Abstract
本发明公开了一种利用三菌混合发酵制备白酒糟高蛋白鱼饲料原料的方法及其应用，属于生物技术和水产饲料加工技术领域。本发明旨在解决现有白酒糟直接用于水产饲料时蛋白质含量和品质不高、粗纤维偏高、消化利用率较低的问题。技术方案的核心是采用一种包含扣囊复膜酵母、波茨坦短芽孢杆菌和威尼斯镰刀菌的混合菌群，对白酒糟进行一步固态发酵。三者分工互补、协同增效，在不额外添加外源蛋白酶和糖化酶的条件下，显著提高发酵产物的粗蛋白含量和必需氨基酸水平。本发明还公开了由该方法制备的高蛋白鱼饲料原料，以及包含该原料的鱼饲料组合物。该方法流程简洁、原料利用率高，制得产品可作为鱼粉或部分植物蛋白源的替代原料，为白酒糟在水产饲料领域的高值化利用提供了新的技术途径。
