【摘要】：文章利用响应面法对毛叶山桐子发酵饲料的发酵条件进行了优化.实验菌种采用了产朊假丝酵母,实验材料为毛叶山桐子的脱脂果渣.首先利用单因素实验对五个影响发酵的指标进行了研究,然后在单因素的基础上利用Plackett-Burman实验设计筛选出其中显著的三个因子并利用Box-Behnken响应面设计对其进行优化.优化后的条件为发酵温度30℃,料液比1∶1.2,接种量10.5%,硝酸铵添加量8.8%,发酵时间4d.经优化条件发酵后,毛叶山桐子脱脂果渣发酵饲料的粗蛋白由发酵前的8.49%提升到19.13%,脱脂果渣的营养组成变得更加合理.
[Abstract]:The fermentation conditions of Tongzi fermented feed were optimized by response surface method. Candida prion was used in the experiment, and the defatted fruit residue was used in the experiment. Firstly, five factors affecting fermentation were studied by single factor experiment, and then three significant factors were selected by Plackett-Burman experimental design on the basis of single factor and optimized by Box-Behnken response surface design. The optimized conditions were as follows: fermentation temperature 30 鈩，
