Examination was made of the fluctuations of numbers of the total bacteria and copper (Cu)-resistant bacteria with soluble/exchangeable Cu (Ex-Cu) fraction in three types of soils spiked with Cu at four concentrations. Drastic increase in Cu-resistant bacteria was observed in three soils spiked with 20 mmol Cu kg(-1) after 2 weeks of incubation, indicating the strong selection of individuals originally resistant to Cu. Adaptation and proliferation of bacteria were also observed in the soil… CONTINUE READING
