MICROBIAL METABOLISM OF OXALIC ACID

The Metabolism of Oxalic Acid*

103 Abstract: Oxalic acid is a widely occurring natural product of animals, plants and other organisms. It sometimes occurs as a free acid, but more commonly as a calcium salt. Organisms exhibit various levels of oxalate content which even show fluctuations among the organs of the same individual. Although oxalate seems to engage in the metabolism and adaptation of animals, plants and fungi, it...

Oxalic acid

Reproductive toxicology. Oxalic acid.

Background: We conducted an assessment of knowledge about blood borne pathogens (BBP) and use of universal precautions at first level care facilities (FLCF) in two districts of Pakistan. Methods: We conducted a cross-sectional survey and selected three different types of FLCFs ; public, general practitioners and unqualified practitioners through stratified random sampling technique. At each fac...

The metabolism of ascorbic acid-1-C14 and oxalic acid-C14 in the rat.

It is known that oxalic acid is a product of ascorbic acid metabolism in the guinea pig (1) and rat (2), and is formed in man from unidentified precursors (3). Oxalates are also of interest because of their occasional toxicity and unexplained deposition. Ascorbic, dehydroascorbic, and 2,3diketogulonic acids are known to give rise to oxalic and threonic acids in approximately quantitative yields...

Enzymatic decarboxylation of oxalic acid.

Large quantities of oxalic acid accumulate in the cell sap of various plants and as a major product of carbohydrate metabolism by many molds. A recent investigation in our laboratory revealed that oxalic acid was produced from oxalacetic acid by an enzyme system which was isolated from the mycelia of Aspergillus niger (1). It was also demonstrated that oxalic acid was converted to formic acid a...
