A Gram-stain-negative, yellow-pigmented, aerobic bacterial strain, designated LY02T, was isolated from red tide seawater in Xiamen, Fujian Province of China. Growth was observed at temperatures from 4 to 44 °C, at salinities from 0 to 9 % and at pH from 6 to 10. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the isolate was a member of the genus Altererythrobacter, which belongs to the family Erythrobacteraceae. Strain LY02T was most closely related to Altererythrobacter marensis MSW-14T (97.2 % sequence similarity), followed by Altererythrobacter ishigakiensis JPCCMB0017T (97.1 %), Altererythrobacter epoxidivorans JCS350T (97.1 %) and Altererythrobacter luteolus SW-109T (97.0 %). The dominant fatty acids were C18:1 ω7c (61.6 %), C17:1 ω6c (10.0 %) and Summed Feature 3 (comprising C16:1 ω7c and/or C16:1 ω6c, 9.6 %), which accounted for 81.3 %. DNA-DNA hybridization showed that strain LY02T with A. marensis MSW-14T, A. ishigakiensis JPCCMB0017T, A. epoxidivorans JCS350T and A. luteolus SW-109T possessed a low DNA-DNA relatedness (33.2±1.3 %, 32.1±1.0 %, 26.7±0.7 % and 25.2±1.1 %, respectively). The G+C content of the chromosomal DNA was 61.2 mol%. The predominant respiratory quinone was ubiquinone-10 (Q-10). According to its morphology, physiology, fatty acid composition and 16S rRNA sequence data, the novel strain most appropriately belongs to the genus Altererythrobacter, but can readily be distinguished from known Altererythrobacter species. The name Altererythrobacter xiamenensis sp. nov. is proposed (type strain LY02T= CGMCC 1.12494T= KCTC 32398T= NBRC 109638T).
