Document Type and Number:
WIPO Patent Application WO/2024/075597
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a copolymer polyhydroxyalkanoic acid mixture by culturing a microorganism. The mixture contains: a fraction (I) which includes a copolymer polyhydroxyalkanoic acid having a 3-hydroxybutyric acid structural unit and a 3-hydroxyhexanoic acid structural unit and in which the average composition ratio of 3-hydroxyhexanoic acid is 9 mol% or greater and less than 20 mol%; and a fraction (II) which includes a polyhydroxyalkanoic acid having a 3-hydroxybutyric acid structural unit and in which the average composition ratio of 3-hydroxyhexanoic acid is 0-8 mol% inclusive. In the copolymer polyhydroxyalkanoic acid mixture, the weight ratio of the fraction (II) is 45% or greater.
