The presence of amino acids on the prebiotic Earth, either stemming from endogenous chemical routes or delivered by meteorites, is consensually accepted. Prebiotically plausible pathways to peptides inactivated are still unclear as most oligomerization approaches rely thermodynamically disfavored reactions in solution. Now, a combination prebiotically minerals and mechanochemical activation ena...
an 84-day feeding trial was carried out onfingerling (4.44 ± 0.06 g) rainbow trout (oncorhynchusmykiss, walbaum, 1792) to evaluate the effect of dietary supplementation with a commercial prebiotic grobiotic®-a (g-a) on the growth, feed efficiency, haematology and immunlogical parameters. ttreatments containing various inclusions of g-a (0 %, 0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %) were ad...
this study was carried out to determine the effects of immunogen as a prebiotic on growth-related parameters and gut micro-flora in r. kutum fry. a basal diet was formulated using common feed ingredients supplemented with immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets. fish were randomly distributed in 500 l fiberglass tanks (1×1×0.5 m). the experiment lasted for eight ...
The process of delineating the origins of the chemistry of life starts with the consideration of the molecules that might have existed on prebiotic earth and extends to the discussion of potential mechanisms for assembly of these molecules into informational polymers capable of self-replication and transmittance of genetic information. At some point along this pathway, the property of single ch...
Inulin-type fructans are the most studied prebiotic compounds because of their broad range of health benefits. In particular, plants of the Agave genus are rich in fructans. Agave-derived fructans have a branched structure with both β-(2→1) and β-(2→6) linked fructosyl chains attached to the sucrose start unit with a degree of polymerization (DP) of up to 80 fructose units. The objective of thi...
The potential prebiotic properties of arabino-oligosaccharides (AOS) derived from sugar beet pulp was studied using mixed cultures of human fecal bacteria from patients with ulcerative colitis (UC), in remission or with active disease, and in healthy controls. These results were compared to those for fructo-oligosaccharides (FOS), which are known to have a prebiotic effect. Fermentation studies...
