禾谷镰刀菌(Fusarium graminearum)本是产生真菌毒素的粮食作物的有毒真菌.英国研究者从英本土、北美、澳大利亚和非洲收集的3000份土壤标本中筛选出高产、无毒株,在葡萄糖、生物素培基上32℃、pH4.5～7.0培养1h可增殖1倍.连续培养时,以葡萄糖为底物、加入磷酸铵、K、Mg、Fe、Mn、Cu、Ca、Co等金属离子和促进生长的物质,需氧培养,先限制葡萄糖以促其充分发挥快速生长的特点,经几小时达到
Fusarium graminearum This is a toxic fungus that produces mycotoxins in food crops.Foundation and non-virulent strains were screened from 3,000 soil samples collected from native England, North America, Australia and Africa by researchers in the United States, Biotin culture medium was incubated at 32 ℃, pH4.5 ~ 7.0 for 1h, and proliferated 1-fold.Using glucose as substrate, ammonium phosphate, K, Mg, Fe, Mn, Cu, Ca, Co and other metal ions And to promote the growth of substances, aerobic culture, first limit the glucose to promote its full rapid growth characteristics, after a few hours to reach
