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 genus Saccharothrix, Streptoalloteichus, Kibdelosporangium, Lentzea, Actinokineospora, Saccharomonospora, Saccharopolyspora, or Actinopolyspora.

-18. (Cancelled)
A method for degrading polylactide resins, wherein the polylactide resins are degraded by an actinomycete:
- (a) belonging to the genus Saccharothrix;
- and (b) that is at least one bacterium selected from the group consisting of Saccharothrix flava, Saccharothrix coeruleofusca, Saccharothrix longispora, Saccharothrix australiensis, Saccharothrix mutabilis subsp. mutabilis, Saccharothrix aerocolonigenes subsp. aerocolonigenes, Saccharothrix syringae, Saccharothrix coeruleoviolacea, Saccharothrix cryophilis, Saccharothrix espanaensis, Saccharothrix texasensis, and Saccharothrix waywayandensis.
The method of claim 1, wherein the polylactide resins comprise poly-L-lactic acid or a copolymer of poly-L/D-lactic acid.
