sp. nov., isolated from isolated from estuary water.

A Gram-stain-negative, aerobic, non-motile and coccoid-, ovoid- or rod-shaped bacterial strain, designated KEM-5, was isolated from water sampled at an estuary environment on the Yellow Sea, Republic of Korea. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain KEM-5 fell within the clade comprising the type strains of species. Strain KEM-5 exhibited 16S rRNA gene sequence similarities of 97.01-97.66 % to the type strains of , and and of 94.18-96.95 % to the type strains of the other species. The genomicaverage nucleotide identity values of strain KEM-5 with a non-type strain (LAMA 915) of and SW-135 were 76.04 and 74.98 %, respectively. Mean DNA-DNA relatedness values between strain KEM-5 and the type strains of , and were 10-18 %. Strain KEM-5 contained Q-10 as the predominant ubiquinone and C 7, summed feature 3 (Cω7 and/or Cω6), C and Cω6 as the major fatty acids. The major polar lipids of strain KEM-5 were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. The DNA G+C content of strain KEM-5 was 62.4 mol%. Distinguishing phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain KEM-5 is separated from recognized species. On the basis of the data presented here, strain KEM-5 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KEM-5 (=KACC 19865=KCTC 62896=NBRC 113546).
