1.11.1.13 manganese peroxidase culture condition:polyurethane foam-grown cell higher concentrations of foam and lower levels of spore inoculums result in the formation of scattered mycelial pellets, increased autolysis of chlamydospore-like cells (a reservoir of MnP), and a higher activity of MnP. Even though MnP is a secondary metabolite, the addition of 5times more glucose and diammonium tartrate, as carbon and nitrogen sources, results in a 4fold increase in the dry cell mass. MnP activity decreases under these conditions to less than half, due to the formation of increasingly dense pellets and the inhibited lysis of chlamydospore-like cells 685720
