[The effect of copper ions on the production of laccase by the fungus Lentinus (Panus) tigrinus].
The basidiomycete Lentinus tigrinus was cultured in media containing copper ions added at different growth stages. Copper ions at increased concentrations decelerated of the fungal biomass accumulation. The later Cu2+ ions were added, the better the fungal mycelium developed, and the toxic effect of Cu2+ was less pronounced. The maximum laccase activity (47 U/ml) was observed in the presence of 1.5-2.0 mM Cu2+ added on day 4 of cultivation.
