and Associated with Maize Seeds and Their Potential to Form Selected Secondary Metabolites.

The occurrence and diversity of and in maize seeds and their role in this cereal are poorly understood. Therefore, the present study aimed to investigate and communities found in endosphere of maize seeds collected from fields in Poland and their potential to form selected bioactive substances. The sequencing of the internally transcribed spacer regions 1 (ITS 1) and 2 (ITS2) and the large-subunit (LSU, 28S) of the rRNA gene cluster resulted in the identification of 17 strains, three and five isolates.

Occurrence of Mycotoxigenic Species and Competitive Fungi on Preharvest Maize Ear Rot in Poland.

Maize has become one of the most important crops for food and feed production-both as a silage and crop residue worldwide. The present study aimed to identify the co-occurrence of , , , and on maize ear rot. Further, the accumulation of mycotoxins as secondary metabolites of spp.

Diversity and mycotoxin production by Fusarium temperatum and Fusarium subglutinans as causal agents of pre-harvest Fusarium maize ear rot in Poland.

Maize ear rot is a common disease found worldwide, caused by several toxigenic Fusarium species. Maize ears and kernels infected by Fusarium subglutinans contained significant amounts of beauvericin, fusaproliferin, moniliformin, and enniatins. In 2011, F.

Trichoderma species occurring on wood with decay symptoms in mountain forests in Central Europe: genetic and enzymatic characterization.

The aim of this study was to explore the species diversity of Trichoderma obtained from samples of wood collected in the forests of the Gorce Mountains (location A), Karkonosze Mountains (location B) and Tatra Mountains (location C) in Central Europe and to examine the cellulolytic and xylanolytic activity of these species as an expression of their probable role in wood decay processes. The present study has led to the identification of the following species and species complex: Trichoderma atroviride P. Karst.

Zearalenone lactonohydrolase activity in Hypocreales and its evolutionary relationships within the epoxide hydrolase subset of a/b-hydrolases.

Background: Zearalenone is a mycotoxin produced by several species of Fusarium genus, most notably Fusarium graminearum and Fusarium culmorum. This resorcylic acid lactone is one of the most important toxins causing serious animal and human diseases. For over two decades it has been known that the mycoparasitic fungus Clonostachys rosea (synonym: Gliocladium roseum, teleomorph: Bionectria ochroleuca) can detoxify zearalenone, however no such attributes have been described within the Trichoderma genus.
