脱氮硫杆菌的筛选及其对锶离子的矿化作用
Isolation and Strontium Mineralization of Thiobacillus Denitrificans
摘要
Abstract
Radioactive pollution is increasingly serious, and strontium contamination is a research hot point as one of the typical radioactive pollution.There are some mineralization bacteria in soil which can immobilize the heavy metal ion in the soil.3 strains was isolated from soil and its characterization and mineralization to Sr2+ was carried on.Results show that the removal rate of strains to 1.0 g/L simulated Sr2+ is up to 80%.Scanning electron microscope(SEM), energy spectrum analysis(EDS), X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR) results show that mineral products is strontium sulfate.This study demonstrate that using Thiobacillus denitrificans for Sr2+ pollution removal in the soil is feasible, and the method will have some application prospect.关键词
