title: A simple and rapid method to gain high amounts of manganese peroxidase with immobilized mycelium of the agaric white-rot fungus Clitocybula dusenii.
abstract: The agaric basidiomycete Clitocybula dusenii was used for the production of the extracellular ligninolytic enzyme, manganese (Mn) peroxidase. An immobilization technique is described using cellulose and polypropylene as carrier for the fungal mycelium. High amounts of Mn peroxidase were obtained with agitated cultures of immobilized fungus (up to 3,000 U l(-1)) while the biomass was recovered and used for further production cycles. Purification of Mn peroxidase revealed the existence of two forms: MnP1 (molecular mass 43 kDa, pI 4.5) and MnP2 (42 kDa, pI 3.8).
