Abstract
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 wood-rotting fungus, Stereum sp. strain TN4F, was isolated from a fruit body, and its coexisting cultivable bacteria were isolated from its substrate; natural white-rot decayed wood. The effects of bacteria on fungal growth were examined by confrontational assay in vitro. A growth-promoting bacterium for this Stereum strain was identified as Curtobacterium sp. TN4W-19, using 16SrRNA sequencing. A confrontational assay revealed that 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.
