Citric acid production.
Citric acid is a commodity chemical produced and consumed throughout The World. It is used mainly in the food and beverage industry, primarily as an acidulant. Although it is one of the oldest industrial fermentations, its World production is still in rapid increasing. Global production of citric acid in 2007 was over 1.6 million tones. Biochemistry of citric acid fermentation, various microbia...
متن کاملCitric Acid Determination
Three types of methods have been proposed for the determination of citric acid in urine. Salant and Wise (1) used the unspecific mercuric sulfate reagent of Deniges (2) in a study of the toxicity of citrates. Thunberg (3) developed an enzymatic method employing a dehydrogenase said to be specific for citrate. The remaining methods depend on the so called pentabromoacetone method of Stahre (4), ...

pyruvate via the Krebs citric acid cycle. Elliot and Grieg (2) concluded that tumor slices converted little or no pyruvate to succinate. They observed the disappearance of keto-acids, but not acid groups, when oxalacetate or pyruvate was added to the media. The observation that little succinate accumulated in the presence of pyruvate and mabonate must be discounted, because at that time the rol...
متن کاملChromatographic Determination of the Acids of the Citric Acid Cycle in Tissues* by Charles
Many methods are to be found in the literature for the determination of several of the individual acids of the “citric acid cycle;” however, to date no method has been available for the simultaneous determination of all of the acids in a single sample of tissue. Isherwood (1) employed partition chromatography on silica gel to separate and determine subsequently a group of acids present in fruit...
