A Gram-negative, rod-shaped and slightly halophilic bacterium, strain XY-R17T, was isolated from the surface sediment of Mai Po Inner Deep Bay Ramsar Site birdwatch in Hong Kong. The 16S rRNA gene sequence of strain XY-R17T exhibited 96.5 % similarity to that of the type strain of Altererythrobacter atlanticus. Optimal growth occurred at pH 7.0-7.5, 3-8 % (w/v) NaCl and at 30 °C. The major respiratory quinone was ubiquinone-10. The principal fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), 11-methyl C18 : 1ω7c and C17 : 1ω6c .The polar lipid profile consisted of the major compounds sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and two unknown lipids. The DNA G+C content was 64.7 mol%. Based on its phenotypic properties, chemotaxonomic characteristics and phylogenetic distinctiveness, strain XY-R17T should be designated as a novel species of the genus Altererythrobacter. Therefore, the name Altererythrobacter salegens sp. nov. (type strain XY-R17T=KCTC 52267T=MCCC 1K01500T) is proposed.
