Pseudomonas solanacearum degrades catechin to phloroglucinolcarboxylic acid, protocatechuic acid, catechol, phloroglucinol, resorcinol and hydroxyquinol, which is plasmid‐encoded. This dissimilatory plasmid, designated as pAMB1, was effectively cured by mitomycin C treatment and was transferred to a Pseudomonas sp., with a transfer frequency of 2.2 × 10 −5 transconjugants/donor cell. The cured strains did not utilize catechin or its intermediates, and lacked the plasmid.
