Abstract

A novel bacterium, designated CAU 1612, was isolated from coastal sediment sampled in the Republic of Korea. Cells of the strain were Gram-stain-negative, rod-shaped and motile. Optimum growth occurred at 30 °C, at pH 7.0 and with 1.0 % (w/v) NaCl. Based on 16S rRNA gene sequences, phylogenetic analysis revealed that strain CAU 1612 belonged to the genus and showed highest similarity to '' JCM 33810 (98.5 %), followed by KCTC 32476 (97.7 %), KCTC 12842 (96.0 %), LMG 23452 (95.5 %), KCTC 52846 (95.5 %) and KCTC 12842 (95.4 %). The average nucleotide identity and digital DNA-DNA hybridization values of strain CAU 1612 were estimated to be 68.5-81.7 % and ≤23.7 %, respectively, to members of the genus . The DNA G+C content was 54.1 mol%. The major cellular fatty acids (>10 %) were C, C cyclo 8 and summed feature 8 (C 7 and/or C 6). The major menaquinone was Q-10 and the predominant polar lipids were phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. On the basis of taxonomic evidence, strain CAU 1612 represents a novel species, for which the name sp. nov. is proposed. The type strain is CAU 1612 (=KCTC 82427=MCCC 1K06082).

摘要

从韩国沿海沉积物中分离到一株新的细菌，命名为 CAU 1612。该菌株的细胞革兰氏阴性，呈杆状，可运动。最佳生长条件为 30°C、pH7.0 和 1.0%（w/v）NaCl。基于 16S rRNA 基因序列的系统发育分析表明，菌株 CAU 1612 属于属，与 '' JCM 33810（98.5%）的相似性最高，其次是 KCTC 32476（97.7%）、 KCTC 12842（96.0%）、 LMG 23452（95.5%）、 KCTC 52846（95.5%）和 KCTC 12842（95.4%）。菌株 CAU 1612 的平均核苷酸同一性和数字 DNA-DNA 杂交值估计分别为 68.5-81.7%和≤23.7%，与属内的其他成员相比。DNA G+C 含量为 54.1mol%。主要的细胞脂肪酸（>10%）为 C 、 C 环 8 和总和特征 8（C 7 和/或 C 6）。主要的menaquinone 为 Q-10，主要的极性脂为磷脂酰甲硫氨酸乙醇胺、磷脂酰乙醇胺和磷脂酰甘油。基于分类学证据，菌株 CAU 1612 代表一个新的物种，建议命名为 sp. nov.。模式菌株为 CAU 1612（=KCTC 82427=MCCC 1K06082）。
