Abstract
In this study, were investigated the yields and prebiotic effects of exopolysaccharides（EPS）produced by Lactic acid bacteria grown in MRS media on the growth of Bifidobacteria. Choose one lactic acid bacteria whose EPS have the best prebiotic effects. Test the yields and prebiotic effects of the EPS produced by this lactic acid bacteria grown in modified-MRS media which contain 10% various sugars and compare to fructooligosaccharides（FOS）. Finally analyze the composition of EPS. The results indicated that the yields of EPS produced by LAB grown in MRS media were from Lactobacillus plantarum BCRC 11697（930 mg/L）, L. delbrueckii subsp. bulgaricus BCRC 10696, L. rhamnosus GG BCRC 16000, L. casei, L. fermentum, L. helveticus, L. acidophilus BCRC 14079 to L. salivarius BCRC14759 ( 450 mg/L）. Prebiotic effects of EPS produced by Lactobacillus acidophilus BCRC 14079 and L. casei were better than L. helveticus and L. salivarius BCRC14759. Prebiotic effects of EPS produced by L. casei grown in MRS-glc media toward B.infantis BCRC14602, B. adolescentis BCRC14606, and B. bifidum BCRC14615 were better than FOS. Prebiotic effects of EPS produced by L. casei grown in MRS-fru media toward B. longum BCRC14634 and B. lactis Bb-12 were better than FOS. EPS produced by LAB were heteropolysaccharides and contains 50% galactose, from 14% to 40% glucose and other sugars. EPS produced by L. casei grown in modified-MRS media which contain 10% various sugars were heteropolysaccharides and contains from 60% to 80% galactose, from 14% to 30% glucose and other sugars.
