Abstract

The microbial conversion of zearalenone by various species of fungi was studied. Among them, Rhizopus sp. was the sole fungus which produced a new metabolite from zearalenone in addition to alpha- and beta-zearalenol. The structure of the new metabolite was determined to be zearalenone 4-beta-D-glucopyranoside on the basis of mass, infrared, and nuclear magnetic resonance spectroscopies. The results suggest that the mycelium of Rhizopus sp. catalyzes the glycosidation at the C-4 position of zearalenone.

摘要

研究了多种真菌对玉米赤霉烯酮的微生物转化。其中,根霉属是唯一一种除了产生α-和β-玉米赤霉烯醇外,还能从玉米赤霉烯酮产生一种新代谢物的真菌。基于质谱、红外光谱和核磁共振光谱,确定该新代谢物的结构为玉米赤霉烯酮4-β-D-吡喃葡萄糖苷。结果表明,根霉属的菌丝体催化了玉米赤霉烯酮C-4位的糖基化反应。
