Resistant maltodextrin (RMD) is a soluble dietary fiber derived from starch that known to promote the growth of beneficial intestinal bacteria. The aim of this study is to investigate the potential prebiotic activity of RMD on the growth of Bacteroides xylanisolvens and 15 species of probiotic strains. For this, individual culture and co-culture were performed by measuring the growth rate of 15 types of probiotics and Bac. xylanisolvens . and checking symbiosis relationship between them. As results, in case of Bac. xylanisolvens , optical density reached 1.1 and pH decreased to 5.3. However, none of 15 probiotics made a growth using RMD as a sole carbon source in the medium. When co-cultures were conducted using transwell system cultivating Bac. xylanisolvens and probiotics by separating 0.2μm membrane, only Bac. xylanisolvens made a growth revealing no cross-feeding exist in between those bacteria. In conclusion, RMD showed the prebiotics effect on Bac. xylanisolvens , but not on 15 species of probiotics.
