Abstract

Abstract : A bacterial strain, designated HHTR 118 T, was isolated from a culture of the green alga Ulvaprolifera obtained from offshore seawater of Qingdao, Shandong Province, China. Cells of strain HHTR 118 T were rod-shaped and motile with a single flagellum, and approximately 0.3–0.4 µm wide and 0.8–1.4 µm long. The strain was Gram-stain-negative, strictly aerobic, catalase-negative and oxidase-positive. Optimal growth was observed at 30 °C, at pH 8.0 and with 1 % (w/v) NaCl. Nitrate was not reduced. Sucrose, sodium citrate and l -leucine stimulated growth, but not lactose, fructose, xylose, d -mannose, glucose, raffinose, rhamnose, ornithine or lysine. The DNA G+C content of strain HHTR 118 T calculated on the basis of the genome sequence was 64.9 mol% and the genome size is 4.6 Mbp. The major quinone was ubiquinone 10 and the predominant cellular fatty acids (>10 % of total fatty acids) were summed feature 8 (C18 : 1 ω6 c and/or C18 : 1 ω7 c ). The predominant polar lipids were phosphatidylglycerol, one unidentified phospholipid, two unidentified aminolipids and three unidentified polar lipids. Phylogenetic analysis, based on 16S rRNA gene sequences, demonstrated that strain HHTR 118 T was affiliated with the family Rhodospirillaceae . On the basis of the 16S rRNA gene sequence data as well as physiological and biochemical characteristics, we concluded that strain HHTR 118 T represents a novel species of a novel genus. We propose the name of Algihabitans albus gen. nov., sp. nov. for this novel species. The type strain of the novel species is strain HHTR 118 T (=KCTC 62395 T =MCCC 1K03486 T ).
