This study provides fundamental information on the interactions between iron cycles and transformation of reducible pollutants transformation. We introduce 2 cases of microbial and abiotic interactions (
1
) Interactions between reduction of iron oxides and dechlorination of 1,1,1-trichoro-2,2-bis(
p
-chlorophenyl)- ethane (DDT) by dissimilatory Fe(III)-reducing bacterium (DIRB) S12; (
2
) Interactions among CY01, and reduction of iron oxides and reduction of 2,4-dichlorophenoxyacetic acid (2,4-D). We found that the transformation of DDT and 2,4-D could be enhanced in a system of dissimilatory iron-reducing bacteria and iron oxides. This contribution demonstrated the important role of DIRB and Fe(II)/Fe(III) cycles on the transformation of pesticides under anaerobic environments, and provided scientific information for in-situ bioremediation of pesticide pollutants in Fe(III)-rich environments.
