冷热两种方法提取的褐藻硫酸多糖促双歧杆菌增殖效果的比较

目的 比较褐灌硫酸多糖（冷提取物ＳＰＣ和热提取物ＳＰＨ）对青春双歧杆菌和婴儿双歧杆菌性外促增殖效果。方法 选用ＢＳ培养基，采取度管法。结果 在实验深度下。ＳＰＣ和ＳＰＨ对两种双歧杆菌增殖均有明显的促进作用。其活菌数，实验组与对照组比，有显著性和非常显著性差异（Ｐ〈０．０５，Ｐ〈０．０５，Ｐ〈０．００１），且呈量效关系。ＳＰＨ促菌增殖效果优于ＳＰＣ，当浓度为０．５％和１．０％时，具有显著性差异（Ｐ〉

COMPARISON OF THE BROLIFERATIVE EFFECTS OF SULFATED POLYSACCHARIDE OF SEA WEED FROM TWO EXTRACTIONS ON BIFIDOBACTERIUM

Objective To compare, in vitro, proliferative effects of the cold refinery of Sulfated polysaccharide of seaweed (SPC) on B. adolescentis and B. infantis with those of the heating refinery of SDulfated polysaccharide (SPH). Method A test for two kinds of SP effecting on B. adolescentis and B. infantis' proliferation in BS culture media in tube method. Results Under the testing concentration, both SPC and SPH can accelecate the proliferating of B. addescentis and B. infantis. There are obvious difference between test group and control group as far as the number of live bacterium is concerned with the levels of significance (P<0 05,P<0 01 and P<0 001) Furthermore, the effects parallel to SPC. Under the same concentration, the numbers of two kinds of live bacteria have no significont difference (P>0 05). Conclusion Both SPC and SPH are the effective proliferative factors for bifidobacteria. SPH is superior to SPC.
