ABSTRACT:
A polyhydroxyalkanoate is disclosed which has in the molecule a unit represented by Chemical Formula (1).wherein R is arbitrarily selected from a hydrogen atom, a halogen atom, CN, NO2, COOR′, SO2R″, CH3, C2H5, C3H7, C(CH3)2H and C(CH3)3; where R′ is H, Na, K, CH3or C2H5, and R″ is OH, ONa, OK, a halogen atom, OCH3or OC2H5; and x is an integer arbitrarily selected from 1 to 8; with the proviso that a polyhydroxyalkanoate is excluded which has a hydrogen atom as R and x in all the units is 2 or 4. Also disclosed is a process for producing the polyhydroxyalkanoate by the use of a microorganism having the ability to produce the polyhydroxyalkanoate and accumulate it in the bacterial body.
