酪酸菌对肠道有益菌的增殖作用和共生关系研究

Study on proliferation effect of Clostridium butyrium on intestinal available bacteria and symbiotic relation between them

目的 通过体外液体培养证明 ,酪酸菌能与双歧杆菌、嗜酸乳杆菌和粪链球菌这些肠道有益菌共生。方法 在双歧杆菌、嗜酸乳杆菌和粪链球菌的培养基中 ,加入 1/ 3比例的酪酸菌发酵提取物 ,进行室温培养 2 4h。结果 3种菌的活菌含量分别比对照组提高了 2 4 0 0 %、4 2 5 7%和 6 76 %。结论 表明酪酸菌对肠道有益菌具有增殖作用。

Objective To observed Clostridium butyrium could accrete with many intestinal available bacteria including Bifidobacterium bifidum , Lactobacillus acidophilus and Streptococcus facealis through the liquid culture experiments in vitro . Method When Clostridium butyrium extraction was added into culture medium of Bifidobacterium bifidum,Lactobacillus acidophilus and Streptococcus facealis in proportion to 1/3 and incubated for 24 h.Results Cotent of the three live bacteria was respectively increased 24.00%,42.57% and 6.76% compared with control.Conclusion Clostridium butyrium had the proliferation action to the intestinal available bacteria.
