摘要

Prebiotic inulin-type fructans (ITF) display a bifidogenic and butyrogenic effect. Four bifidobacterial strains (Bifidobacterium breve Yakult, Bifidobacterium adolescentis LMG 10734, Bifidobacterium angulatum LMG 11039(T), and Bifidobacterium longum subsp. longum LMG 11047), displaying different ITF degradation capacities, were each grown in cocultivation with Faecalibacterium prausnitzii DSM 17677(T), an ITF-degrading butyrate-producing colon bacterium, as to unravel their cross-feeding interactions. These coculture fermentations were performed in a medium for colon bacteria, whether or not including acetate (necessary for the growth of F. prausnitzii DSM 17677(T) and whether or not provided through cross-feeding), supplemented with oligofructose or inulin as the sole energy source. Bifidobacterium breve Yakult did not degrade oligofructose, resulting in the production of high concentrations of butyrate by F. prausnitzii DSM 17677(T) through oligofructose degradation. The degradation of oligofructose by B. adolescentis LMG 10734 and of oligofructose and inulin by B. angulatum LMG 11039(T) and B. longum LMG 11047 resulted in the production of acetate, which was cross-fed to F. prausnitzii DSM 17677(T), enabling the latter strain to degrade oligofructose and inulin. Slow preferential degradation of the short chain length fractions of oligofructose (intracellularly) by B. adolescentis LMG 10734 enabled substantial oligofructose degradation by F. prausnitzii DSM 17677(T). However, fast non-preferential degradation of all chain length fractions of oligofructose (extracellularly) and efficient degradation of the short chain length fractions of inulin by B. angulatum LMG 11039(T) and B. longum LMG 11047 made it impossible for F. prausnitzii DSM 17677(T) to compete for the available substrate. These results indicate that cross-feeding interactions between bifidobacteria and acetate-depending, butyrate-producing colon bacteria can be either a pure commensal or beneficial relationship between these bacteria, or can be dominated by competition, depending on the ITF degradation capacities of the bifidobacterial strains involved.
