Fig. 4. Antioxidant enzyme activity induced by L. fermentum IDCC 3901-fermented products in UVB-irradiated HaCaT cells. SOD (A) and CAT (B) activities were measured using colorimetric assay kits. One unit of SOD is defined as the amount that inhibits the xanthine oxidase activity by 50% under the assay conditions, while one unit of CAT activity is defined as the amount that degrades 1 μmol of hydrogen peroxide per minute. ad Different letters indicate significant difference at p<0.05 level. The combination letter ‘cd’ is not significantly different from ‘c’ or ‘d’. SOD, superoxide dismutase; CAT, catalase; CL, cell lysate; CFS, cell-free supernatant.
