Studies of the production and characterization of laccase activity in the basidiomycete Coriolopsis gallica, an efficient decolorizer of alkaline effluents
The basidiomycete Coriolopsis gallica decolorizes alkaline paper effluents efficiently. In this work, we found that C. gallica produces laccase during this decolorization process. This enzymatic activity was produced in all media studied; however, the highest enzymatic activity was obtained in a medium containing paper effluent, where laccase was detected on the 2nd day of the experiment. The laccase activity of C. gallica was purified and characterized. The amino-terminal sequence of this protein showed the highest similarity with the laccase I of the basidiomycete PM1 and with Coriolus hirsutus laccase.
