| Research Abstract |
We investigated a novel bioremediation strategy for arsenic-contaminated soil via microbial arsenic mobilization. The results indicate that solid phase arsenate reduction by a dissimilatory arsenate-reducing bacterium is vital for effective arsenic removal from solid phase. Also, vitamin B_2 could significantly enhance arsenic mobilization as a redox active mediator, suggesting that simultaneous use of dissimilatory arsenate-reducing bacteria and vitamin B_2 can be an effective strategy for remediation of arsenic-contaminated soil.
