The effects of various synthetic medium components and their interactions with each other ultimately impact laccase production in fungi. This was studied using a laccasehyper-producing marine-derived basidiomycete, Cerrena unicolor MTCC 5159. Inducible laccases were produced in the idiophase only after addition of an inducer such as CuSO4. Concentration of carbon and nitrogen acted antagonistically with respect to laccase production. A combination of low nitrogen and high carbon concentration favored both biomass and laccase production. The most favorable combination resulted in 917 U L-1 of laccase. After sufficient growth had occurred, addition of a surfactant such as Tween 80 positively impacted biomass and increased the laccase activity to around 1,300 U L-1. Increasing the surface to volume ratio of the culture vessel further increased its activity to almost 2,000 U L-1.
