  • Phanerochaete chrysospoirium strains CNCM I-1511, I-1512 and I-1513 for producing lignin peroxidase and manganese peroxidase
    Patent number: 5972672
    Abstract: Phanerochaete chrysosporium strains CNCM numbers I-1511, I-1512 and I-1513 are found that produce increased amounts of manganese peroxidase (MnP) and lignin peroxidase (LiP). Immobilized cells may be used for culturing, and culture media is preferably supplemented with a phospholipid as a carbon source and/or veratryl alcohol to stabilize enzymes produced. Culturing conditions can be selected to modify the MnP/LiP ratio in favor of the production of MnP or LiP.
