Microbial cleavage of zearalenone.Xenobiotica. 1988 Apr; 18(4):365-71.X
1. Zearalenone, a fungal oestrogenic compound, was subjected to microbial transformation studies. Preliminary screening with 150 fungal species showed that Gliocladium roseum was capable of metabolizing zearalenone in 80-90% yields. 2. Large-scale fermentation with G. roseum produced a 1:1 mixture of 1-(3,5-dihydroxyphenyl)-10'-hydroxy-1-undecen-6'-one and 1-(3,5-dihydroxyphenyl)-6'-hydroxy-1-undecen-10'-one. The compounds were isolated and purified at -20 degrees C, and identified using spectroscopic analysis and by comparison to products obtained from alkaline hydrolysis of zearalenone.
