A Gram-stain-negative, non-motile bacterial strain, designated SW124, was isolated from a deep-sea sediment sample collected from the Indian Ocean. SW124 was aerobic and catalase-positive. The strain grew at 4-40 °C (optimum, 30 °C), at pH 5.0-8.6 (optimum, pH 7.0) and in the presence of 0.5-9.5 % (w/v) NaCl (optimum, 3.0%). The results of comparative analyses of the 16S rRNA gene sequence indicated that SW124 was grouped in the vicinity of the genus in the family . The quinone system contained menaquinone MK-7. The predominant cellular fatty acids were iso-C, iso-C 3-OH and summed feature 3 (comprising Cω7 and/or Cω6). SW124 contained phosphatidylethanolamine (PE) as the major polar lipid. The genomic DNA G+C content of SW124 was 41.7 mol%. On the basis of its phenotypic characteristics and phylogenetic data, we propose that strain SW124 (=CGMCC 1.16171=KCTC 82235) represents a novel species of a novel genus, with the name gen. nov., sp. nov.
一株革兰氏阴性、非运动性细菌菌株,被命名为 SW124,从印度洋深海沉积物样本中分离得到。SW124 为需氧菌,过氧化氢酶阳性。该菌株在 4-40°C(最适温度 30°C)、pH5.0-8.6(最适 pH7.0)和 0.5-9.5%(w/v)NaCl(最适 3.0%)的条件下生长。16S rRNA 基因序列的比较分析结果表明,SW124 与属的菌株在科内关系密切。醌类系统含有menaquinone MK-7。主要的细胞脂肪酸是 iso-C、iso-C 3-OH 和总和特征 3(包含 Cω7 和/或 Cω6)。SW124 含有磷脂酰乙醇胺(PE)作为主要的极性脂质。SW124 的基因组 DNA G+C 含量为 41.7 mol%。基于其表型特征和系统发育数据,我们建议菌株 SW124(=CGMCC 1.16171=KCTC 82235)代表一个新属的新型种,命名为 属,新种。
