Abstract

A Gram-stain-negative, aerobic, orange-coloured, rod-shaped and non-motile bacterial strain, PAMC 29362, was isolated from an Antarctic lichen, . Phylogenetic and phylogenomic analyses indicated that strain PAMC 29362 belongs to the genus and was most closely related to (97.0% of 16S rRNA gene similarity), (96.3 %) (95.3 %) and (95.2 %). Genomic relatedness analyses showed that strain PAMC 29362 is clearly distinguished from type strains of the genus based on values of average nucleotide identity (<74.3 %) and digital DNA-DNA hybridization (<20.4 %). The genomic DNA G+C content of PAMC 29362 was 65.5 %. The major fatty acids (>10 %) were summed feature 8 (C 7; 38.5 %) and summed feature 3 (C 7 and/or C 6; 31.5 %). The major respiratory quinone was Q-10. Based on the results of phylogenetic, genome-based relatedness and physiological analyses, strain PAMC 29362 is proposed to represent a novel species of the genus , with the name sp. nov. The type strain is PAMC 29362 (=KCTC 82 578=JCM 34545).

摘要

一株革兰氏阴性、需氧、橙色、杆状、非运动的细菌菌株 PAMC 29362 从一种南极地衣中分离出来。基于 16S rRNA 基因相似性（97.0%）的系统发育和系统基因组分析表明，该菌株 PAMC 29362 属于属，与（96.3%）、（95.3%）和（95.2%）最为密切相关。基因组相关性分析表明，菌株 PAMC 29362 与属的模式菌株在平均核苷酸同一性（<74.3%）和数字 DNA-DNA 杂交（<20.4%）值上明显不同。PAMC 29362 的基因组 DNA G+C 含量为 65.5%。主要脂肪酸（>10%）为 C7 总和特征 8（38.5%）和 C7 和/或 C6 总和特征 3（31.5%）。主要呼吸醌为 Q-10。基于系统发育、基于基因组的相关性和生理分析的结果，建议菌株 PAMC 29362 代表属的一个新种，命名为 sp. nov.。其模式菌株为 PAMC 29362（=KCTC 82578=JCM 34545）。
