PRODUCTION METHOD FOR COPOLYMER POLYHYDROXYALKANOATE USING GENETICALLY MODIFIED STRAIN OF FATTY ACID &Bgr;-OXIDATION PATHWAY

摘要

The purpose of the present invention is to provide a method for producing poly(3-hydroxybutanoic acid-co-3-hydroxyhexanoic acid) [P(3HB-co-3HHx)] having a high 3-hydroxyhexanoic acid fraction, using a plant oil as a basic raw material. The present invention provides a method for producing P(3HB-co-3HHx) having a high 3-HHx acid fraction, using a plant oil as a basic raw material, by destroying at least one gene coding 3-hydroxyacyl-CoA dehydrogenase or at least one gene coding 2-enoyl-CoA hydratase in a chromosome of a modified Cupriavidus necator strain imparted with [P(3HB-co-3HHx)] production capability, and thus suppressing the expression of said gene.
