AnaerofilumRANK: GenusTAXONOMY: Bacteria -> Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Ruminococcaceae -> Anaerofilum OVERVIEW: Thin, straight rods, 0.2–0.6 µm in diameter and 3–6 µm in length, occurring singly or in pairs. Filaments up to 30 µm observed occasionally. Spores are not formed. Cell wall contains l-glycine, d-glutamate, l-lysine, and d-alanine. Serine forms linkage in interpeptide bridge. Sphaeroplasts are formed in the stationary phase. Some strains are motile. Obligate anaerobe. Strains of this organism are catalase negative. Mesophilic with temperature range for growth between 18 and 44°C. Chemoorganotrophic. Ferments mono- and disaccharides. Major end products of fermentation are lactate, acetate, ethanol, formate, 2,3-butanediol, and carbon dioxide. Sulfate is not reduced. Hydrogen and hydrogen sulfide are not produced. Found in anaerobic sewage sludge of municipal and industrial wastewater treatment plants. This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072]
