Access from EThOS:
An investigation was carried out to ascertain the effects of Cu 2+, Ni t+, Cd2+ and Zn on the growth and metabolism of Nitrobacter. The effects of selected cations on the growth inhibitory action produced by the above metals, the uptake of these metals and heavy metal resistance in Nitrobacter were also studied. It was concluded that Cut+, Cd2+ and Znt+ uncoupled oxidative phosphorylation from respiration and the primary site of action for these metals was the membrane system. The site of action for Ni + was the cytoplasm and toxicity was attributed to inhibition of ribulose-1,5-diphosphate carboxylase. Tolerance to Cu 2+' Ni t+, Cdt+ or Znt+ could not be induced.
