โฆ Synopsis
Lignin peroxidase (LIP) and manganese peroxidase (MnP) activity in Coriolus versicolor 290 reach maximal levels after 8 and 10 days growth respectively.
Increases in LiP activity were observed upon supplementation of the medium with veratryl alcohol. The physiology of this strain is quite distinct from that of the better studied Phanerochaefe chrysosporiurn in that extracellular LiP activity is enhanced at carbon levels of 1 Og/Ll . This increase in LIP enzyme activity at higher carbon levels appears to be mediated at the transcriptional level, given that lip and mnpmRNA levels mirror the observed enzyme activity levels quite closely.

The depolymerization of humic acids (HAs) obtained from low-rank coal (lignite) to fulvic acids (FAs) was investigated in a cell-free system (in vitro) using manganese peroxidase (MnP) from the white-rot fungus Clitocybula dusenii b11. MnP was produced in surface cultures of C. dusenii which were in
