Role hub v biogeochemických cyklech kovů a implikace pro fytoremediace The role of fungi in biochemical cycles of the metals and the implication to phytoremediation
Fungi and their physiological traits are intimately involved in biogeochemical transformations of inorganic compounds and
minerals, providing an essential role and being important as irreprecable environmental component at local and global scales.
The study of the role that fungi play in geochemical cycles is termed geomycology. Besides their role in cycling of the elements
as carbon, nitrogen, sulphur or phosphorus, fungi significantly contribute to cycling of many other elements, including toxic
heavy metal species. Here we describe fundamental mechanisms employed by fungi in weathering and solubilization of rocks and
minerals or, as opposite, in mycogenic mineral formation, which all together have an impact on mobility of metals in the environment.
The importance and potential of mycorrhiza in phytoremediations is also discussed.
Key words: geomycology, mycorrhizas, mycotransformation, metal mobilization, metal immobilization.
