mented soil and promote root elongation of H. annuus under toxic cadmium conditions. These observations prompted us to investi gate the ability of these bacteria to promote plant growth and cadmium uptake by H. annuus planted in cadmium-contaminated soil in experiments with potted plants. Before applying Micrococcus sp. or Klebsiella sp. in the pot experiment, the ability of these bacteria to survive in cadmium-contaminate soil were tested. Each bacterium was aseptically inoculated into cadmium-contam inated soil (65.2 mg kg
