria to cause disease of human and marine organism have been increasingly considerable. Recently sequencing technic has been developed as next generation sequencing (NGS) which make possible to study taxonomic diversity with 16s rRNA gene. In the present study, we investigated bacterial community at three different areas including Jeju island, Somaemul island, Ulleung island on East Korean Warm Current through 16s rRNA gene pyrosequencing analysis. In addition, marine pathogenic bacteria list were deducted in each places. The seawater samples were collected in March 2015. In our result, bacteria diversity was more than 500 Operational Taxonomic Units (OTUs), and Jeju island took the highest diversity index score and most numerous pathogenic bacteria had been detected among all samples. In contrast the ratio of pathogenic bacteria was highest at Somaemul island. Additionally the common pathogenic bacteria from both Jeju and Somaemul island were more present than those from both Somaenul and Ulleung island.nges and ecosystem level, even infer the unclear microbes control factors.
