A novel actinobacterial strain, Gram-positive, anaerobic, non-motile, and rod-shaped, designated KGMB02528^T, was isolated from healthy human feces. Cells of strain KGMB02528^T grew optimally at pH 7.0 and 37 °C and in the presence of 0% (w/v) NaCl. Based on 16S rRNA gene sequence similarity, strain KGMB04489^T belonged to the genus Collinsella and was most closely related to Collinsella aerofaciens DSM 17552^T (95.8%). The DNA G + C content was 58.0 mol%. The major cellular fatty acids (> 10%) were C_16:0 DMA, C_16:0 ALDE, C_14:0 DMA, and C_12:0. The predominant end product of fermentation was acetic acid. The cell wall peptidoglycan of strain KGMB02528^T contained alanine, glutamic acid, and lysine, while diaminopimelic acid was not detected. The polar lipids were composed of two unidentified phospholipids and unidentified nine glycolipids. Based on the phenotypic, chemotaxonomic, and phylogenetic properties, strain KGMB02528^T represents a novel species of the genus Collinsella, for which the name Collinsella acetigenes sp. nov. is proposed. The type strain is Collinsella acetigenes KGMB02528^T (= KCTC 15847^T = CCUG 73987^T). The description of the genus Collinsella is emended to accommodate the new species.

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of Collinsella acetigenes KGMB02528^T is MT117838. The whole-genome shotgun BioProject number is PRJNA623694 with the accession number JABBCP000000000.

从健康人类粪便中分离出一种新的放线菌菌株，革兰氏阳性、厌氧、非运动性和杆状，命名为 KGMB02528 ^T。菌株 KGMB02528 ^{T 的}细胞在 pH 7.0 和 37°C 以及 0% (w/v) NaCl 存在下最佳生长。基于16S rRNA基因的序列相似性，应变KGMB04489 ^Ť属于属柯林斯并最密切相关的柯林斯aerofaciens DSM 17552 ^Ť（95.8％）。DNA G + C 含量为 58.0 mol%。主要的细胞脂肪酸 (> 10%) 是 C _16:0 DMA、C _16:0 ALDE、C _14:0 DMA 和 C _12:0. 发酵的主要终产物是乙酸。菌株KGMB02528 ^T的细胞壁肽聚糖含有丙氨酸、谷氨酸和赖氨酸，未检出二氨基庚二酸。极性脂质由两种未鉴定的磷脂和九种未鉴定的糖脂组成。基于表型，化学分类，和系统发育性能，应变KGMB02528 ^Ť表示属的一个新种柯林斯，为此，名称柯林斯acetigenes藻。十一月 被提议。类型菌株是Collinsella acetigenes KGMB02528 ^T (= KCTC 15847 ^T  = CCUG 73987 ^T )。属的描述柯林斯是仔细的校勘，以适应新的物种。
