摘要: In order to understand the behavior of ligninolytic enzyme production by white rot fungi
Phanerochaetechrysosporium, study on time courses and a mathematical model for the
production of lignin peroxidase (LiP) andmanganese peroxidase (MnP) of the fungi was
undertaken. Based on the Monod-Jacob operon model, the ligninolyticenzyme would be
synthesized in the absence of a related repressor. The repressor is assumed to be active in
thepresence of ammonia nitrogen, and as combined as co-repressor, it causes the inhibition
of enzyme synthesis. Themodel can explain the mechanism of extracellular ligninolytic
enzyme production by white rot fungi. The results,as predicted by the model, correspond
closely to those observed in experimental studies. In addition, some lightis also shed on
unmeasured variables, such as the concentrations of repressor and mRNA that are related to
theenzyme synthesis.
