Genotypic Description:
Phenotypic Characteristics: Gram-negative obligately anaerobic cocco-bacilli to short bacilli. Strains are asaccharolytic and generally biochemically unreactive although hydrogen sulphide is produced. Acetic and isovaleric acids and minor to trace amounts of propionic isobutyric succinic and phenyl-acetic acids are produced as end products of fermentation. The G + C content of the DNA of the type strain is 59 mol %.
Cultivability: After 7-day incubation on Fastidious Anaerobe Agar plates (incorporating 5 % horse blood) strains of this species form circular entire high convex colonies around 1 mm in diameter.
