Description

Strains belonging to the sole species of the genus Faecalibacterium are strictly anaerobic bacteria, with a fermentative type of metabolism. Butyrate, D-lactate and formate are products of glucose fermentation. Acetate is utilized by all strains. Strains Fusobacterium prausnitzii ATCC 27768T and 27766, A2-165 and L2-6 are able to hydrolyze fructose, fructose-oligosaccharides, starch and inulin. In pure culture, cells appear as straight rods. No physiological information has been determined for the genus in situ in activated sludge.
