Autofluorescence dřevokazné houby Fomes fomentarius
Žižka, Zdeněk ; Gabriel, Jiří
We observed the core of wood-rotting fungus Fomes fomentarius fruiting bodies in fluorescent microscopes. When excited with blue light, they featured thin-walled generative hyphae with septa and clamps, some of which emitted a strong yellow, yellow-green to yellow-red autofluorescence. In addition, we found yellow-red fluorescing thick-walled skeletal hyphae and strongly fluorescent thick-walled pith sets. On using green excitation, intensive red fluorescence was observed not in all these fruiting body components but also in the rest of the wood material
Fomes fomentarius fruit body - a model for decompositionof cellulose in vivo
Gabriel, Jiří ; Baldrian, Petr ; Merhautová, Věra ; Kofroňová, Olga ; Král, J. ; Proška, J.
Activities of both cellulolytic and ligninolytic enzymes and heavy metal content in fruit body of Fomes fomentarius were studied. The activities of ligninolytic enzymes were higher in the core.
Fructification of wood-rotting fungi on milled straw andranslocation of metals from substrate to fruit bodies
Gabriel, Jiří ; Merhautová, Věra ; Baldrian, Petr
The effect of metals on formation of fruit bodies of several fungi was studied. Earlier formation of fruit bodies of Pleurotus ostreatus was found in the case of Mn, Cd, Cu, Fe and Zn.
Decomposition of cellulose and hemicelluloses by wood-rotting fungi and effect of heavy metals
Valášková, V. ; Merhautová, Věra ; Gabriel, Jiří ; Baldrian, Petr
Degradation of cellulose and hemicelluloses by brown-rot fungi is significantly affected by heavy metals. The activity of cellulases is increased in the presence of zinc.
Accumulation of metals in fruiting bodies of Fomes fomentarius
Gabriel, Jiří ; Baldrian, Petr ; Kofroňová, Olga ; Benada, Oldřich
Fruit body of Fomes fomentarius was used for detailed study of metal distribution within fungus and wood. Higher content of Mn was found in the core.
Accumulationn of heavy metals by wood-rotting fungi
Gabriel, Jiří
This work summarizes data on heavy metal content in wood-rotting fungi. Their effect on the physiology of fungi is also discussed.
