The effect of saturated and unsaturated fatty acids on aflatoxin production was studied in a synthetic medium. The aflatoxin production decreased (10-75%) in the presence of lauric acid and palmitic acid but the addition of behenic and sebacic acid stimulated aflatoxin production by 125-541%. Linolenic and linoleic acids effected aflatoxin production and mycelium growth. An 34-fold increase in aflatoxin production was observed with 50 mM linoleic acid. An inverse relationship was observed between aflatoxin production and mycelium mass, irrespective of the nature of the fatty acid.
在合成培养基中研究了饱和脂肪酸和不饱和脂肪酸对黄曲霉毒素产生的影响。在月桂酸和棕榈酸存在的情况下，黄曲霉毒素产量下降（10 - 75%），但山嵛酸和癸二酸的添加使黄曲霉毒素产量提高了125 - 541%。亚麻酸和亚油酸影响黄曲霉毒素的产生和菌丝体生长。在50 mM亚油酸存在的情况下，观察到黄曲霉毒素产量增加了34倍。无论脂肪酸的性质如何，黄曲霉毒素产量与菌丝体质量之间均呈负相关。
