| 摘 要： | 通过Plackett-Burman试验设计方法和DPS v7.05统计软件中的均匀设计方法研究了盐类物质对棉粕发酵底物中游离棉酚降解率的影响。Plackett-Burman试验结果表明只有生物素对降解率的影响是极显著的,其他因素均不显著,进而不能进一步通过Box-Behnken(BBD)实验来验证此试验结果。因此选出对降解率具有正效应的因素利用DPS v7.05统计软件中的均匀设计方法来研究这些因素对降解率的影响。最后得出各个因子的最佳组合:X_1(尿素)1.44%,X_2(柠檬酸三铵)0.20%,X_3(氯化胆碱)0.20%,X_4(磷酸氢二钾)0.34%,X_5(硫酸镁)1.00%,X_6(硫酸铜)1.00%,X_7(硫酸锰)1.00%,X_8(硫酸锌)0.10%。

| Abstract: | This paper studies the effect of saline material on the degradation rate FG of cottonseed meal fermentation by Plackett-Burman experimental design methods and statistical software DPS v7.05 uniform design method. Plackett-Burman experimental results show that only biotin extremely significant affects degradation rate, other factors are not significant, and thus can not be further tests to verify the results by Box-Behnken (BBD) experiments. To study the impact of these factors on the degradation rate of the selected factors and therefore a positive effect on the degradation rate of the use of statistical software DPS v7.05 uniform design method. Finally, the best combination is obtained for each factor: X1(Urea) 1.44%, X2(Ammonium Citrate) 0.20%, X3(Choline Chloride) 0.20%, X4(Dipotassium Hydrogen Phosphate) 0.34%, X5(Magnesium Sulphate) 1.00%, X6(Copper Sulfate) 1.00%, X7(Manganese Sulfate) 1.00%, X8(Zinc Sulfate) 0.10%. |
