| − | '''''Clostridium botulinum''''' is the name of a group of [[bacteria]] commonly found in soil. These rod-shaped organisms grow best in low oxygen conditions. The bacteria form spores which allow them to survive in a dormant state until exposed to conditions that can support their growth. ''Clostridium botulinum'' is the bacterium that produces [[botulinum toxin|botulin]], the nerve [[toxin]] that causes [[botulism]]. Botulin is one of the most powerful toxins in the world; the lethal dose for a human has been estimated at 0.03mg of dried toxin. <ref>http://www.springerlink.com/content/mq7x176638130747/</ref> | + | '''''Clostridium botulinum''''' is the name of a group of [[bacteria]] commonly found in soil.
