Mobilicoccus caccae sp. nov., isolated from the faeces of the primate Rhinopithecus roxellanae

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).
