The molecular weight of dextransucrase measured by SDS-PAGE was 170 kDa ,which was similar to the enzyme from Leuconostoc mesenteroides. The enzyme had an optimum temperature between 25and 30℃ and an optimum pH of 5.4. It was relatively stable in the range of pH 5.0 to 7.0, but the stability declined rapidly as soon as the temperature rose over 35℃.

以蔗糖为底物，酶促反应的最适温度为25～30℃，最适pH值为5.4，动力学常数Km值为10.43 mmol/L；酶活在pH 5.0～8.0较为稳定，在室温（25℃）保藏4 天仍有59%的酶活力，4℃保存7周酶活力仅下降一半，但在35℃以上失活很快；Ca2+对催化作用有较大的促进，Mg2+有微弱的促进作用，K+对催化反应无影响，Cu2+的抑制作用最强。

The results indicate that different molecular weight of dextran could be obtained by direct fermentation,and the acid hydrolyzing in the old technology be avoided.The yield reached the maximum by controlling the pH value to be 8.0,and the inorganic salt could promote the growth of the Leuconostoc mesenteriodes with the effect of promotion being Mn2++Ca2+＞Mn2+＞Ca2+.

结果表明：通过定向发酵技术可得到符合要求的不同分子量的右旋糖酐，避免了老工艺中酸水解工艺；控制发酵培养基pH值为8.0，可使产率最大；无机盐离子Mn2+和Ca2+能促进L.M菌的生长，其促进菌生长的程度大小依次为：Mn2++Ca2+＞Mn2+＞Ca2+。

This study has discussed that Lactic acid bacteria are isolated from 752 samples of milk and other dairy products, collected from 500 household in pastoral areas in Inner mongolia, and its biological properties are analyzed and studied.765 strains of lactic acid bacteria, including 28 species of Lactobacellus,2 species strains of Bifidobacterium, 9 species strains of Enterococcus, 3 species strains of Lactococcus, 1 specie of Streptococcus, 6 species of Leuconostoc,1 specie of Pediococcus , are identified.

Among those results,the efficiency of leuconostoc mesentervides was the best one; and the nitrite peak was inhibited clearly by adding garlic juice or ginger juice during fermentation.

结果表明：采用纯接种技术，在发酵前期可有效降低亚硝酸盐的含量，其中以接种肠膜明串珠菌效果最佳；同时在发酵过程中添加适量蒜汁或姜汁，可明显地抑制甘蓝乳酸发酵中亚硝峰出现；且在发酵过程中，泡菜的pH值对亚硝酸盐含量也有较大的影响。

In this article, the method for detecting five kinds of biogenic amines by HPLC was established, and the contents of biogenic amines in Chinese rice wines and soy sauces were detected. In order to reduce the contents of BA, we inoculated Lactobacillus curvatus 6031 and Leuconostoc mesenteroides 51-5 D in sausage and the contents of BA and the microbial counts was studied during the fermention of sausage.
