Effect of surfactant on the catalyzed oxidation of 2,6-dimethylphenol by rhus vernicifera laccase

Rhus vernicifera laccase-catalyzed oxidation of 2,6-dimethylphenol (DMP) was studied in the presence of 12 surfactant (Sf). C16H33N+ (CH3)3 Br− (CTAB) etc 5 cationic Sf and C12H23SO4Na (SDS) etc 3 anionic Sf can promote the reaction in the different extent. The promotion of CTAB is the largest among them. The affected factors of the reaction—concentration of CTAB and DMP, pH, temperature, laccase quantity and reaction kinetics are inverstigated further. The nonionic Sf-Tween-20, Tween-60, Tween-80 and Triton X-100 have not promotion to the reaction.
