摘要
Strain CAU 1644T was isolated from sea sand at Ganghwa Island, Republic of Korea. The bacterium is aerobic, Gram-staining negative, yellow-colored, non-motile, catalase-positive, and rod-shaped. Cells of strain CAU 1644T grew at 20–40 °C and pH 6.0–10.0 with 0%–3.0% (w/v) NaCl. The 16S rRNA gene sequences of Altererythrobacter epoxidivorans CGMCC 1.7731T (identity, 98.5%) and A. xiamenensis CGMCC 1.12494T (98.0%) had the highest similarities to strain CAU 1644T. Strain CAU 1644T exhibits affiliation with the genus Altererythrobacter by phylogenetic trees based on the 16S rRNA gene and core-genome sequences. The predominant quinone was ubiquinone-10 (Q-10) and the major fatty acids were summed feature 8 (C18:1ω7c and/or C18:1ω6c) and summed feature 3 (C16:1ω7c and/or C16:1ω6c). The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of strain CAU 1644T were 77.6% and 20.1% with A. epoxidivorans CGMCC 1.7731T, respectively, and 77.4% and 21.0% with A. xiamenensis CGMCC 1.12494T. The G + C content is 62.5%. Based on phenotypic and genotypic analyses, strain CAU 1644T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter arenosus sp. nov., is proposed. The type strain is CAU 1644T (= KCTC 92082T = MCCC 1K07086T).
