Table 1: Re-usability of DEAE-immobilized PGP in decolourization of dye and dye mixture. Immobilized PGP was independently incubated with DR19 and mixture of dyes (DR19+DB9) (150 mL) at 40°C. Dye decolourization was determined after incubation period of 2 h. The immobilized enzyme was collected by centrifugation (3000 × g) and stored in assay buffer at 4°C overnight. The similar experiment was repeated 10 times. Each value represents the mean for three independent experiments performed in duplicate.
