Bioactivity and inhibiton effects of greengage ferment

In this paper the antioxidant activity and enzyme activity and bacteriostasis of greengage ferment were studied. The results showed that the antioxidant activity and enzyme activity of greengage ferment were strong.Total oxidation resistance was equal to oxidation resistance of 100 μg/mL VitC when greengage ferment volume concentration was 0.25%. When greengage ferment's volume concentration was 45%,OH· clearance rate reached 83.2% and DPPH· clearance rate reached 96.5% when the volume concentration was 8%. The reducing power of greengage ferment was equal to reducing power of 100 μg/mL VitC when greengage ferment volume concentration was 15%. When greengage ferment's volume concentration was 30%,greengage enzyme superoxide dismutase(SOD)had the highest activity,which was 75.64 U/mL. When greengage ferment's volume concentration was 15%,protease activity was 15.84 U/mL and lipase activity was lower,which was 1.67 U/mL. Inhibition effect on Staphylococcus aureus,Escherichia coli,Bacillus subtilis inhibitory was strong.The inhibition zone of Staphylococcus aureus,Escherichia coli,Bacillus subtilis respectively were(19.9±0.56),(17.2±0.15),(19.0±0.3) mm.
