Biosystematika, fylogenetické vzťahy a distribúcia vreckatých húb z radu Leotiales v Karpatoch
Biosystematics, fylogeny and distribution of ascomycetes of the order Leotiales in the Carpathians
Program: VEGA
Zodpovedný riešiteľ: Mgr. Kučera Viktor, PhD.
Annotation: Most members of the order Leotiales are quite rare and are endangered almost in all countries of their occurrence. The order includes two families, Geoglossaceae (8 genera) and Leotiaceae (3 genera). They occur in some forest areas but predominantly they are associated with specific non-forest habitats, such as peat bogs, meadows, pastures and also sand dunes. Recently numerous new taxa are being described but no determination manual for their identification is available. Latest estimate includes about 25 taxa of the order in the Carpathians but delimitation of most of them is vague. We have identified serious taxonomical problems in genera Geoglossum, Microglossum and Thuemenidium that have to be solved. Taxonomical data will support consequent phylogenetic analyses and discussion on paraphyletic origin of genera. Field collections from the Carpathians, type and other material held in fungaria also published records will allow us to summarize ecology, construct distribution maps and propose threat status.

Mikrobiálna diverzita a sekundárne metabolity prítomné v tradičných slovenských syroch
The microbial diversity and secondary metabolites in traditional Slovak cheeses
Program: VEGA
Zodpovedný riešiteľ: Mgr. Mikušová Petra, PhD.
Annotation: Dairy products play an important role in nutrition and require permanent monitoring of microbial contamination. This is due to toxic metabolites produced mainly by microscopic fungi pose a health risk to the consumer. Actual, routine monitoring of cheeses is focused only on regulated AFM1. The aim of this project is to expand and deepen knowledge about the diversity of microcenosis, as well as the detection of their metabolites present in cheeses. Should we not find out the current situation in Slovakia, also on the basis of scientific works, which informs about new metabolites as well as new species of microscopic fungi in dairy products such as cheese? From this point of view, scientific questions concerning the presence of undesirable secondary metabolites in cheeses, their quantity as well as the precise identification of their potential producers are highly important.
