  • Title: Characterization of extracellular peroxidases produced by acetate-buffered cultures of the lignin-degrading basidiomycete Phanerochaete chrysosporium.
    Author: Dass SB, Reddy CA.
    Journal: FEMS Microbiol Lett; 1990 Jun 01; 57(3):221-4. PubMed ID: 2210334.
    Abstract:
    Growth of Phanerochaete chrysosporium in a nitrogen-limited medium buffered with sodium acetate, instead of the commonly used 2,2-dimethylsuccinate (DMS), resulted in quantitative and qualitative differences in the production of various extracellular lignin peroxidases (LIPs) and manganese-dependent peroxidases (MNPs) involved in lignin degradation. The results indicate that production of LIPs and MNPs can be selectively enhanced by manipulation of culture conditions. Partial N-terminal analyses of the major LIPs and MNPs have made it possible to assign a specific protein to the specific genes and cDNAs that have been reported recently. The LIPs and MNPs differed widely in their ability to decolorize various dyes that are known to be degraded by the lignin degrading enzyme system of P. chrysosporium.
