volatile fatty acids การใช้

• These features increase the surface area of the reticulorumen wall, facilitating the absorption of volatile fatty acids.
• Microbial fermentation degrades otherwise indigestible polymers in the reticulorumen to volatile fatty acids ( VFAs ), methane, and carbon dioxide.
• The compartments aim is to anaerobically transform this waste to ammonium, H 2, CO 2, volatile fatty acids and minerals.
• Selective precipitation with ammonium sulfate, opposite to the usual precipitation technique which uses acetic acid, does not interfere with the determination of volatile fatty acids.
• Activity of various rumen organisms results in accumulation of various volatile fatty acids ( normally, mostly acetic, propionic, and butyric acids ), which are partially dissociated.
• Other molecules, such as volatile fatty acids ( VFAs ) with a chain length greater than that of acetate must first be catabolised into compounds that can be directly used by methanogens.
• A theoretical maximum of 4 mol H2 / mol glucose can be produced and, besides hydrogen, sugars are converted to volatile fatty acids ( VFAs ) and alcohols as by-products during this process.
• In the large, multicompartmental forestomach, microorganisms ferment plant cellulose and release volatile fatty acids; the acids come into contact with cells with a large surface area that absorb them to provide much of the energy supply.
• Though its functions have not been well-studied, it appears to primarily aid in the absorption of water, magnesium, and the volatile fatty acids produced by rumen fermentation, that have not been absorbed into the bloodstream yet.
• Fibre, especially cellulose and hemi-cellulose, is primarily broken down into the volatile fatty acids, acetic acid, propionic acid and butyric acid in these chambers ( the reticulo-rumen ) by microbes : ( bacteria, protozoa, and fungi ).
• Their fore stomach has fermentation carried out by microbes and has high levels of volatile fatty acid; it has been proposed that their complex fore stomach is a means to slow digestive passage and increase digestive efficiency.
• Insoluble carbohydrates, such as fiber ( cellulose ), are not digested by the horse's own enzymes, but are fermented by microbes in the cecum and large colon to break down and release their energy sources, volatile fatty acids.
• By further reduction of the rosin content to 1-10 %, " tall oil fatty acid " ( " TOFA " ) can be obtained, which is cheap, consists mostly of oleic acid, and is a source of volatile fatty acids.
• Once within microbial cell walls, the mono-and disaccharides may be assimilated into microbial biomass or fermented to volatile fatty acids ( VFAs ) valerate and other branched-chain VFAs via glycolysis and other biochemical pathways to yield energy for the microbial cell.
• In the analysis of rubber lattices, volatile fatty acids are analyzed by precipitating rubber with a 35 % ammonium sulfate solution, which leaves a clear liquid from which volatile fatty acids are regenerated with sulfuric acid and then distilled with steam.
• In the analysis of rubber lattices, volatile fatty acids are analyzed by precipitating rubber with a 35 % ammonium sulfate solution, which leaves a clear liquid from which volatile fatty acids are regenerated with sulfuric acid and then distilled with steam.
• Fiber, especially cellulose and hemicellulose, is primarily broken down in these chambers by microbes ( mostly bacteria, as well as some protozoa, fungi and yeast ) into the three volatile fatty acids ( VFAs ) : acetic acid, propionic acid, and butyric acid.
