ABSTRACT:
The present invention provides novel microorganisms that directly biodegrade polylactide resins and plastics containing the same as well as a method therefor. Specifically, the present invention provides a method for degrading polylactide resins, wherein the polylactide resins are degraded by an actinomycete belonging to the genusSaccharothrix, Streptoalloteichus, Kibdelosporangium, Lentzea, Actinokineospora, Saccharomonospora, Saccharopolyspora, orActinopolyspora.
