Study on arsenic resistance of the selected microorganisms in environment

Objective To investigate arsenic resistance of the selected microorganisms in environment.Methods The selected microorganisms were cultivated at 37℃ in culture media that was put different concentration of sodium arsenite,and detected arsenic accumulation in cells by ASA.Results Coliform bacterium,Staphylococcus albus,Cerea bacillus,Bacillus aeruginosus and yeast fungus can grow when incubated in medium containing 1 000 mg/L arsenite.Conclusion The strains tested in the study have the ability of resistance to arsenic.
