The effects of cereal substrate and temperature on production of beauvericin, moniliformin and fusaproliferin by Fusarium subglutinans ITEM-1434

Abstract

One strain of Fusarium subglutinans (ITEM-1434) isolated from maize ear rot in Poland was tested for the ability to synthesize moniliformin (MON), beauvericin (BEA) and fusaproliferin (FP) on six cereal substrates (wheat, rye, barley, oat, maize and rice kernels) for 3 weeks at 25oC and on rice at three different temperatures (20, 25 and 30oC). Most MON (497 mug/g) was produced on rice; most BEA (704 mug/g) on wheat or rice, and most FP (422 mug/g) on rye. When cultured on rice, F. subglutinans produced the highest levels of BEA and FP at 20-25oC, while MON production was best at 30oC.
