Patent ID: 6867023

Claim:
A production method of a polyhydroxyalkanoate comprising a monomer unit having the following chemical formula (2): wherein R represents an arbitrarily selected substituent and x represents an integer of 0 to 8, wherein the polyhydroxyalkanoate production method comprises a step of culturing a microorganism in a culture medium containing a substituted fatty acid ester having the following chemical formula (1): wherein R and R′ separately represent an arbitrarily selected substituent and x represents an integer of 0 to 8, wherein if R is H, x is not 1 or 2 in chemical formulas (1) and (2), the microorganism being capable of taking the substituted fatty acid ester into its cells and synthesizing the polyhydroxyalkanoate in the culture medium, wherein the polyhydroxyalkanoate production method further comprises a step of isolating the polyhydroxyalkanoate produced by the microorganism.
