Table 3: Dye decolourization in batch processes. DR 19 or mixture of dyes (DR19+DB9) (200 mL) was independently treated with soluble and immobilized PGP (180 U) for varying times and temperatures in batch processes. Aliquots were taken from containers at different time intervals for measuring the dye colour removal. Each value represents the mean for three independent experiments.
