A novel actinobacterium, designated YIM 101593T, was isolated from the faeces of a primate (Rhinopithecus roxellanae) living in Yunnan Wild Animal Park in Yunnan province, south-west China. The isolate was Gram-stain-positive, facultatively anaerobic, coccus-shaped, oxidase-negative and motile. The cell wall contained meso-diaminopimelic acid as its diagnostic diamino acid, and mannose, ribose, glucose, galactose and arabinose were detected as the main whole-cell sugars. The predominant menaquinone was MK-8(H2). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two glycolipids, three unidentified phospholipids and two unidentified lipids. The major fatty acids were C17 : 1ω8c, C15 : 0 and summed feature 4 (anteiso-C17 : 1 B and/or iso-C17 : 1 I). The DNA G+C content was 69.8 mol%. The 16S rRNA gene sequence similarity between strain YIM 101593T and Mobilicoccus pelagius was 97.9 %, and the two strains formed a distinct lineage stably on the basis of phylogenetic analysis. In addition, DNA-DNA relatedness between the two strains was 49.0±5.1 %. On the basis of chemotaxonomical and physiological characteristics and the phylogenetic analysis, strain YIM 101593T should be considered to represent a novel species of the genus Mobilicoccus, for which we propose the name Mobilicoccus caccae sp. nov., with the type strain YIM 101593T (=DSM 27611T=CCTCC AB 2013229T).
从中国西南部云南省云南野生动物园的一只滇金丝猴粪便中分离出一株新型放线菌,命名为YIM 101593T。该菌株革兰氏染色阳性,兼性厌氧,球形,氧化酶阴性,具运动性。细胞壁含有内消旋二氨基庚二酸作为其诊断性二氨基酸,主要全细胞糖检测到甘露糖、核糖、葡萄糖、半乳糖和阿拉伯糖。主要甲基萘醌为MK-8(H2)。极性脂为双磷脂酰甘油、磷脂酰甘油、磷脂酰肌醇、两种糖脂、三种未鉴定磷脂和两种未鉴定脂类。主要脂肪酸为C17 : 1ω8c、C15 : 0和特征性总和4(anteiso-C17 : 1 B和/或iso-C17 : 1 I)。DNA G+C含量为69.8 mol%。菌株YIM 101593T与海洋动球菌的16S rRNA基因序列相似性为97.9 %,基于系统发育分析,这两个菌株稳定地形成一个独特的分支。此外,两个菌株之间的DNA-DNA相关性为49.0±5.1 %。基于化学分类和生理特征以及系统发育分析,菌株YIM 101593T应被认为代表动球菌属的一个新物种,我们将其命名为食粪动球菌新种,模式菌株为YIM 101593T(=DSM 27611T=CCTCC AB 2013229T)。
