Identification of products produced by the anaerobic degradation of rutin and related flavonoids by <i>Butyrivibrio</i> sp. C₃

Abstract

Butyrivibrio sp. C 3 degrades rutin anaerobically to yield phloroglucinol, carbon dioxide, 3,4-dihydroxy-benzaldehyde, and 3,4-dihydroxyphenylacetic acid. The sugars are first released by intracellular glycosidases and then the heterocyclic ring of the aglycone undergoes hydrolytic cleavage. The glycosides of quercetin added to the medium are readily metabolized, but the aglycone is not.
