removal of selenium by co-precipitation with microbially induced calcite precipitation
Microbially induced calcite precipitation is a process during which bacterial activity results in the formation of calcium carbonate. Metal contaminants found in ground water, such as strontium or cadmium, can get incorporated into the calcium carbonate crystals.
Neerja Zambare, a graduate student at Montana State University, is investigating if selenium incorporation into calcium carbonate is possible. This has been done abiotically before but Neerja is testing this process using bacteria. If incorporation of selenium is possible, new water decontamination technologies could be developed.
