Description: Based on its dye decolorization activities four Trichoderma strains were screened as laccase producers. The strains were identified as T. atroviride, T. longibrachiatum, T. reesei, and T. viride. It was determined that it was expedient to screen laccase producing Trichoderma strains among cellulase producing strains on the basis of its dye decolorization activity (correlation coefficient between was 0.87). For further studies T. atroviride, T. longibrachiatum and T. viride were screened as prospective laccase producers
