筛选出了在菜粕上生长旺盛,能有效降低硫苷和粗纤维含量的高效降解菌株--枯草芽孢杆菌B_3、纳豆芽孢杆菌N_1和酿酒酵母R_1,并进行单菌、混菌发酵实验.结果表明,混株发酵效果优于单菌株发酵,恶唑烷硫酮(OZT)及异硫氰酸酯(ITC)的降解率分别达到70.75%、82.14%;植酸、芥子碱、中性洗涤纤维分别减少71.37%、70.88%和26.12%;菜籽饼粕中粗蛋白的含量提高了13.70%.%This paper selected the high-effective strains--Bacillus subtilis B_3 ,Bacillus natto N_1 , Saccharomyces cerevisiae R_1 , which can grow vigorously on the rapeseed meal, effectively degrade glucosinolate and crude fiber. The results showed that the effect of mixed-strains fermentation is superior to single-strain fermentation. The degradation rate of oxazolidine thione(OZT) and isothiocyanate(ITC) reached to 70. 75% and 82. 14% ; the content of phytic acid, sinapine and neutral detergent fiber decreased by 71. 37% , 70.88% and 26. 12% respectively; the content of crude protein increased by 13. 70% in fermented rapeseed meal.
