The losses of benzoic acid and a homologous series of both mono- and dibasic aliphatic acids in oil shale retort water were monitored with time (21 days) in liquid culture (4% retort water, vol/vol) inoculated with soil. The organic acids constituted approximately 12% of the dissolved organic carbon in retort water, which served as the sole source of carbon and energy in these studies. The leve...
This study was conducted to evaluate effects of an organic acid at three levels of dietary electrolyte balances (DEB) on growth performance، acidity and gut microbial population of broiler chickens. A total of 720 as-hatched Ross 308 broilers were used in the study from day 1 old to 40 days of age. The experiment was carried out using a complete block design with factorial arrangement (2×3)....
The separation of organic acids and their elution from silicic acid columns and their quantitative measurement by color change of buffered indicator, a technique mechanized by Kesner and Muntwyler, are applicable to the study of biological materials. As little as 25 g of acid can be measured. Elution times and color yield in terms of peak areas obtained with the commercial apparatus are given f...
