Abstract
Galactomannans from sources like guar, fenugreek, locust bean, and copra form an important part of human diet. In this study, we have attempted to understand the cross-feeding and resource sharing between a generalist degrader and probiotic utilizers for utilizing dietary galactomannans. In mono-cultures, Bacteroides ovatus DSMZ 1896 grew maximally on substituted galactomannans and produced high amount of succinate. Polysaccharide break down products [β-manno-oligosaccharides; degree of polymerization (DP) 2–4] left after the growth of B. ovatus DSMZ 1896 in galactomannan supplemented media supported the growth of Lactiplantibacillus plan�tarum WCFS1 (DP2 and DP3) and Bifidobacterium adolescentis DSMZ 20083 (majorly DP3) and led to the pro�duction of lactate and acetate, respectively as the major end products. Co-cultures (bi- and tri-cultures) studies demonstrated cross-feeding being used as a strategy for resource sharing among B. ovatus DSMZ 1896, L. plantarum WCFS1 and B. adolescentis DSMZ 20083 while foraging galactomannans. Structure and DP of gal�actomannan substrates altered the SCFA and organic acid production patterns in co-cultures.
