Abstract

Strain ZH6 is a Gram-stain-negative, rod-shaped, aerobic bacterium isolated from manganese mine soil. Strain ZH6 had highest 16S rRNA gene sequence similarities to YX-36 (96.9 %) and NH7-4 (96.8 %). The genome size of strain ZH6 was 4.61 Mb with a DNA G+C content of 44.0 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between strain ZH6 and DSM 26809 were 70.6 and 19.2 %, respectively. Strain ZH6 had menaquinone-7 as a major quinone and main cellular fatty acids of iso-C, iso-C 3-OH and summed feature 3 (Cω7 and/or Cω6). The polar lipids of strain ZH6 were a phosphatidylethanolamine, an unidentified glycolipid, an unidentified phospholipid, three unidentified aminophospholipids and four unidentified lipids. Based on the phenotypic, chemotaxonomic and phylogenetic results, strain ZH6 represents a novel species of the genus , for which the name sp. nov., is proposed. The type strain is ZH6 (=CCTCC AB 2018373=KCTC 72075).

摘要

菌株 ZH6 是一株革兰氏阴性、杆状、需氧细菌,从锰矿土壤中分离得到。菌株 ZH6 与 YX-36(96.9%)和 NH7-4(96.8%)的 16S rRNA 基因序列相似度最高。菌株 ZH6 的基因组大小为 4.61Mb,GC 含量为 44.0mol%。菌株 ZH6 与 DSM 26809 之间的平均核苷酸同一性和数字 DNA-DNA 杂交值分别为 70.6%和 19.2%。菌株 ZH6 以menaquinone-7 作为主要醌类,以 iso-C、iso-C 3-OH 和 sumed feature 3(Cω7 和/或 Cω6)作为主要细胞脂肪酸。菌株 ZH6 的极性脂质包括磷脂酰乙醇胺、一种未鉴定的糖脂、一种未鉴定的磷脂、三种未鉴定的氨基磷脂和四种未鉴定的脂质。基于表型、化学分类和系统发育结果,菌株 ZH6 代表了一个新的属种,提议将其命名为 sp. nov.,其模式菌株为 ZH6(=CCTCC AB 2018373=KCTC 72075)。
