Clostridium argentinense
Clostridium argentinense is an anaerobic, motile, gram-positive bacterium. Some bacilli now identified as Cl. argentinense were previously classified as either Cl. subterminale, Cl. hastiforme, or Cl. botulinum toxin group G, respectively. Like Cl. botulinum, Cl. argentinense produces botulin, a neurotoxin that causes botulism in susceptible mammals. Among this proteolytic species' products are acetic acid, butyric acid, isobutyric acid, isovaleric acid, and hydrogen sulfide. Cl. argentinense is also asaccharolytic  (i.e., unable to metabolize carbohydrates). References
