New microorganism capable of producing polyhydroxyalkanoate, polyhydroxyalkanoate synthase, and gene encoding the same

摘要

PROBLEM TO BE SOLVED: To provide a new microorganism capable of producing a polyhydroxyalkanoate (PHA), a PHA synthase gene, an expression cassette including the gene, a vector including the expression cassette, a transformant transformed by the vector, a polypeptide having PHA synthase activity, a method for producing a PHA synthase and a method producing a PHA. SOLUTION: The new microorganism is capable of producing a polyhydroxyalkanoate comprising a 168 rRNA gene whose polynucleotide sequence shows 99% or more homology to a polynucleotide sequence represented by SEQ ID No: 1, having an optimum temperature of an activity temperature range for the growth and PHA production of the microorganism of at least 45°C and being capable of growing at a pH range from 6 to 10.
