Inhibitory studies on PO and PPO activities. Comparison of the effects of general enzyme inactivators and selected PO or PPO inhibitors on A. chroococcum SBUG 1484 crude PO, P. cinnabarinus SBUG-M 1044 crude PO and A. bisporus PPO (tyrosinase) in 2 mM concentrations. Effects on bacterial and fungal PO activities were evaluated using 5 mM 2,6-DMP, whereas PPO activity in the presence of potential inhibitors was monitored in the oxidation of catechol (5 mM). Error bars refer to standard deviation by means of four replicates.
