Abstract
Disclosed is a mutant strain having the ability to produce polyhydroxybutyrate. The novel strain has a significantly high growth rate and an improved ability to produce PHB compared to existing PHB-producing cyanobacterial strains. Therefore, the novel strain is suitable for use in the production of PHB and the development of various products using PHB. In addition, the novel strain is useful as a photosynthetic strain for developing a PHB production process using industrial flue gas due to its ability to produce PHB from only CO2 without any additional organic carbon source. Also disclosed is a method for producing polyhydroxybutyrate using the mutant strain.
