Extracellular phenoloxidase and peroxidase enzyme production during interspecific fungal interactions

摘要: Extracellular phenoloxidase enzymes have been implicated in the offensive/defensive strategies employed by fungi during interactions. To determine whether these are involved Basidiomycete confrontations, a number of pairings between two brown-rot Basidiomycetes (Serpula lacrymans and Coniophora puteana) several Deuteromycetes (Trichoderma spp. Scytalidium FY) were performed. Laccase production was observed pure cultures C. puteana FY, interactions involving species. also detected S. all three Trichoderma isolates, although not respective cultures. Tyrosinase release most frequently T. harzianum SIWT 25, other species released tyrosinase under certain conditions, peroxidase interspecific One exception viride 110 as this fungus did produce experimental parameters utilized, inhibited self-pairings isolates. laccase much less on low nutrient medium, affected strongly.
