为找到一种脱毒较为彻底且稳定的菜籽粕脱毒方法，以复合芽孢杆菌为发酵剂，采用单因素试验研究了葡萄糖和硫酸铵添加量、料水比、接种量、起始pH、发酵温度及发酵时间等发酵条件对硫代葡萄糖苷降解率的影响。在此试验结果的基础上，采用响应面法评价了料水比、接种量、发酵温度和发酵时间及其交互作用对硫代葡萄糖苷降解率的影响，用Design Expert 7.1.6软件分析试验数据建立了菜籽粕混合菌固体发酵条件的一个二次多项式数学模型。结果表明：该模型极显著（P＜0.001），拟合度良好。得出混菌固体发酵脱毒过程的工艺参数为：接种量7.7%，发酵温度44 ℃，料水比1.000∶0.585，发酵时间53 h。在此...

In order to obtain an effective and stable method of the detoxification of rapeseed meal, the effects of fermentation conditions such as glucose addition, ammonium sulfate addition, the ratio of substrate to water, inoculation amount, initial pH value, fermentation temperature and fermentation time on the degradation rate of glucosinolate were studied by using a singlefactor test. Then, the effects of ratio of substrate to water, inocu lation amount, fermentation temperature and fermentation time and their interactions on the degradation rate o...
