Abstract
The current screening study aimed at testing a set of well-characterized carbohydrates derived
from pectic oligosaccharides (POS) from sugar beet for their specific effect on intestinal
microbiotas derived from healthy people and from patients suffering from the inflammatory bowel
disease designated Ulcerative Colitis (UC). Two such oligosaccharides having different degrees of
polymerization, in the following designated S1 and S2, respectively, were tested.
Small scale anaerobic fermentation studies were performed to test the effect of S1 and S2 on the
composition of the intestinal microbiotas. Changes in the microbial composition were addressed by
Denaturing Gradient Gel Electrophoresis, DGGE, using Fructo- Oligosaccharides (FOS, a goldenstandard
prebiotic) and glucose as reference substrates.
Comparison between the DGGE profiles obtained by fermentations of S1, S2 and FOS showed
that S2 produced a DGGE profile different from fermentations of S1 and the control substrate FOS
in a Pearson correlation cluster analysis, indicating that the degree of polymerization (DP) was
decisive for which bacteria were stimulated by the oligosaccharides.
Additionally, DGGE results of this screening study showed that there were no significant
differences between the numbers of bands in the fermentations of all four substrates, indicating
that S1, S2 and FOS had similar degrees of selectivity.
