| 摘 要： | 利用SAS软件的Plackett-Burman设计法对微生物固态发酵脱毒棉酚的发酵参数进行筛选,得出3个影响较大的重要因素,即料水比、发酵时间、装料量,再用SAS软件二次响应面分析法进行回归分析,得到了各因素的优化水平值,经过响应面法的优化,脱毒事提高近20%。

| Abstract: | Plackett—burman and response surface analysis method were applied to optimize fermentation of biodegradation of gossypol in cottonseed meal.The results indicated the detoxification rate was mainly in- fluenced by water and material ratio,material addition,and fermentation time by Plackett—burman.In the second step,the levels of those three main factors were further optimized by using Box—Behnken design. The optimal levels of the variables were:water and material ratio 1:0.94,material addition 30.96g,fer- mentation time 62.33h.Under the optimal conditions,the detoxification rate increased by 15%.Moreover, the experiment values from optimized three batches fermentation was quite close to the expected values. |
