Oxidation of pyruvic acid oxime by soil organisms

“coupling” of Phosphorylation with Oxidation of Pyruvic Acid in Brain*

An analysis of the dialyzable components of the pyruvic acid oxidation system of brain showed that in addition to cocarboxylase (thiamine pyrophosphate) (2), a C, dicarboxylic acid (2), and magnesium or manganese ions (3), both inorganic phosphate and “adenine nucleotide” (adenylic acid, adenosine triphosphate) (4) are required. The latter observation suggested that a cycle of phosphorylation i...

Decomposition of Cysteic Acid and Taurine by Soil Micro - organisms

Streptomycetes and aerobic bacteria able to utilize cysteic acid and taurine as sole sources of energy, nitrogen and sulphur were isolated from soil materials. None of the isolated fungi did this. The bacterium which was used in most experiments grew on both compounds. The sulphur of the compounds was recovered as sulphate and most of the nitrogen as ammonia after breakdown by growing or pregro...

Oxidation of phenol and benzoic acid by some soil bacteria.

Photochemistry of aqueous pyruvic acid.

The study of organic chemistry in atmospheric aerosols and cloud formation is of interest in predictions of air quality and climate change. It is now known that aqueous phase chemistry is important in the formation of secondary organic aerosols. Here, the photoreactivity of pyruvic acid (PA; CH3COCOOH) is investigated in aqueous environments characteristic of atmospheric aerosols. PA is current...

The Utilization of Pyruvic Acid by Bakers’ Yeast*

If sodium pyruvate is added to cells of bakers’ yeast suspended in a phosphate buffer of pH 7.0 in the strict absence of oxygen, practically no pyruvate is utilized. After 3 hours in contact with the cells the sodium pyruvate can be almost quantitatively recovered. If, however, oxygen is admiNed to the cells, then both pyruvate and oxygen are utilized at appreciable rates (see Table I). So far ...
