Abstract:
A Gram-stain-negative, yellow-pigmented, aerobic bacterial strain, designated LY02 T , was isolated from red tide seawater in Xiamen, Fujian Province, 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 LY02 T was related most closely to Altererythrobacter marensis MSW-14 T (97.2 % 16S rRNA gene sequence similarity), followed by Altererythrobacter ishigakiensis JPCCMB0017 T (97.1 %), Altererythrobacter epoxidivorans JCS350 T (97.1 %) and Altererythrobacter luteolus SW-109 T (97.0 %). The dominant fatty acids were C 18 : 1 ω7 c , C 17 : 1 ω6 c and summed feature 3 (comprising C 16 : 1 ω7 c and/or C 16 : 1 ω6 c ). DNA–DNA hybridization showed that strain LY02 T possessed low DNA–DNA relatedness to A. marensis MSW-14 T , A. ishigakiensis JPCCMB0017 T , A. epoxidivorans JCS350 T and A. luteolus SW-109 T (mean± sd of 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 gene sequence data, the novel strain most appropriately belongs to the genus Altererythrobacter , but can readily be distinguished from recognized species. The name Altererythrobacter xiamenensis sp. nov. is proposed (type strain LY02 T = CGMCC 1.12494 T = KCTC 32398 T = NBRC 109638 T ).
