ABSTRACT
A novel cream-pigmented marine bacterium, designated strain YJ-T1-11T, was isolated from a tidal flat at Yeongjong-do, Republic of Korea. Cells were rod-shaped, non-motile, aerobic, Gram-reaction-negative, oxidase-positive and catalase-positive. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain YJ-T1-11T clustered with Gemmobacter fontiphilus JS43T (98.3â%) within the genus Gemmobacter and its closest neighbours were G.emmobacter aquatilis DSM 3857T (98.5â%), Gemmobacter aquaticus A1-9T (98.4â%), Gemmobacterlanyuensis Orc-4T (98.4â%), Gemmobacterfontiphilus JS43T (98.3â%), Gemmobactercaeni DCA-1T (98.2â%), Gemmobacternanjingensis Y12T (97.5â%) and Gemmobactertilapiae Ruye-53T (97.2â%). Average nucleotide identity values between the genome sequences of strain YJ-T1-11T and the related type strains ranged from 77.08 to 90.48â%. The predominant fatty acid of strain YJ-T1-11T was summed feature 8 (comprising C18ââ1ω7c and/or C18ââ1ω6c). The major isoprenoid quinone was Q-10 and the DNA G+C content was 65.6 mol%. The polar lipid profile consisted of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and three unidentified lipids. The DNA-DNA relatedness values between strain YJ-T1-11T and the type strains of the 12 phylogenetically related species of the genus Gemmobacter were 23.6-53.7â%. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain YJ-T1-11T is considered to represent a novel species of the genus Gemmobacter, for which the name Gemmobacter lutimaris sp. nov. is proposed. The type strain is YJ-T1-11T (=KCTC 62715T=JCM 32828T).
