Title:
METHOD FOR PRODUCING POLYHYDROXYALKANOIC ACID USING PURPLE PHOTOSYNTHETIC BACTERIUM
Document Type and Number:
WIPO Patent Application WO/2016/208542
Kind Code:
A1
Abstract:
The present invention addresses the problem of developing and providing a method for producing a polyhydroxyalkanoic acid (PHA) at reduced cost, with high efficiency and in a large quantity using a microorganism.
Provided is a method for producing a PHA, comprising culturing a purple photosynthetic bacterium while stirring a liquid culture medium and while irradiating the liquid culture medium with far infrared light to produce cells of the bacterium in each of which the PHA is accumulated.
