银耳浅红酵母病(俗称红银耳)是上海郊区最严重的银耳病害,致病菌是浅红酵母,目前还缺乏有效的防治药物。由于浅红酵母和银耳都属真菌,银耳又是一种高级滋补品,这就要求选用的药物具有专一性,且对人体无毒。我们在实验室内以平板抑菌法和银耳锯木屑瓶栽药效试验法,筛选了抗菌素469、T21、制霉菌素和2-4—氧代赖氨酸(I-677)等药物,并以I-677进行防治试验。I-677是玫瑰绿链霉菌(Streptomyces yoseviridofuscus)的抗代谢产物,结构式为:
Tremella light red yeast disease (commonly known as red white fungus) is the most serious white fungus disease in Shanghai suburbs, the pathogen is light red yeast, there is a lack of effective prevention and treatment of drugs. Because the red yeast and fungus are fungi, white fungus is a high-grade supplements, which requires the selection of drugs with specificity, and non-toxic to humans. We selected antibiotics 469, T21, nystatin and I-677 and other drugs in the laboratory by the plate antibacterial method and the white fungus sawdust bottle. I-677 for prevention and control test. I-677 is an anti-metabolite of Streptomyces yoseviridofuscus with the structural formula:
