This work focused on obtaining fermented oil cake (cotton or ) via macrofungi growth with potential characteristics for animal feed formulations, such as the presence of extracellular enzymes, bioactive (ergosterol and antioxidants), and detoxification of antinutritional compounds. The concentration of phorbol esters was reduced by four macrofungi in seed cake (JSC) to non-toxic levels. At least two macrofungi efficiently degraded free gossypol in cottonseed cake (CSC). Fermentation with sp. INPA1646 and sp. INPA1696 resulted in increased ergosterol concentrations, antioxidant activity reduction, and high activity of laccases and proteases. Bromatological analysis indicated high crude protein concentrations, with partial solubilization by fungal proteases. Fermented products from sp. and sp. in JSC or CSC can be considered important biological inputs for monogastric and polygastric animal feed.
这项工作的重点是通过大型真菌的生长来获得发酵油饼（棉花或其他），这些发酵油饼具有用于动物饲料配方的潜在特性，例如存在细胞外酶、生物活性物质（麦角固醇和抗氧化剂）以及抗营养化合物的解毒作用。四种大型真菌将棉籽饼（JSC）中的佛波酯浓度降低到了无毒水平。至少两种大型真菌有效地降解了棉籽饼（CSC）中的游离棉酚。用木霉属INPA1646菌株和曲霉属INPA1696菌株进行发酵，导致麦角固醇浓度增加、抗氧化活性降低以及漆酶和蛋白酶的高活性。饲料分析表明粗蛋白浓度很高，真菌蛋白酶使其部分溶解。JSC或CSC中木霉属和曲霉属的发酵产物可被视为单胃和多胃动物饲料的重要生物原料。
