Dead fungal mycelium in forest soil represents a decomposition hotspot and a habitat for a specific microbial community

Popis výsledku v původním jazyce

Turnover of fungal biomass in forest litter and soil represents an important process in the environment. To date, knowledge of mycelial decomposition has been derived primarily from short-term studies, and the guild of mycelium decomposers has been poorly defined. nHere, we followed the fate of the fruiting bodies of an ectomycorrhizal fungus in litter and soil of a temperate forest over 21 wk. The community of associated microbes and enzymatic processes in this specific substrate were described. nThe decomposition of fungal fruiting bodies exhibited biphasic kinetics. The rapid initial phase, which included the disappearance of DNA, was followed by a slower turnover of the recalcitrant fraction. Compared with the surrounding litter and soil, the mycelium represented a hotspot of activity of several biopolymer-degrading enzymes and high bacterial biomass. Specific communities of bacteria and fungi were associated with decomposing mycelium. These communities differed between the initial and late phases of decomposition. The bacterial community associated with decomposing mycelia typically contained the genera Pedobacter, Pseudomonas, Variovorax, Chitinophaga, Ewingella and Stenotrophomonas, whereas the fungi were mostly nonbasidiomycetous r-strategists of the genera Aspergillus, Penicillium, Mortierella, Cladosporium and several others. nDecomposing ectomycorrhizal fungal mycelium exhibits high rates of decomposition and represents a specific habitat supporting a specific microbial community.
