Helical rods 0.6–0.8 × 3–15 μm, usually occurring singly. Some cells are up to 32 µm in length. Motile by bipolar tufts of flagella. Do not form endospores. Gram negative. Anaerobic, having a strictly fermentative type of metabolism. Catalase negative or weakly positive. Oxidase negative. Do not hydrolyze esculin, gelatin, hippurate, or urea. Do not reduce nitrate. Lipase activity does not occur. Indole is not produced and meat is not digested. Ferment carbohydrates; produce succinic and acetic acids from glucose. May also produce traces of lactic and formic acids. Optimal temperature 37–44°C. Isolated from feces of dogs and cats. Pathogenic for humans, causing septicemia and/or diarrhea. Belongs to the class Gammaproteobacteria, order Aeromonadales, and family Succinivibrionaceae.
The mol% G + C of the DNA is: 39–44.
Type species: Anaerobiospirillum succiniciproducens Davis, Cleven, Brown and Balish 1976, 503.
