Phascolarctobacterium faeciumRANK: SpeciesTAXONOMY: Terrabacteria group -> Firmicutes -> Negativicutes -> Selenomonadales -> Acidaminococcaceae -> Phascolarctobacterium -> Phascolarctobacterium faecium OVERVIEW: Phascolarctobacterium faecium is a species of bacterium belonging to the family Acidaminococcaceae . Phascolarctobacterium faecium gen.nov., spec. nov. has been described for Gram-negatively staining, nonsporing, chemoorganotrophic, pleomorphic rods that were isolated from koala faeces. Propionate is the main end product of succinate fermentation and growth of satellite colonies occurs around colonies of succinate producing Escherichia coli cells. Phylogenetically, the novel genus groups within the Sporomusa branch of the Clostridium/Bacillus subphylum of Gram-positive bacteria and is a neighbor of Acidaminococcus fermentans. This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
