Biotransformation of the Pentahydroxy Flavone Quercetin by Rhizobium loti and Bradyrhizobium Strains (Lotus).

J R Rao1, N D Sharma, J T Hamilton, D R Boyd, J E Cooper.   

Abstract

Lotus rhizobia catabolized quercetin in an arabinose-based medium via a novel form of C-ring cleavage, yielding phloroglucinol and protocatechuic acid. Conservation of the A and B rings of the flavone suggests that a chalcone could be formed as a transient intermediate.
