Abstract: After taming,Saccharomyces cerevisiae(As2.109)could be used to purify isomaltooligosacchride by its selective fermentation.The optimum conditions for isomaltooligosacchride’s purification were:pH 4.0,temperature 30～32℃,250g/L isomaltooligosacchride,0.6g/L yeast extracts,0.6g/L CO(NH2)2,0.08g/L Fe2(SO4)3，1.2g/L MgSO4.Under the optimum circumstance,after 38 hours’ fermentation,the content of isomaltooligosacchride was purified up to 90.3％from previous 53.8％,while the glucose was completely eliminated.
