Plasmid-determined resistance to Hg(II) and to organomercurials was described in both Escherichia coli and Pseudomonas aeruginosa. Pseudomonas aeruginosa was able to grow at 5-10 ..mu..M phenylmercuric acetate (PMA) and reduced Hg/sup 2 +/ in media containing 1-20 ..mu..M of this compound. Escherichia coli reduced 95% of 5 ..mu..M PMA and growth of the cells began after the elimination of PMA from the medium. The findings of the reduction or organomercurials by plasmid-carrying E. coli and the ability of a plasmid-borne gene in P. aeruginosa to reduce organomercurials are reported for the first time. 31 references, 4 figures.
