摘要:A Gram-stain-negative, rod-shaped, non-motile and facultatively anaerobic bacterium, designated AM505(T), was isolated from Shuangdao Bay in Weihai, China. Cells of strain AM505(T) were 0.4-0.8 pm wide, 1.3-3.3 pm long, catalase-positive and oxidase-positive. Strain AM505(T) was tolerant to moderate salt conditions. Growth occurred at 4-40 degrees C (optimum, 28-33 degrees C), pH 6.5-9.5 (pH 7.5-8.0) and with 0.5-9.0 % NaCl (w/v; 2.0-4.0 %). A phylogenetic analysis of the 16S rRNA gene indicated that strain AM505(T) was a member of the genus Pararhodobacter within the family Rhodobacteraceae. The most closely related neighbour was Pararhodobacter aggregans DSM 18938(T) (97.6 %). The average nucleotide identity value between AM505(T) and P. aggregans DSM 18938(T) was 75.3 %. The major respiratory quinone of strain AM505(T) was ubiquinone-10 and the predominant cellular fatty acids (>10%) were summed feature 8 (consisting of C-18:1 omega 7c and/or C-18:1 omega 6c), 11-methyl C-18:1 omega 7c and C-18:0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and an unidentified aminolipid. The genomic DNA G+C content was 63.0 mol%. Based on our polyphasic taxonomic study, strain AM505(T) should be a novel species in the genus Pararhodobacter, for which the name Pararhodobacter oceanensis sp. nov. is proposed. The type strain is AM505(T) (=KCTC 62407(T) =MCCC 1H00289(T)).
