ABSTRACT
A Gram-stain-positive, aerobic bacterium, designated as YPD9-1T, was isolated from the gut contents of a spotty belly greenling, Hexagrammos agrammus, collected near Dokdo island, South Korea. The rod-shaped cells were oxidase-positive, and catalase-negative. The major cellular fatty acids were anteiso-C15ââ0, iso-C15ââ0, C16ââ0, iso-C16ââ0 and iso-C17 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified lipids. The DNA G+C content was 47.6 mol% and the predominant respiratory quinone was menaquinone MK-7. The 16S rRNA gene sequence of YPD9-1T showed low sequence similarities to species of the genus Paenibacillus, Paenibacillus pocheonensis Gsoil 1138T (97.21â% of sequence similarity), Paenibacillus aestuarii CJ25T (97.12â%) and Paenibacillus allorhizoplanae JJ-42T (96.89â%). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that YPD9-1T formed a distinct branch among other species of the genus Paenibacillus. The digital DNA-DNA hybridisation, average nucleotide identity, and average amino acid identity values between YPD9-1T and the related species were in the ranges of 15.3-16.2â%, 74.1-78.4â%, and 71.1-71.9â%, respectively, which are below the species cutoff values. On the basis of the results of the polyphasic analysis, we conclude that strain YPD9-1T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus hexagrammi sp. nov. is proposed. The type strain of Paenibacillus hexagrammi is YPD9-1T (=KCTC 43424T =LMG 32988T).
