  • Quantification of arsenic reduction and extraction from soil samples.
  • Assessing the adsorptive properties of arsenite compared to arsenate.

    • Main Results:

    • Bacillus sp. SF-1 demonstrated effective reduction of solid-phase arsenate to arsenite.
    • The bacterium facilitated the extraction of arsenic from various contaminated solids.
    • Arsenite, the reduced form, exhibited significantly lower adsorptive properties than arsenate.
    • The strain proved to be easy to handle and a potentially cost-effective agent.

    Conclusions:

    • Bacillus sp. SF-1 is a promising candidate for the bioremediation of arsenic-contaminated soils.
    • The bacterium's mechanism involves reducing arsenate to less adsorptive arsenite, facilitating arsenic removal.
    • This novel bioremedial approach offers a sustainable and economical solution for arsenic-polluted environments.
