Earthworms

Decay of LDPE plastic by bacteria extracted from earthworm's guts

A publication lead by SLM researchers in collaboration with scientists from Mexico provides a potential for soil restoration.

They discovered a group of bacteria that live in the intestines of some earthworms and that have the capacity to degrade low density plastic. Although other bacteria and fungi that degrade plastics have already been reported, the newly reported could reduce the period of degradation of plastics to four weeks, while the other known come to take between three and nine months to get similar results.
