A Gram-stain-negative, facultative anaerobic, yellow-pigmented, rod-shaped, non-flagellum and non-motile bacterial strain,

designed C9-11T, was isolated from mangrove sediment in Zhangzhou, Fujian Province, China. Growth was observed at

temperatures from 15 to 37 _C (optimum 30 _C), at salinities from 0 to 4% (optimum 0.5–2 %) and at pH from 6 to 8 (optimum

7). Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain C9-11T was a member of the genus

Altererythrobacter. Strain C9-11T was related most closely to Altererythrobacter oceanensis Y2T (96.8% 16S rRNA gene

sequence similarity), followed by Altererythrobacter marinus H32T (96.5 %). The G+C content of the genomic DNA was 63.5 mol

%. The dominant fatty acids were C18 : 1!7c (41.6 %), C17 : 1!6c (15.4 %), 11-methyl C18 : 1!7c (8.1 %), summed feature 3

(comprising C16 : 1!7c and/or C16 : 1!6c 7.4 %) and C16 : 0 (6.2 %). The predominant respiratory quinone was ubiquinone-10 and

the major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and

sphingoglycolipid. According to its morphology, physiology, fatty acid composition and 16S rRNA gene sequence analysis,

strain C9-11Tbelongs to genus Altererythrobacter, but can readily be distinguished from recognized species. Strain C9-11T is

proposed as the type strain of a novel species of the genus Altererythrobacter, for which the name Altererythrobacter

mangrovi sp. nov (=MCCC 1K03311T=JCM 32056T) is proposed.
