Versicolor suited to grow and produce laccases at pH value 3.5-5.7, and unbuffered media were able to get good laccase productivity though buffered media could get higher laccase activity. Metal ions Cu(superscript 2+) and Mn(superscript 2+) in the culture could remarkably increase the activity of laccases. The optimal concentration of Cu(superscript 2+) was 0.008-0.08mmol/L, and the optimal concentration of Mn(superscript 2+) was about 0.01mmol/L, when the culture contained 0.1mmol/L 2,5-dimethoxyaniline.
