摘要： A process and resulting product is provided in which a vulcanized solid particulate, such as vulcanized crumb rubber, has select chemical bonds altered by biotreatment with thermophillic microorganisms selected from natural isolates from hot sulfur springs. Following the biotreatment, microwave radiation is used to further treat the surface and to treat the bulk interior of the crumb rubber. The resulting combined treatments render the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger loading levels and sizes of the treated crumb rubber can be used in new rubber mixtures and good properties obtained from the new recycled products.

摘要： 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.

摘要： An object of the present invention is to provide a method for efficiently degrading a biodegradable resin. In particular, the present invention relates to a method for degrading a biodegradable resin, the method comprising degrading the biodegradable resin in a buffer solution containing a biodegradable resin-degrading enzyme having an optimum pH of 7.5 or higher, wherein no anion derived from a buffer component is present on one side of an equilibrium equation of buffering of the buffer solution, and a pH of the buffer solution is adjusted within a pH range which gives conditions for shifting the equilibrium towards the side on which no anion is present. Further, the present invention relates to a method for degrading a biodegradable resin, the method comprising degrading the biodegradable resin in an enzymatic reaction liquid containing a biodegradable resin-degrading enzyme having an optimum concentration, wherein the degradation is conducted in a reaction liquid having an enzyme concentration which gives a biodegradable resin degradation ratio of 60% or higher, where a biodegradable resin degradation ratio at said optimum concentration is referred to as 100%.
