摘要： To investigate the tolerance and adsorption of five heavy metal ions by radiation-resistant microbes, a radiation-resistant strain NO.9 was identified according to 16S rDNA gene sequence analysis and Biolog system, and the tolerance and adsorption to five heavy metal ions was analysed. The results showed that it had a maximum tolerance 2200mg/L to Pb2+, and it had adsorption ability to Pb2+, Cu2+, Hg2+, Zn2+ and Co2+under the situation as followes: 0.1g the amount of cells, at pH 6.0, 20 degrees C and adsorbed for 40 mm. it reached a maximum adsorption 98.9% to Pb2+, and the amount of adsorption was 39.56mg/g. It indicated the strain NO.9 had a strong tolerance and absorption to Pb2+. This assay laid a theoretical basis and technological foundation for further study of the radiation-resistant microorganisms in the heavy metal pollution.
