PREBIOTICS AND PROBIOTICS [PDF]
Journal of Probiotics & Health, 2009 Intestinal flora encompasses at least 500 different types of bacteria living in symbiosis with their host. The dominant microflora in the stomach is Gram-positive bacteria; while in the distal small intestine and the colon is Gram-negative type. The most important intestinal bacteria are bacteroides, bifidobacteria, Enterobacteraceae, lactobacilli ...

Prebiotic Organic Microstructures [PDF]
Nature Precedings, 2011 AbstractMicro- and sub-micrometer spheres, tubules and fiber-filament soft structures have been synthesized in our experiments conducted with 3 MeV proton irradiations of a mixture of simple inorganic constituents, CO, N2 and H2O. We analysed the irradiation products, with scanning electron microscopy (SEM) and atomic force microscopy (AFM).

Prebiotic Chemistry of Pluto [PDF]
Astrobiology, 2019 We present the case for the presence of complex organic molecules, such as amino acids and nucleobases, formed by abiotic processes on the surface and in near-subsurface regions of Pluto. Pluto's surface is tinted with a range of non-ice substances with colors ranging from light yellow to red to dark brown; the colors match those of laboratory organic ...

Prebiotic Chemistry: The Role of Trimetaphosphate in Prebiotic Chemical Evolution
Frontiers in Chemistry, 2022 Life’s origins have always been a scientific puzzle. Understanding the production of biomolecules is crucial for understanding the evolution of life on Earth. Numerous studies on trimetaphosphate have been conducted in the field of prebiotic chemistry.

Prebiotic digestion and fermentation [PDF]
The American Journal of Clinical Nutrition, 2001 Prebiotics, as currently conceived of, are all carbohydrates of relatively short chain length. To be effective they must reach the cecum. Present evidence concerning the 2 most studied prebiotics, fructooligosaccharides and inulin, is consistent with their resisting digestion by gastric acid and pancreatic enzymes in vivo.

Is Struvite a Prebiotic Mineral? [PDF]
Life, 2013 The prebiotic relevance of mineral struvite, MgNH4PO4·6H2O, was studied experimentally as a phosphorylating reagent and, theoretically, to understand the geochemical requirements for its formation. The effectiveness of phosphorylation by the phosphate mineral, monetite, CaHPO4, was also studied to compare to the efficiency of struvite.

Gastrointestinal effects of prebiotics [PDF]
British Journal of Nutrition, 2002 The defining effect of prebiotics is to stimulate selectively the growth of bifidobacteria and lactobacilli in the gut and, thereby, increase the body's natural resistance to invading pathogens. Prebiotic carbohydrates may also have additional, less specific, benefits because they are fermented in the large intestine.

In vitro screening of probiotic lactic acid bacteria and prebiotic glucooligosaccharides to select effective synbiotics [PDF]
, 2010 Probiotics and prebiotics have been demonstrated to positively modulate the intestinal microflora and could promote host health. Although some studies have been performed on combinations of probiotics and prebiotics, constituting synbiotics, results on ...

Research Progress on the Interaction between Soybean Prebiotics and the Gut Microbiota and Its Health Effects [PDF]
Shipin Kexue, 2023 Human health is closely related to the gut microbiota. Gut microbiota disorders can lead to various diseases including colitis, food allergy, obesity, and constipation.
