Marinobacter halodurans sp. nov., a halophilic bacterium isolated from sediment of a salt flat

A Gram-staining-negative, aerobic, cream-coloured, marine bacterium, with rod-shaped cells, designated strain YJ-S3-2 , was isolated from salt flat sediment of Yongyu-do, Republic of Korea. YJ-S3-2 grew at pH 5.0-9.0 (optimum pH 7.0), 4-45 °C (optimum 30 °C) and with 1-18 % (w/v) NaCl (optimum 6 %). The results of 16S rRNA gene sequence analysis indicated that YJ-S3-2 was closely related to SS011B1-4 (97.0 %) followed by, ' ' D15-8W (96.7 %), 50-11 (96.7 %), DSMZ 179240 (96.5 %) and T17 (96.5 %). The average nucleotide identity (ANI) and the genome to genome distance calculator (GGDC) estimate values between YJ-S3-2 and related type strains were 73.7-79.8 and 19.9-22.5 %, and also 73.5 and 20.7 % with . YJ-S3-2 was characterized as having Q-9 as the predominant respiratory quinone and the principal fatty acids (>10 %) were C (22.3 %), summed feature 9 (C iso ω9 /C 10-methyl, 13.8 %) and 3 (C ω7 C1 ω6 11.9 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and two unidentified phospholipids. The DNA G+C content of YJ-S3-2 is 60.9 mol%. On the basis of the polyphasic taxonomic evidence presented in this study, YJ-S3-2 should be classified as representing a novel species within the genus , for which name sp. nov. is proposed, with the type strain YJ-S3-2 (=KACC 19883 =KCTC 62937 =JCM 33109 ).
