Clostridium botulinum is a kind of bacteria growing in anoxic environment, which has strong viability in canned food and sealed pickled food and is one of the most toxic bacteria.

Clostridium botulinum belongs to anaerobic bacteria and is strictly anaerobic. It can not only decompose glucose, maltose and fructose in gastrointestinal tract to produce acid and gas, but also digest and decompose meat residue, making it black, rotten and smelly. In anaerobic environment, this strain can secrete strong botulinum toxin, which can cause special symptoms of neurotoxicity, and the disability rate and mortality rate are extremely high.

Clostridium botulinum is a deadly pathogen, which secretes botulinum toxin during reproduction. This toxin is the most toxic substance known at present, which can inhibit the release of acetylcholine from cholinergic nerve endings, leading to muscle relaxation and paralysis. Scientists and beauticians have taken a fancy to the effect that botulinum toxin can temporarily paralyze muscles. Doctors have found that it plays an extraordinary role in eliminating wrinkles, and its effect far exceeds that of any other cosmetic or plastic surgery. As a result, cosmetic surgery using botulinum toxin to eliminate wrinkles came into being.
