gen. nov., sp. nov., a sessile bacterium isolated from coral .

A Gram-stain-negative, non-spore-forming, motile, aerobic bacterium (strain C21) was isolated from coral and identified using polyphasic identification approach. Global alignment of 16S rRNA gene sequences indicated that strain C21 shares 95.7 % sequence identity to its closest neighbour, NBRC 110095, followed by other type strains with identities of lower than 95 %. The average nucleotide identity and average amino acid identity values between strain C21 and NBRC 110095 were 69.6 and 64.8 %, respectively, indicating that strain C21 may represent a new species in a new genus. Phylogenetic analysis based on 16S rRNA gene and phylogenomic results indicated that strain C21 forms a distinct branch in the family . Cellular fatty acids and polar lipids could also readily distinguish strain C21 from closely related type strains. Therefore, strain C21 is suggested to represent a new species in a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain is C21 (=MCCC 1K03260=KCTC 62317).
