High molecular weight poly-gamma-glutamic acid (> 2000 kDa) |
| 摘要 |
<p>The present invention relates to poly-gamma-glutamic acid (or poly-gamma-glutamate, ³-PGA) an edible, soluble, anionic, and biodegradable high molecular-weight polymer. Bacillus subtilis var. chungkookjang produces an ³-PGA with a higher molecular-weight than other extracellular ³-PGAs derived from general Bacillus sp. strains. Accordingly, the ³-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.</p> |
