Abstract

A Gram-negative, motile, rod-shaped aerobic and alkalogenic bacterium, designated as strain YLCF04^T, was isolated from chicken faeces. Its growth was optimal at 28 °C (range, 10-40 °C), pH 8 (range, pH 6-9) and in 1 % (w/v) NaCl (range, 0-10 %). It was classified to the genus Paenalcaligenes and was most closely related to Paenalcaligenes hominis CCUG 53761A^T (97.5 % similarity) based on 16S rRNA gene sequence analysis. Average nucleotide identity and digital DNA-DNA hybridization values between YLCF04^T and P. hominis CCUG 53761A^T were 76.3 and 18.2 %, respectively. Strain YLCF04^T has a genome size of 2.7 Mb with DNA G+C content of 46.3 mol%. Based on its phylogenetic, genomic, phenotypic and biochemical characteristics, strain YLCF04^T represents a novel species of the genus Paenalcaligenes, for which the name Paenalcaligenes faecalis sp. nov. is proposed. The type strain is YLCF04^T (=CCTCC AB 2022359^T= KCTC 92789^T).

从鸡粪中分离出的一种新的阿尔卡利氏菌（Paenalcaligenes faecalis sp.

从鸡粪中分离出了一种革兰氏阴性、能动、棒状的需氧和碱性细菌，命名为 YLCF04T 菌株。它在 28 °C（范围为 10-40°C）、pH 值为 8（范围为 pH 值 6-9）和 1%（重量/体积）NaCl（范围为 0-10%）条件下生长最理想。根据 16S rRNA 基因序列分析，它被归类为 Paenalcaligenes 属，与 Paenalcaligenes hominis CCUG 53761AT 的亲缘关系最密切（相似度为 97.5%）。YLCF04T 与 P. hominis CCUG 53761AT 的平均核苷酸相同度和数字 DNA-DNA 杂交值分别为 76.3 % 和 18.2 %。菌株 YLCF04T 的基因组大小为 2.7 Mb，DNA G+C 含量为 46.3 mol%。根据其系统发育、基因组、表型和生化特征，菌株 YLCF04T 代表了 Paenalcaligenes 属的一个新物种，并将其命名为 Paenalcaligenes faecalis sp.模式菌株为 YLCF04T（=CCTCC AB 2022359T= KCTC 92789T）。

期刊介绍： Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names. The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including: Identification, characterisation and culture preservation Microbial evolution and biodiversity Molecular environmental work with strong taxonomic or evolutionary content Nomenclature Taxonomy and phylogenetics.
