Abstract

A study of the faecal microbiome in three healthy female rhesus macaques revealed the presence of a novel obligately anaerobic, chemoorganoheterotrophic, non-sporing, coccoid, non-motile, Gram-stain-positive bacterial species. Three strains of this species, designated as M108, M916-1/1, and M919-2/1, were non-haemolytic, HS-positive, catalase-positive, bile- and NaCl-sensitive and required peptone for growth. Strains also were asaccharolytic, able to utilize sulfite, thiosulfate and elemental sulfur as electron acceptors, and produced acetic and butyric acids as metabolic end-products. Strain M108 is characterized by the prevalence of C, C and Cω9 dimethyl acetal among the cellular fatty acids, and the presence of MK-10 menaquinone. The DNA G+C content was found to be 51 mol%. Phylogenetic analysis of partial 16S rRNA gene sequences of strains M108, M916-1/1 and M919-2/1 placed these strains into the genus (family ). On the basis of phenotypic and genotypic properties we conclude that these strains represent a novel bacterial species for which the name sp. nov. is proposed. The type strain is M108 (=DSM 100347=VKM B-2932).
