Extracellular ligninolytic enzyme production by Phanerochaete chrysosporium in a new solid-state bioreactor

摘要

The production of manganese-dependent peroxidase (MnP) and lignin peroxidase (LiP) by the fungus Phane-rochaete chrysosporium (ATCC 24725) in a new bioreactor, the Immersion Bioreactor, which grows cells under solid-state conditions, was studied. Maximum MnP and LiP activities were 987 U l~(-1) and 356 U l~(-1), respectively. The polymeric dye, Poly R-478, was degraded at 2.4 mg l~(-1) min~(-1) using the extracellular culture filtrate.
