| Abstract |
|
Beneficial physiological effects of biopolymer have been well documented. In the process of Cheongkukjang fermentation, various biopolymers were produced by Bacillus strains. In this study, we examined the effects of biopolymer produced by mixed Bacillus strains composed equal amounts of B. circulans, Brevibacillus brevis, B. licheniformis, B. subtilis,B. coagulans and B. sterothermophilus separated from traditional Cheongkukjang on antioxidative activities including electron donating ability (EDA), reducing power and superoxide dismutase (SOD) like activity, and skin coloring and aging. Whereas EDA was 59.40% in the presence of 4% biopolymer, reducing power was the highest at 10% biopolymer. Also, SOD-like activity was 44.91% at 4% biopolymer. On the other hand, inhibitory activity of tyrosinase in all samples were lower than that of 0.5% L-ascorbic acid. Additionally, inhibitory activity of elastase by biopolymer was the highest value of 85.71% at 1% biopolymer concentration. These results suggest that biopolymer may prevent (regulate) skin aging and coloring via antioxidative effect, and inhibitory activity of tyrosinase and elastase. |
