Characteristics of copper binding sites in the bacteria E. coli were studied using ESR spectroscopy. It was found that these cations had high local density on the strong binding range represented by the two type sites. The former include nitrogen and

Effect of Cu2+ on E. coli respiration and the role of oxygen in toxic action of copper has been studied. Stimulation of respiration is observed at initial time after introduction of Cu2+. It is based on a nonspecific cell response to membrane damage.
