Abstract

Strain CAU 1644^T 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 1644^T 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 1.7731^T (identity, 98.5%) and A. xiamenensis CGMCC 1.12494^T (98.0%) had the highest similarities to strain CAU 1644^T. Strain CAU 1644^T 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 (C_18:1ω7c and/or C_18:1ω6c) and summed feature 3 (C_16:1ω7c and/or C_16:1ω6c). The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of strain CAU 1644^T were 77.6% and 20.1% with A. epoxidivorans CGMCC 1.7731^T, respectively, and 77.4% and 21.0% with A. xiamenensis CGMCC 1.12494^T. The G + C content is 62.5%. Based on phenotypic and genotypic analyses, strain CAU 1644^T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter arenosus sp. nov., is proposed. The type strain is CAU 1644^T (= KCTC 92082^T = MCCC 1K07086^T).

从海洋沉积物中分离出的新厌氧菌（Altererythrobacter arenosus sp.

CAU 1644T 菌株是从大韩民国江华岛的海沙中分离出来的。该细菌好氧、革兰氏染色阴性、黄色、无运动性、催化酶阳性、杆状。CAU 1644T 菌株在 20-40 °C、pH 值 6.0-10.0 和 0%-3.0%（w/v）NaCl 条件下生长。与 CAU 1644T 的 16S rRNA 基因序列相似度最高的是 Altererythrobacter epoxidivorans CGMCC 1.7731T（相似度为 98.5%）和 A. xiamenensis CGMCC 1.12494T（相似度为 98.0%）。基于 16S rRNA 基因和核心基因组序列的系统发生树显示，菌株 CAU 1644T 属于赤霉菌属。主要的醌为泛醌-10（Q-10），主要脂肪酸为总特征 8（C18:1ω7c 和/或 C18:1ω6c）和总特征 3（C16:1ω7c 和/或 C16:1ω6c）。CAU 1644T 与 A. epoxidivorans CGMCC 1.7731T 的平均核苷酸同一性（ANI）和数字 DNA-DNA 杂交（dDDH）值分别为 77.6% 和 20.1%，与 A. xiamenensis CGMCC 1.12494T 的平均核苷酸同一性（ANI）和数字 DNA-DNA 杂交（dDDH）值分别为 77.4% 和 21.0%。G + C 含量为 62.5%。根据表型和基因型分析，CAU 1644T 菌株代表了赤霉菌属的一个新菌种，拟命名为 Altererythrobacter arenosus sp.模式菌株为 CAU 1644T（= KCTC 92082T = MCCC 1K07086T）。
