surface multiplication factor method

Cultivated three kinds of lactic acid bacteria(LAB) in order to searching for the multiplication factors.

确定了提取姬松茸多糖的最佳工艺参数,即温度100℃,时间5h,pH值为10;研究了多糖对乳酸菌生长的影响,采用DEAE-纤维素柱层析分离姬松茸粗多糖,得到3种多糖,通过对乳酸菌的培养寻找增殖因子;测定乳酸菌的生长曲线、菌液OD值与pH值,比较了3种多糖对乳酸菌的促生长作用的差异。

It cultivated two kinds of lactic acid bacteria(LAB) with a kind of special medium which was added with 1 percent of PS as multiplication factor,cultivated at 37℃ and compared with blank sample.

实验采用DEAE-纤维素柱层析法分离食用菌提取物,得到3种多糖,通过对在培养乳酸菌的MRS培养基中添加1%3种多糖作为增殖因子,并作空白对照,37℃恒温培养,测定乳酸菌的生长曲线、菌液OD值与pH值,比较3种多糖对乳酸菌的促生长作用的差异得出,多糖Ⅰ、多糖Ⅱ对乳酸菌的增殖作用比较明显,多糖Ⅲ的增殖作用因大分子多糖与蛋白-多糖复合物含量较大而次之,但是3种多糖培养乳酸菌对数期期间活菌数都达到了1010cfu/mL以上,培养终止时间为12h。
