Combined effect of copper and initial pH of the culture medium on production of laccase and manganese peroxidase by Stereum hirsutum (Willd) Pers.

Stereum hirsutum is a white-rot fungus which produces laccase and manganese peroxidase as part of its ligninolytic system. Maximal ligninases production (under the conditions studied) was obtained in the media containing 250 μM Cu++ along with a pH value of 5.5. The fitting of ligninase production t...

Sumario:Stereum hirsutum is a white-rot fungus which produces laccase and manganese peroxidase as part of its ligninolytic system. Maximal ligninases production (under the conditions studied) was obtained in the media containing 250 μM Cu++ along with a pH value of 5.5. The fitting of ligninase production to a linear equation showed negative interaction between increas ng values of pH and concentration of copper.
