“…In addition, members of this genus have been reported to be marine polycyclic aromatic hydrocarbon degraders (Cui et al , 2008; Dastgheib et al , 2012; Melcher et al , 2002). At the time of writing, the genus Marinobacter consists of 34 species (http://www.bacterio.net/marinobacter.html) from various environments including salt lakes (Aguilera et al , 2009; Bagheri et al , 2013), saline soil (Gu et al , 2007; Martín et al , 2003), salterns (Qu et al , 2011; Wang et al , 2009; Yoon et al , 2007), brine samples of a salt concentrator (Kharroub et al , 2011), seawater (Antunes et al , 2007; Gauthier et al , 1992; Kaeppel et al , 2012; Roh et al , 2008; Shivaji et al , 2005; Xu et al , 2008; Yoon et al , 2003, 2004; Zhuang et al , 2009), sea sediment (Gao et al , 2013; Gorshkova et al , 2003; Guo et al , 2007; Huo et al , 2008; Montes et al , 2008; Romanenko et al , 2005), sea sand (Kim et al , 2006), marine animals (Green et al , 2006; Lee et al , 2012), coastal hydrothermal sediment (Handley et al , 2009), coastal hot springs (Shieh et al , 2003), wastewater (Liebgott et al , 2006), an oil-producing well (Huu et al , 1999), Arctic sea-ice (Zhang et al , 2008) and sandy sediment of the Antarctic (Liu et al , 2012). The diverse origins of members of the genus suggest that they are widely distributed and may play important roles in the environment, such as the degradation of aromatic hydrocarbons.…”

A Gram-staining-negative bacterium, strain XCD-X12 T , was isolated from Xiaochaidan Lake, a salt lake (salinity 9.9 %, w/w) in Qaidam basin, Qinghai Province, China. Its taxonomic position was determined by using a polyphasic approach. Cells of strain XCD-X12T were nonspore-forming rods, 0.4-0.7 mm wide, 2.1-3.2 mm long and motile with a single polar flagellum. T was 34¡5 %. Based on these data, it is concluded that strain XCD-X12

An aerobic, Gram-stain-negative bacterium, designated CLL7-20T, was isolated from a marine sediment sample from offshore of Changyi, Shandong Province, China. Cells of strain CLL7-20T were rod-shaped, motile with one or more polar flagella, and grew optimally at pH 7.0, at 28 °C and with 3 % (w/v) NaCl. The principal fatty acids of strain CLL7-20T were C16 : 0 and summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c). The main polar lipids of strain CLL7-20T were phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and an unidentified aminolipid (AL). Strain CLL7-20T contained Q-9 as the major respiratory quinone. The G+C content of its genomic DNA was 56.2 mol%. Phylogenetically, strain CLL7-20T branched within the genus Marinobacter , with M. daqiaonensis YCSA40T being its closest phylogenetic relative (96.7 % 16S rRNA gene sequence similarity), followed by M. sediminum R65T (96.6 %). Average nucleotide identity and in silico DNA–DNA hybridization values between strain CLL7-20T and the closest related reference strains were 73.2% and 19.8 %, respectively. On the basis of its phenotypic, phylogenetic and chemotaxonomic characteristics, we suggest that strain CLL7-20T (=MCCC 1A14855T=KCTC 72664T) is the type strain of a novel species in the genus Marinobacter , for which the name Marinobacter changyiensis sp. nov. is proposed. Based on the genomic analysis, siderophore genes were found from strain CLL7-20T, which indicate its potential as a promising alternative to chemical fertilizers in iron-limitated environments such as saline soils.

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 C18:1 ω9c, C16:0, C12:03-OH, C12:0, C16:1 ω9c and 10-methyl C18:0. 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)).
