Oxalate Degradation by Microbes of the Large Bowel of Herbivores: The Effect of Dietary Oxalate

Abstract
Rates of oxalate degradation by microbes in gastrointestinal contents from rabbits, guinea pigs, swine, and a horse increased after addition of oxalate to diets. A similar response was previously observed with ruminal microbes from cattle and sheep. Bacteria that utilize oxalate for growth appear to be selected by increased levels of dietary oxalate.
