Abstract:
This study was based on live yeast cell derivative (LYCD), which was produced by live yeast cell stressed with high temperature and H 2O 2. The results showed that pretreating of low dose(37℃and 0.2mmol/L H 2O 2) could increase the content of GSH and the activity of SOD and CAT. These pretreatment could induce the resistance to lethal concentration of H 2O 2. LYCD was produced by yeast treated with 37℃ and 0.2mmol/L H 2O 2. And it was found that the survival of yeast treated with lethal concentration of H 2O 2 obviously increased, while LYCD was added in yeast culture. It indicated that LYCD could have resistance to oxidative condition.
