Degradable polyesters, a mixed culture of microorganisms for degrading these polyesters, and methods for making these substances |
| abstract |
Degradable polyesters useful in packaging, packing, agricultural, biomedical, and other applications are made by reacting amine-protected glutamic acid with diols or epoxy compounds. The polyesters include a thermoplastic main chain aliphatic polyester, a thermoset heterochain polyester and a thermoset heterochain aromatic polyester. Each of these polyesters can be hydrolyzed into monomers using a biological catalyst such as the enzyme lipase. The thermoplastic main chain aliphatic polyester and the thermoset heterochain polyester can be degraded to respiratory gases and biomass with a mixed culture of Rhizopus chinesis, Rhizopus delemar, Penecillium pinophilum, Aspergillus niger and Pseudomonas aeruginosa microorganisms. This mixed culture of microorganisms can also be used to degrade other polyesters containing hydrolyzable backbone polyesters. |
