RESUMO
The role of cellular energy, and mainly that of electrical transmembrane potential, in cadmium fixation by a marine pseudomonad suspended in a mineral medium was investigated by studying the effects of ionophores. Although fixation of cadmium by cells was generally less when respiratory activity was inhibited, it was not affected by a reduction of the transmembrane electrical potential delta psi in mureinoplasts. These observations strongly suggest that cadmium fixation in this isolate was not the result of a delta psi-dependent active transport.
