  • Patent number: 11702681
    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.

  • Publication number: 20150061599
    Abstract: A portable electronic apparatus includes a terminal, a grip portion and a controller. A first battery is provided inside the terminal. The grip portion is positioned outside of the terminal and includes a second battery unit electrically connected to the terminal. The controller controls the second battery unit to supply power to the terminal before power of the first battery unit is supplied to the terminal. Accordingly, the controller first supplies the power of the second battery unit to the terminal rather than the power of the first battery unit.
