ABSTRACT
A Gram-staining-negative, aerobic, cream-coloured, marine bacterium, with rod-shaped cells, designated strain YJ-S3-2T, was isolated from salt flat sediment of Yongyu-do, Republic of Korea. YJ-S3-2T grew at pH 5.0-9.0 (optimum pH 7.0), 4-45 °C (optimum 30 °C) and with 1-18â% (w/v) NaCl (optimum 6â%). The results of 16S rRNA gene sequence analysis indicated that YJ-S3-2T was closely related to Marinobacter segnicrescens SS011B1-4T (97.0â%) followed by, 'Marinobacter nanhaiticus' D15-8W (96.7â%), Marinobacter bryozoorum 50-11T (96.7â%), Marinobacter koreensis DSMZ 179240T T (96.5â%) and Marinobacter bohaiensis T17T (96.5â%). The average nucleotide identity (ANI) and the genome to genome distance calculator (GGDC) estimate values between YJ-S3-2T and related type strains were 73.7-79.8 and 19.9-22.5â%, and also 73.5 and 20.7â% with Marinobacter hydrocarbonoclasticus. YJ-S3-2T was characterized as having Q-9 as the predominant respiratory quinone and the principal fatty acids (>10â%) were C16ââ0 (22.3â%), summed feature 9 (C17ââ1iso ω9c/C16ââ0 10-methyl, 13.8â%) and 3 (C16ââ1ω7c/C16ââ1ω6c, 11.9â%). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and two unidentified phospholipids. The DNA G+C content of YJ-S3-2T is 60.9 mol%. On the basis of the polyphasic taxonomic evidence presented in this study, YJ-S3-2T should be classified as representing a novel species within the genus Marinobacter, for which name Marinobacter halodurans sp. nov. is proposed, with the type strain YJ-S3-2T (=KACC 19883T=KCTC 62937T=JCM 33109T).
