description: | Two moderately halophilic strains, designated SL013A34A2 T and SL013A24A, were isolated from oil-contaminated saline soil from Shengli Oilfield, eastern China. Cells were found to be Gram-staining negative, aerobic, rod-shaped with a single polar flagellum. The isolates were found to grow at 10–40 °C (optimum 35 °C), pH 6.0–9.0 (optimum pH 8.0), and NaCl concentrations of 0.5–18.0 % (w/v) (optimum 3.0–6.0 NaCl). The 16S rRNA gene sequence analysis indicated that the isolates belong to the genus Marinobacter . Strain SL013A34A2 T shares the highest 16S rRNA gene sequence similarities with strain SL013A24A (99.3 %), followed by M. hydrocarbonoclasticus CGMCC 1.7683 T (97.8 %), M. vinifirmus CGMCC 1.7265 T (97.8 %), and M. excellens KMM 3809 T (97.4 %), respectively, but low similarities (93.8–96.4 %) with type strains of the other numbers of genus Marinobacter . DNA–DNA relatedness values of strain SL013A34A2 T with strains SL013A24A, M. hydrocarbonoclasticus CGMCC 1.7683 T , M. vinifirmus CGMCC 1.7265 T and M. excellens KMM 3809 T were 88.7, 29.2, 33.4 and 29.4 %, respectively. The major fatty acids of strain SL013A34A2 T were identified as C 18:1 ω 9 c , C 16:0 , C 12:0 3-OH, C 12:0 , C 16:1 ω 9 c and 10-methyl C 18:0 . The major respiratory quinone of strain SL013A34A2 T was found to be ubiquinone-9, and its predominant polar lipids were identified as diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and unidentified glycolipid. The genomic DNA G + C content was found to be 56.1 mol %. Based on the phenotypic, genetic and chemotaxonomic characteristics, these two isolates are representatives of a novel species of the genus Marinobacter , for which the name Marinobacter shengliensis sp. nov. is proposed. The type strain is SL013A34A2 T (=LMG 27740 T = CGMCC 1.12758 T ). |
