A Gram-negative, rod-shaped and non-spore-forming bacterial strain, JM27(T), was isolated from a tidal flat of Dongtan Wetland, Chongming Island, China. The strain formed smooth yellow colonies on R2A plates. Growth occurred at 10-37 degrees C (optimum, 30-37 degrees C), at pH 6.0-10.0 (optimum, pH 7.0-9.0) and in the presence of 0-1% NaCl (optimum, 0 %). Catalase test was positive and oxidase test was negative. Ubiquinone 10 (010) was the major respiratory quinone. C-18 : 1 omega 7c and C-17 : 1 omega 6c were the most abundant fatty acids. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids. The DNA G + C content of strain JM27(T) was 66.4 mol%. The 16S rRNA gene sequence of the isolate showed highest similarity to that of Altererythrobacter marinus H32(T) (96.4%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Altererythrobacter of the family Erythrobacteraceae of the class Alphaproteobacteria. On the basis of phylogenetic analysis, whole-cell fatty acids, polar lipid compositions, and biochemical and physiological characteristics, strain JM27(T) is proposed to represent a novel species of the genus Altererythrobacter for which the name Altererythrobacter dongtanensis sp. nov. is proposed. The type strain is JM27(T) (=KCTC 22672(T) = CCTCC AB 209199(T)).
