Immobilization of a Pleurotus ostreatus Laccase Mixture on Perlite and Its Application to Dye Decolourisation

Table 3

Immobilized enzyme samples employed in decolourisation experiments. Initial and final activity refer to laccase activity measured on solid carrier at the beginning and at the end of the decolourisation experiment.
