Abstract
为实现甘草渣中黄酮物质的高效分离提取,选取发酵主要影响因素,以黄酮提取率为响应值,采用均匀设计法分别对黄孢原毛平革菌(PC菌)与纤维素分解真菌Q59、云芝与Q59两组混合发酵处理进行优化。结果显示,PC+Q59处理黄酮得率的理论最优组合为:每10g甘草渣中接种PC菌0.5mL,接种Q592mL,发酵温度为30℃,发酵料含水率61%,氮源酒石酸铵的浓度为0.4g/L,发酵时间3d,预测黄酮得率为1.59%;云芝+Q59处理黄酮得率的理论最优组合为:每10g甘草渣中接种直径为0.6cm云芝菌块5块,接种Q592mL,发酵温度为28℃,发酵料含水率67%,氮源浓度为0.1g/L,发酵时间3d,预测黄酮得率为1.25%。验证结果与预测值接近,PC+Q59、云芝+Q59两处理的实际黄酮得率分别为1.51%、1.29%,分别比乙醇直接提取法提高了156.45%、108.06%。
