Abstract
Cilj ovog završnog rada je predstaviti modificirane oblike mikotoksina plijesni roda Fusarium. Plijesni roda Fusarium kao sekundarne metabolite sintetiziraju mikotoksine. Najučestaliji mikotoksini plijesni Fusarium su: fumonizini, trihoteceni, zearalenon i moniliformin. Ti mikotoksini pri različitim klimatskim uvjetima podlježu tranformacijama te se sintetiziraju modificirani mikotoksini. Najčešće reakcije kojima nastaju modificirani mikotoksini su reakcije hidroksilacije, deacetilacije, acetilacije, glikolizacije i oksidacije. Na modifikaciju mikotoksina osim klimatskih uvjeta utječu nutritivni faktori i aktivitet vode. Fumonizini su velika skupina mikotoksina, ali u hrani prevladavaju fumonizini B grupe. Modifikacija fumonizina izrazito ovisi o lipidnim komponentama. Trihoteceni se dijele u dvije velike skupine: A i B. U skupinu A ubrajamo T-2 toksin i HT-2 toksin koji se povezuju sa šećerima i sulfatima te na taj način nastaju njihovi modificirani oblici. U skupinu B ubrajamo deoksinivalenol i nivalenol koji su vrlo podložni modifikaciji do koje dolazi acetilacijom i glikolizacijom. Zearalenon i njegovi modificirani oblici prestavljaju problem jer posjeduju jaku estrogensku aktivnost. Moniliformin je kiselina koja uzrokuje akutnu toksičnost. Mikotoksini i njihovi modificirani oblici i dalje su predmet istraživanja te je potrebno razviti analitičke metode kojima će se modificirani oblici moći detektirati u ispitivanom uzorku kako bi kasnije procijenili utjecaj metabolita modificiranih mikotoksina na naš organizam.
Abstract (english)
The aim of this paper is to present Fusarium spp. fungi modified mycotoxins. Fusarium spp. synthesize secondary metabolites, the most common are fumonisins, trichothecenes, zearalenone and moniliformin. These mycotoxins undergo different transformations under different climatic conditions and modified mycotoxins forms occur. The most common reactions that produce modified mycotoxins are hydroxylation, deacetylation and acetylation, glycolysis as well as oxidation reactions. In addition to climatic conditions, mycotoxin modification is influenced by nutritional factors and water activity. Fumonisins are a large group of mycotoxins, but fumonisins of group B predominate in food. Modifications of fumonisin are highly dependent on lipid components. Trichothecenes are divided into two major groups: A and B. Group A includes T-2 toxin and HT-2 toxin, which bind to sugars and sulphates and form their modified forms. Group B includes deoxynivalenol and nivalenol, which are very susceptible to modification by acetylation and glycosylation. Zearalenone and its modified forms are a problem because they possess strong estrogenic activity. Moniliformin is an acid that causes acute toxicity. Mycotoxins of Fusarium spp. fungi and their modified forms are still under the research and it is necessary to develop analytical methods by which modified forms can be detected in order to assess impact of modified mycotoxins on food safety.
