POLY-β-HYDROXY ALKANOATE (PHA) COPOLYMER, METHOD OF ITS PRODUCTION, THE MICROBE WHICH PRODUCES IT, AND PHA COPOLYMER BLEND

摘要

In the present invention a new poly-β-hydroxy alkanoate (PHA) copolymer is produced in the cell of Pseudomonas cepacia KYG/505 (KCCM 10004) by the method of its production, and a variety of polymer blends of PHB and PHA are developed. The PHA copolymer of the present invention can improve the properties of known PHB through blending and, having double bonds on some of its side chains, enjoys capabilities for organic synthesis, whereby it can be made use of in production of polymers with various properties and biodegradability.
