Title:
How to produce a plastic raw material and a related substance in Blue-green algae
Document Type and Number:
Japanese Patent JP5946080
Kind Code:
B2
Abstract:
The purpose of the present invention is to use cyanobacteria, which are photosynthetic organisms, use solar energy and carbon dioxide, build a system for efficiently producing polyhydroxy alkanoic acid (PHA), which is a bioplastic that accumulates inside cyanobacteria cells, and increase the production quantity of PHA. The present invention pertains to cyanobacteria which overexpress the rre37 gene, and a method for producing polyhydroxy alkanoic acid by cultivating said cyanobacteria.
