Optimisation Of Lignin Peroxidase Production From Pycnoporus Sp.

Ligninase or lignin peroxidase is gaining importance for their biotechnology application due to its integral role in the biodegradation of lignin, lignin related aromatic compounds and the potential use in industrial processes such as biopulping, biobleaching and bioremediation. Lignin peroxidase h...
