摘要
利用DNS法对乳酸菌发酵豆粕、菜籽粕和棉籽粕的总糖和还原糖含量进行测定,研究了不同发酵时间这3种粕类饲料总糖和还原糖含量的变化,得出乳酸菌具有较强的-半乳糖苷酶活性,能够降解总糖使得还原糖含量增加,发酵72h时,总糖的含量分别下降了17.4%、33.26%和27.35%,而还原糖含量增加了6.47倍、10.15倍和1.73倍。
The experiment used methods of 3.5-dinitrosalicylic acid colorimitry,to determine water-soluble total sugar and reducing sugar of Lactic Acid Bacteria fermentation SBM、rape-seed meal and cottonseed meal,to study the change condition of water-soluble total sugar and reducing sugar.The results showed that lactic acid bacteria had strong-galactosidase activity,could degrade water-soluble total sugar and increase reducing sugar by the time of fermentation 72h,the content of water-soluble total sugar respectively decreased 17.4%、33.26% and 27.35%,and the content of reducing respectively increased 6.47times、10.15 times and 1.73times.
