文摘

Metal(loid)-resistant bacterial strains Q2-8, Q2-13, and Q3-11 were obtained. The three strains increased the edible tissue biomass of Chinese cabbage and radish. The three strains decreased the edible tissue As or Cd content of the vegetables. The three strains decreased the DTPA-extractable Cd of the rhizosphere soils. Strains Q2-8 and Q3-11 increased the organic matter content of the rhizosphere soils.
