Cells are irregularly shaped, nonbranching rods, 0.5–2.0 × 0.7–7.0 µm in size, chain-forming (up to 30 µm) Figure 266. Cells stain Gram-stain-positive. Anaerobic, nonsporeforming. Chemoorganotrophic, fermentative metabolism. Catalase-negative and oxidase-negative. Lactate is the main fermentation product.
