霉菌属腐生物,靠摄取宿主的有机物生存。由于无叶绿素,故不需光线即可生长,但要求宿主供给葡萄糖、氮、硫、磷、钾、钙、镁和铁等,以作为合成其细胞成份的基本物质,轻度偏酸的环境对生长有利。曲菌是一种丝霉菌,可产生主要作用于RNA和DNA的Alfaltoxin、黄曲霉素)和Cumarin-Derirale(香豆素-衍生物),它们对肝组织具有特别的致癌能力和诱发细胞畸变的作用。曲菌普遍存在于自然界,常生存于沃土、食物、果实、谷物、种子和植物中,特别是上述物质腐败、发霉或枯萎时。动物常感染曲 Mold is a saprophytic organism, by the host of organisms to survive. Due to the absence of chlorophyll, it grows without light, but requires the host to supply glucose, nitrogen, sulfur, phosphorus, potassium, calcium, magnesium and iron, etc., as the basic material for the synthesis of its cellular components, Growth is good. Aspergillus is a filamentous fungus that produces Alfaltoxin, aflatoxin, and Cumarin-Derirale (coumarin-derivatives) that act primarily on RNA and DNA and are particularly carcinogenic to liver tissue and induce cell distortions Role. Aspergillus commonly occurs in nature, often living in fertile soil, food, fruits, grains, seeds and plants, especially when the above substances are corrupt, moldy or wilt. Animals often infected song
