A bacterial strain designated 32A was isolated from the skin of an Anderson's salamander () and subjected to a comprehensive taxonomic study. The strain was Gram-stain-negative, rod-shaped, non-motile, oxidase- and urease-negative, and catalase-positive. 16S rRNA gene sequence comparisons placed the strain in the genus with highest sequence similarities to A4T-83 (95.2%), CB-286403 (95.1%) and E100 (94.9%). Genomic sequence analysis revealed a size of 5.3 Mbp, a G+C-content of 62.2 mol% and highest ANI values with (71.2%), (71.4%) and (69.5%). In the polyamine pattern, 1,3-diaminopropane and spermidine were predominant. The diagnostic diamino acid of the peptidoglycan was -diaminopimelic acid. The quinone system was composed of the major menaquinones MK-9 and MK-10. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, the unidentified aminolipid AL2, the unidentified phospholipid PL2 and the unidentified aminophospholipid APL1. The fatty acid profile contained major amounts of iso-C, iso-C, C and C ω9. In addition, C, C anteiso-C, summed feature 2 (C 3OH and/or iso-C I), and the hydroxylated fatty acids iso-C 3OH, iso-C 3OH and C 3-OH were detected. Physiologically, strain 32A is distinguishable from its next relatives. Based on phylogenetic, genomic, physiological and chemotaxonomic data, strain 32A represents a novel species of the genus for which we propose the name sp. nov. The type strain is 32A (=CCM 9141=LMG 32214).
一株编号为 32A 的细菌菌株从安氏蝾螈的皮肤中分离出来,并进行了全面的分类学研究。该菌株革兰氏阴性,杆状,不运动,氧化酶和脲酶阴性,过氧化氢酶阳性。16S rRNA 基因序列比较将该菌株置于属内,与 A4T-83(95.2%)、CB-286403(95.1%)和 E100(94.9%)的序列相似度最高。基因组序列分析显示其大小为 5.3 Mbp,G+C 含量为 62.2 mol%,与 (71.2%)、 (71.4%)和 (69.5%)的最高 ANI 值最高。在多胺图谱中,1,3-二氨基丙烷和腐胺占优势。肽聚糖的诊断二氨基酸是 -二氨基庚二酸。醌系统由主要的menaquinones MK-9 和 MK-10 组成。主要的极性脂是双磷脂酰甘油、磷脂酰甘油、磷脂酰乙醇胺、未鉴定的氨基脂 AL2、未鉴定的磷脂 PL2 和未鉴定的氨基磷脂 APL1。脂肪酸图谱含有大量的 iso-C 15:0、iso-C 17:0 3-OH、C 16:0 和 C 18:1 ω9c。此外,还检测到 C 14:0、C 15:0 anteiso-C 15:0、summed feature 2(C 3OH 和/或 iso-C I)和羟基脂肪酸 iso-C 3OH、iso-C 3OH 和 C 3-OH。在生理上,菌株 32A 与其近亲不同。基于系统发育、基因组、生理和化学分类学数据,菌株 32A 代表属内的一个新种,我们建议将其命名为 sp. nov. 模式菌株为 32A(=CCM 9141=LMG 32214)。
