Clostridium

Patent Pending Clostridium is a genus of Gram-positive bacteria belonging to the Firmicutes. They are obligate anaerobes capable of producing endospores.[1][2] Individual cells are rod-shaped, which gives them their name, from the Greek kloster (κλωστήρ) or spindle. These characteristics traditionally defined the genus; but many species originally classified as Clostridium have been reclassified in other genera.
