摘要
The white-rot fungus Trametes versicolor grown in submerged culture produced two laccase isoenzymes, LacI and LacII. Addition of insoluble lignocellulosic materials into the culture medium increased the total laccase activity. The proportion of laccase isoenzymes also changed depending on the lignocellulosic material employed, with ratios of activity LacII/LacI from 0.9 (barley straw) to 4.4 (grape stalks). Besides, this proportion played an important role in the dye decolourisation.
