چکیده انگلیسی
The white-rot fungus Trametes versicolor growing in submerged culture on a basal medium, with barley bran as a carbon source, produced two laccase isoenzymes LacI and LacII. The addition of metal ions to the culture medium was performed to improve the total laccase activity and to determine the effect on the production of laccase isoenzymes. From all the tested metals, only Cu2+ increased laccase activity (up to 12-fold with respect to control cultures) and T. versicolor in presence of all metals produced the two isoenzymes in different proportion with ratios of activity (LacI/LacII) varying between 0.11 and 0.51. This factor played an important role in the decolourisation of the textile dye Indigo Carmine.
