  • var. producing high molecular weight poly-gamma-glutamic acid
    Patent number: 7582466
    Abstract: Bacillus subtilis var. chungkookjang, accession no. KCTC 0697BP, a salt-resistant B. subtilis variant isolated from “chungkookjang,” a traditional Korean fermented soy bean paste. This B. subtilis variant produces poly-gamma-glutamic acid (or poly-gamma-glutamate, ?-PGA), an edible, soluble, anionic, and biodegradable high molecular-weight polymer. Bacillus subtilis var. chungkookjang produces ?-PGA with a higher molecular weight than other extracellular ?-PGAs derived from general Bacillus sp. strains. Accordingly, the ?-PGA produced by Bacillus subtilis var. chungkookjang can be utilized for the development of high value-added products, such as cosmetics, absorption agents, and biodegradable plastic materials.
    Type: Grant
    Filed: December 31, 2005
    Date of Patent: September 1, 2009
    Assignee: Bioleaders Corporation
    Inventors: MoonHee Sung, DaeHeoun Baek, SeungGoo Lee, JaeJun Song, SeungPyo Hong, YoonHo Choi, SunYoung Shin, JaeSuk Han, Makoto Ashiuchi, Kenji Soda
  • var. producing high molecular weight poly-gamma-glutamic acid
    Patent number: 7091010
    Abstract: Salt-resistant Bacillus subtilis var. chungkookjang, accession no. KCTC 0697BP, separated from “chungkookjang” a traditional Korean fermented soy bean paste and its poly-gamma-glutamic acid (or poly-gamma-glutamate, g-PGA), an edible, soluble, anionic, and biodegradable high molecular-weight polymer. Bacillus subtilis var. chungkookjang produces g-PGA with a higher molecular weight than other extracellular g-PGAs derived from general Bacillus sp. strains and can be utilized for the development of high value-added products, such as cosmetics, absorption agents, and biodegradable plastic materials.
