Studies on Dehydroascorbic Acid Reductase in Escherichia Colik12

“…Kendall et al (15), confirmed the fact that Mucosus capsulatus and enterococci have a strong property of destroying ascorbic acid and that the acid is destroyed prior to dehydroascorbic acid. The decomposition by these intestinal bacteria can bring about the deficiency of ascorbic acid clinically (16)(17).…”

Reduction of Dehydroascorbic Acid With Pyruvate Oxidase System

“…Kendall et al (11) confirmed the fact that Mucosus capsulatus and enterococci have a strong property of destroying ascorbic acid and the acid is destroyed fur ther through dehydroascorbic acid. The decomposition by these intestinal bacteria can bring about the deficiency of ascorbic acid clinically (12)(13) .…”

Interactions Between Ascorbic Acid and Bacteria

“…Because ascorbic acid undergoes oxidation in aqueous solution with the formation of dehydroascorbic acid and hydrogen peroxide, and as bacterial cultures frequently attain low O/R potentials, it is not surprising that several workers have found that often bacteria which do not destroy ascorbic acid have a protective effect upon it (9,10,11,21,50). Organisms which have been found to act in this way include species of Proteu, Alcaligenes, Micrococcus, Staphylococ-CUS, Pseudomonas, Bacillus, Aerobacter, Salmonella and Escherichia.…”

“…This ability seems to be a characteristic of strains rather than of species (table 2-cf. the destruction of ascorbic acid; 21,51).…”
