General Information

General Information Comment Organism
metabolism versatile peroxidase of the white-rot fungus Lentinus tigrinus is involved in biotransformation of soil humic matter. Alkali-extractable and acid-insoluble constituents of SOM (HA) contain true macromolecular components, stable in the presence of 0.1% sodium dodecyl sulfate but degradable/resynthesizable by oxidative enzymes acting on covalent linkages. The humic acid degradation in the presence of laccase occurs at slower initial rate than in the presence of the enzyme. Each of the enzymes causes about 60% color loss and almost complete degradation of HA into smaller molecules within 2 weeks of cultivation. Depolymerization of HA in the culture liquid in the presence of laccase is accompanied by polymerization of degradation products on mycelium. Humus macromolecules are not stable to oxidative enzymes once desorbed from the mineral phase. Laccase of Lentinus tigrinus is comparable by its degradation potential to VP, and interfacial secondary synthesis reactions occur during humus decay in the presence of laccase.
