Activies of Enzymes During the Litter of Pinus sylvestris var. mongolica Degradation by Three Strains of Mycelial Fungi
三株丝状真菌分解樟子松凋落物酶活性

Three strains of mycelial fungi, Alternaria sp., Penicillium sp. and Pestalotiopsis sp., high- frequently isolated from litter of Pinus sylvestris var. mongolica were as the research strain,, the current deciduous needles were as the active zymolyte, the method of fermentation was used to assay the mass defect of zymolyte and the activies of enzymes including laccase, manganese peroxidase (MnP), carboxymethyl cellulase (CMCase) and filter paper activity (FPA) in fermenting process, and try to comfirm the relationship between the activities of enzymes and the mass defect of zymolyte. The results show that the mass defect of zymolyte caused by Alternaria sp. is the highest. Alternaria sp. can produce highest activity of Laccase, CMCase and FPA. Penicillium sp. can produce highest activity of MnP. The three strains of mycelial fungi are all belong to lignocellulose-decomposing fungi of the group of functional fungi.
