sp. nov., a marine bacterium isolated from surface seawater of the Yellow Sea, and proposal of gen. nov., comb. nov. and comb. nov. Free

Abstract

A bacterial strain designated RZ02 was isolated from surface seawater collected from the Yellow Sea in PR China and characterized by polyphasic taxonomy. Cells of strain RZ02 were Gram-stain-negative, aerobic, non-motile, catalase- and oxidase-positive rods forming ochre-pigmented colonies. Growth occurred at 7–36 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0) and with 1–5 % (optimum, 2 %) NaCl. The major cellular fatty acids (>10 %) of strain RZ02 were summed feature 8 (C 6 and/or C 7), summed feature 3 (C 7 and/or C 6) and C. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol and sphingoglycolipid. The genome size of strain RZ02 was 2.79 Mbp with a G+C content of 55.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RZ02 was mostly related to SW-109 and HDW-31 (97.3 and 97.1% sequence similarity, respectively), and formed a phyletic lineage with members of the genus . The phylogenetic analysis based on the up-to-date bacterial core gene sequences confirmed that strain RZ02 clustered within the genus . The average nucleotide identity and DNA–DNA hybridization values between strain RZ02 and SW-109 and HDW-31 were 72.8 and 72.9 % and 18.7 and 18.5%, respectively. Based on these evidences, strain RZ02 is proposed to represent a novel species of the genus under the name sp. nov. The type strain is RZ02 (=KCTC 62828=MCCC 1K04521). In addition, based on the results of whole genome analyses, proposals of gen. nov., comb. nov. and comb. nov. are also included.
