Among bacteria, degradation of (+)-catechin can be achieved by Acinetobacter calcoaceticus. Catechin is metabolized toprotocatechuic acid (PCA) andphloroglucinol carboxylic acid (PGCA).[24] It is also degraded by Bradyrhizobium japonicum. Phloroglucinol carboxylic acid is further decarboxylated to phloroglucinol, which is dehydroxylated to resorcinol. Resorcinol is hydroxylated tohydroxyquinol. Protocatechuic acid and hydroxyquinol undergo intradiol cleavage through protocatechuate 3,4-dioxygenaseand hydroxyquinol 1,2-dioxygenase to formβ-carboxy cis, cis-muconic acid and maleyl acetate.
