Outline of Final Research Achievements

White-rot basidiomycetes are the main decomposers of woody biomass in forest ecosystems. Little is known, however, about the interactions between white-rot fungi and other microorganisms in decayed wood. A comprehensive confrontational analysis of natural wood-decaying fungi and coexisting bacteria revealed that some bacteria can promote the growth of fungi. For example, Curtobacterium sp. TN4W-19 significantly promoted the mycelial growth of Stereum sp. TN4F in the direction of the bacterial colony, without direct contact between the mycelium and bacterial cells. This is the first report of a positive interaction between a white-rot fungus and a coexisting bacterial strain in vitro.
