摘要

(Chloro-)catechols are toxic for bacteria and higher organisms, but the mode of action is not yet clearly understood. We have compared the acute toxicity of different chlorinated catechols to Escherichia coli with membrane toxic effects, namely Narcosis and uncoupling that we have determined in an in vitro assay. In vitro membrane toxicity was quantified by measuring the Accelerated decay of the membrane potential of chromatophores isolated from Rhodobacter sphaeroides. Both acute and membrane Toxicity increased with increasing degree of chlorination.
