Interference of a commercial catalase preparation in laccase and peroxidase activities

The influence of commercial catalase preparations (fungal and bovine origin) on laccase and peroxidase activity assays was evaluated using enzymatic extracts obtained from several basidiomycetes grown under different culture conditions. No hydrogen peroxide was detected in the extracts. Inhibition o...
