Abstract:
The ability of the fungus Rhizoctonia praticola to produce an induced extracellular laccase was examined. Potential inducers, including substituted phenols, anilines, and benzoic acids, were added at a concentration of 1 mM to the growth media of fungal cultures. Of the 11 compounds tested, 5 were found to have an inductive effect. The most effective inducer, p-anisidine (p-methoxyaniline), stimulated laccase production by a factor of 30. Other parameters which influenced the production of laccase were temperature, condition of the mycelia at the time of the induction, and the concentration of the inducer. A comparison of the p-anisidine induced laccase with the constitutive laccase showed noticeable similarities in K m , pH optimum, and mobility in gel electrophoresis, suggesting that the two enzymes may be similar.
