Abstract

Sea squirt is an important source for isolation of new bacteria strains that are able to accumulate bio-active compounds. In this study, we isolated and identified of cultivable bacteria isolated from sea squirt Ciona savignyi, collected from the Tsingtao Port, Jiaozhou Bay, China. We investigated the phenotypic characteristics and neighbour-joining phylogenetic analysis of this isolated cultivable strains, which suggested the isolated seventeen strains mainly belong to the Proteobacteria, Bacteroidetes and Actinobacteria four phyla, of which twelve strains belong to Proteobacteria, accounted for 70.6% of total isolated stains, and respectively belonging to Alphaproteobacteria and Gammaproteobacteria. This identification and analysis of this these marine bacteria will enrich sea squirt-associated bacteria resources, from which more bio-active substances would be discovered.
