Tyrosinase shows distinct catalytic activity in different reaction media. However, both the stability and activity of tyrosinase declined slowly with the increase in the content of methanol in methanol/chorform mixture solvent. The ratio of methanol and chloroform has a significant effect on the products of enzyme- initiated oxidation-Michael addition reaction in the presence of aniline.
