Isolation and Characterization of Ureolytic Bacteria for Biosequestration of Strontium

In this study, 52 ureolytic bacterial strains were newly isolated from various environments. From these, 2 strains were selected based on their high urease activity. XRD spectra clearly showed presence of various sequestration products such as calcite and strontianite in samples. TB-22 showed 20~30%...

Summary:In this study, 52 ureolytic bacterial strains were newly isolated from various environments. From these, 2 strains were selected based on their high urease activity. XRD spectra clearly showed presence of various sequestration products such as calcite and strontianite in samples. TB-22 showed 20~30% higher survivability upon Srconcentration than Sporosarcina pasteurii KCTC 3558. TB-15 TB-22 showed 80-90% higher survivability at pH 6 than S.pasteurii. The results demonstrated that the 2 isolates colud be good candidates for the bioremediation of Sr contaminated sites.
