| Abstract: | The antioxidative mechanisms of lactic acid bacteria were introduced in this paper. The lactic acid bacteria and cell-free extracts were studied in vitro about their abilities of hydroxyl radical scavenging, hydrogen peroxide scavenging, 1,1-diphenyl-2-picrylhydrazl scavenging, lipid peroxide inhibiting, metal iron chelating and their activities of total reducing and superoxide dismutase. The results of the antioxidative activities of lactic acid bacteria in vivo were also discussed. |
