Abstract:
A bacterial strain, designated SYD6 T , was isolated from a marine solar saltern on the coast of Weihai, Shandong Province, PR China. Cells of strain SYD6 T were rod-shaped, red, and approximately 5.0–9.0 μm in length and 0.4–0.6 μm in width. The strain was Gram-stain-negative, facultatively anaerobic, heterotrophic, catalase-positive and oxidase-negative. Growth occurred in 4–25 % (w/v) NaCl [with 2–15 % (w/v) MgCl 2 .6H 2 O also present], at 20–50 °C and pH 6.5–8.5. Optimal growth was observed at 37–42 °C, pH 7.5–8.0, with 6–8 % (w/v) NaCl [with 2–4 % (w/v) MgCl 2 .6H 2 O]. Nitrate was not reduced. Glucose, sucrose, maltose, fructose and ribose stimulated growth, but not glycerol, xylose or mannitol. The G+C content of the genomic DNA was 61.5 mol% (HPLC). The sole methyl naphthoquinone was MK-7 and the predominant cellular fatty acid s ( 〉 10 %) were iso-C 15 : 0 2-OH/C 16 : 1 ω7 c , iso-C 16 : 0 , C 18 : 1 ω7 c /C 18 : 1 ω6 c and C 18 : 1 ω7 c . The predominant polar lipids were phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and an unknown lipid. Phylogenetic analysis, based on 16S rRNA gene sequences, demonstrated that strain SYD6 T was affiliated with the phylum Bacteroidetes . The most closely related neighbours were species of the genus Salisaeta and strain SYD6 T had a 16S rRNA gene sequence similarity of 91.97 % with Salisaeta longa DSM 21114 T . On the basis of these phenotypic and phylogenetic data, strain SYD6 T represents a novel species of a new genus of the family Rhodothermaceae , for which the name Longimonas halophila gen. nov., sp. nov. is proposed. The type strain of the type species is SYD6 T ( = CICC 10838 T = KCTC 42399 T ).
