A lignin degrading enzyme, manganese peroxidase has detected in culture supernatants of Phanerochaete chrysosporium NCIM 1197 grown under various nitrogen sources. The present work was carried out to determine the effect of variable concentration of ammonium tartrate, ammonium chloride and urea on MnP production. Highest level of manganese peroxidase activity, (118.60 ± 2.26 U/ml) was observed in the production medium supplemented with urea (0.0108 mM) and glucose (55.55 mM). A very high C:N ratio in the medium favours the MnP production. The production of the MnP enzyme is a major demand in environmental biotechnology, so outcome of this study can help in scale-up of the enzyme.
