| 摘要 |
An object of the present invention is to provide a microorganism strain capable of accumulating P(3HB-co-3HH) having an ultra high molecular weight at a high level, and to provide a method of producing a safe and inexpensive copolymerized polyester using the same. The present invention is related to a microorganism which is obtained by introducing a polyhydroxyalkanoic acid synthase gene and a 3-ketoacyl-ACP reductase gene into at least one host microorganism selected from the group consisting of those belonging to genus Ralstonia, genus Aeromonas, genus Alcaligenes and genus Pseudomonas to allow for transformation. |
