Abstract
Sulfate reducing bacteria were screened from the soil of Anhe tailing pond in Baoji in China. 22 Sulfate reducing bacterial strains were isolatedand their tolerance ability to cadmium and sulfate reduction capability were determined by nephelometry and barium sulfate precipitation, respectively. One strain named STP2-1-5 with higher sulfate reducing capacity were isolated and identified by 16S rRNA sequencing. Then it was treated by using Dielectric Barrier Discharge (DBD) plasma mutagenesis and their mutants called STP2-1-5(2) and STP2-1-5(4) were obtained. The datum showed that their sulfate reduction capacity increased by 0.1855 and 0.4820 than original bacteria respectively. STP2-1-5(2) and STP2-1-5(4) might be used in the cadmium contaminated soil remediation.
