sp. nov., a marine bacterium isolated from a tidal flat and reclassification of , and comb. nov., comb. nov. and comb. nov.

A yellow-coloured bacterium, designated strain JGD-16, was isolated from a tidal flat in Janggu-do, Garorim Bay, Taean-gun, Chungcheongbuk-do, Republic of Korea. Cells were Gram-stain-negative, aerobic, non-flagellated and short ovoid to coccoid-shaped. Growth was observed at 10-37 °C (optimum, 30 °C), pH 6.0-9.0 (pH 8.0) and with 1-5% (w/v) NaCl (2%). Results of 16S rRNA gene sequence analysis indicated that strain JGD-16 was closely related to LY02 (97.1 %), O30 (96.3 %), JPCCMB0017 (95.8 %), JCS350 (95.7 %) and BPTF-M16 (95.3%). Phylogenomic analysis using the maximum-likelihood algorithm showed that strain JGD-16 formed a clade with the genus . The genomic DNA G+C content was 57.8 mol%. The predominant respiratory quinone was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, a sphingoglycolipid, an unidentified glycolipid and an unidentified lipid. The major fatty acids were C 7 (31.5 %) and C 6 (19.6 %). On the basis of its phylogenomic, physiological and chemotaxonomical characteristics, strain JGD-16 represents a novel species within the genus , for which the name JGD-16sp. nov. is proposed. The type strain is JGD-16 (=KCTC 72632=KACC 21405=JCM 33750). We also propose the reclassification of as comb. nov., as comb. nov. and as comb. nov.
