TAXONOMY: Bacteria -> Terrabacteria group -> Firmicutes -> Erysipelotrichia -> Erysipelotrichales -> Erysipelotrichaceae -> Catenibacterium
Cells occur in tangled chains. Gram-stain-positive and obligately anaerobic. Spores are absent. Fermentation products of glucose are acetic, lactic, butyric and isobutyric acids. Cell wall contains an A1c-type peptidoglycan with an (l-Ala)–d-Glu–m-Dpm peptide subunit. The genus Catenibacterium is a member of the Clostridium subphylum of the Gram-positive bacteria and exhibits a close phylogenetic association with Lactobacillus catenaformis and Lactobacillus vitulinus.
DNA G+C content (mol%): 36–39 (HPLC).
Type species: Catenibacterium mitsuokai
This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072]
