Abstract

In all the fifteen investigated Aspergillus flavus and A. parasiticus strains the maximum quantities of aflatoxins, produced on rice powder-corn steep (RC) medium, ranged from 1.17 to 23.29 times as much as those produced on yeast extract-sucrose (YES) medium. The shake cultures lowered aflatoxin formation. The maximum yields of aflatoxins did not coincide with maximum fungal growth. In most A. flavus strains investigated, the total aflatoxin content of the mycelia highly exceeded that of the culture filtrates.

摘要

在所有被研究的15株黄曲霉和寄生曲霉中，在米粉-玉米浆（RC）培养基上产生的黄曲霉毒素最大量，是在酵母提取物-蔗糖（YES）培养基上产生量的1.17至23.29倍。振荡培养降低了黄曲霉毒素的形成。黄曲霉毒素的最大产量与真菌的最大生长量并不一致。在大多数被研究的黄曲霉菌株中，菌丝体中的黄曲霉毒素总含量大大超过了培养液滤液中的含量。
