Abstract
AbstractAcceleration of the biodegradation of poly(L‐lactide) (PLA) was studied. We found that the degradation rate of high molecular weight (1.3×105) PLA film was greatly increased by the addition of gelatin into the culture medium of the microorganisms. 100 mg of PLA film was almost completely degraded by the fungus, Tritirachium album (eukaryotic microorganisms), and by an actinomycete, Saccharothrix waywayandensis (prokaryotic microorganisms). In addition to gelatin, various insoluble proteins, peptides and amino acids also accelerate the biodegradation of PLA. Silk fibroin was the best inducer for the production of PLA‐degrading enzymes of an actinomycete, Amycolatopsis orientalis.
