Abstract
Zearalenones are mycotoxins with estrogenic activity consisting of a resorcinol moiety fused to a 14-membered macrocyclic lactone and are produced by various Fusarium species. We found that Clonostachys rosea IFO 7063 was effectively capable of converting zearalenone to cleavage product, 1-(3,5-dihydroxyphenyl)-10′-hydroxy-1′E-undecene-6′-one. Moreover, the cleavage product did not show potent estrogenic activity like that of Zearalenone and 17β-estradiol in the human breast cancer MCF-7 cell proliferation assay.
