@entity1042 production from the degradation of pectin by XXXX colonic bacteria.

@entity1 @entity17367 @entity1042 @entity2716 @entity15394 @entity413 @entity165
When ingested, pectin can lower serum @entity165 levels in @entity1 . Pectin is degraded by fecal bacteria in the colon. We examined the release of @entity1042 ( @entity2716 ) by this degradation. A 0.2% @entity413 (2 g/L) mixture was used as the control medium. A pure culture of pectinolytic @entity17367 was the control bacterium. The chief substrates were, in set 1, 0.2% pectin (2 g/L) and, in set 2, 0.1% @entity413 (1 g/L) and 0.1% pectin (1 g/L). Cultures of fecal bacteria and @entity17367 grew for 72 h in each of the solutions. By 72 h the fecal flora culture in set 1 cleaved 30% of the possible @entity15394 groups on pectin. The fecal flora in set 2 cleaved 90.7% of all possible @entity15394 groups. Balance studies suggest that all of the free @entity2716 comes from @entity15394 groups on pectin. This study demonstrates that fecal bacteria are capable of degrading pectin to release @entity2716 .
