ABSTRACT:
PHA containing a novel 3-hydroxy-thioalkanoic acid unit having a highly reactive thienyl group in a side chain thereof, and a method of producing the same are provided. Specifically, 5-(2-thienylsulfanyl) valeric acid represented by Chemical Formula [4] below and 6-(2-thienylsulfanyl) hexanoic acid represented by Chemical Formula [5] below are provided. Further, a method of producing PHA, comprising the step of collecting PHA from cells of a microorganism cultured in a medium containing the valeric acid or hexanoic acid, and a novel PHA represented by Chemical Formula [1] below are provided.(n denotes an integer of 1 to 9)
