Abstract

In all the investigated Aspergillus ochraceus and A. alliaceus strains the maximum quantities of ochratoxins produced on yeast extract-sucrose (YES) medium exceeded that detected on wheat solid medium except A. ochraceus 67. The shake cultures lowered ochratoxins formation. The maximum yields of ochratoxins did not coincide with maximum fungal growth. In most A. strains investigated, the total ochratoxin contents of the culture filtrates highly exceeded that of the mycelia.

摘要

在所有被研究的赭曲霉和蒜曲霉菌株中，除了赭曲霉67之外，酵母提取物 - 蔗糖（YES）培养基上产生的赭曲霉毒素最大量超过了在小麦固体培养基上检测到的量。振荡培养降低了赭曲霉毒素的形成。赭曲霉毒素的最大产量与真菌的最大生长不一致。在大多数被研究的曲霉菌株中，培养滤液中的总赭曲霉毒素含量大大超过了菌丝体中的含量。
