Effect of human faecal inoculum on in vitro fermentation variables.
1. Homogenized and diluted faeces (66.6 g/l) collected from one human source on three different months was incubated with four standard substrates (oat bran, wheat bran, red kidney beans (Phaseolus vulgaris) and guar gum) for 4, 8, 12 and 24 h. 2. Neutral-detergent fibre and organic matter (OM) digestibility measurements and gas production (ml gas/g OM) were influenced by substrate and incubati...
متن کاملFermentation of non-digestible oligosaccharides by human colonic bacteria.
The principal substrates for colonic bacterial growth are dietary carbohydrates which have escaped digestion in the upper gastrointestinal tract. These may be starches, dietary fibres, other non-absorbable sugars, sugar alcohols and oligosaccharides. In the large intestine, saccharolytic bacteria are able to metabolize carbohydrates for increased energy and growth with short-chain fatty acids (...
متن کاملIn vitro fermentation of sugar beet arabinan and arabino-oligosaccharides by the human gut microflora.
AIMS To determine the fermentation profiles by human gut bacteria of arabino-oligosaccharides of varying degree of polymerization. MATERIALS AND METHODS Sugar beet arabinan was hydrolyzed with a commercial pectinase and eight fractions, of varying molecular weight, were isolated by gel-filtration chromatography. Hydrolysis fractions, arabinose, arabinan and fructo-oligosaccharides were fermen...
متن کاملFermentation properties and potential prebiotic activity of Bimuno® galacto-oligosaccharide (65 % galacto-oligosaccharide content) on in vitro gut microbiota parameters
Prebiotic oligosaccharides have the ability to generate important changes in the gut microbiota composition that may confer health benefits to the host. Reducing the impurities in prebiotic mixtures could expand their applications in food industries and improve their selectivity and prebiotic effect on the potential beneficial bacteria such as bifidobacteria and lactobacilli. This study aimed t...
متن کاملIn situ prebiotics for weaning piglets: in vitro production and fermentation of potato galacto-rhamnogalacturonan.
Postweaning diarrhea (PWD) in pigs is a leading cause of economic loss in pork production worldwide. The current practice of using antibiotics and zinc to treat PWD is unsustainable due to the potential of antibiotic resistance and ecological disturbance, and novel methods are required. In this study, an in vitro model was used to test the possibility of producing prebiotic fiber in situ in the...
