Abstract

A strictly anaerobic, Gram-stain-negative rod-shaped bacterium, designated A1-XYC3, was isolated from the faeces of an alpaca (). On the basis of the results of a comparative 16S rRNA gene sequence analysis, the isolate was assigned to the genus with the highest sequence similarities to DSM 2767 (96.8 %), P7 (96.3 %) and JW/YJL-B3 (96.1 %). The average nucleotide identity between A1-XYC3, and . was 77.4, 76.1 and 76.6 %, respectively. The predominant components of the cellular fatty acids of A1-XYC3 were C, C and summed feature 10, containing C/C cyclo. The DNA G+C content was 32.4 mol%. On the basis of biochemical, phylogenetic, genotypic and chemotaxonomic criteria, this isolate represents a novel species within for which the name sp. nov. is proposed. The type strain of this species is strain A1-XYC3 (=CCM 9376=NRRL B-65691).

摘要

一株严格厌氧、革兰氏阴性、杆状的细菌，被命名为 A1-XYC3，从一只羊驼的粪便中分离得到。基于 16S rRNA 基因序列分析的结果，该分离株被归属于属，与 DSM 2767（96.8%）、P7（96.3%）和 JW/YJL-B3（96.1%）的序列相似度最高。A1-XYC3 与. 之间的平均核苷酸同一性分别为 77.4%、76.1%和 76.6%。A1-XYC3 的细胞脂肪酸的主要成分是 C16:0、C18:1ω7c 和 summed feature 10，含有 C/C 环。DNA G+C 含量为 32.4 mol%。基于生化、系统发育、基因型和化学分类学标准，该分离株代表了属中的一个新种，建议将其命名为. 新种。该种的模式菌株为 A1-XYC3 菌株（=CCM 9376=NRRL B-65691）。
