The bio-remediation of As-polluted farmlands in the arid area is seldomly reported. This
study aimed at understanding the impact of DOM, Fe-oxides, and FeOB biogeochemical …

The biogeochemistry of iron (Fe) could affect arsenic (As) fate and change its availability. Fe
(II) oxidation mediated by Fe oxidizing bacteria (FeOB) has the potential for As …

Batch bioleaching experiments were conducted using the Fe (III)-reducing bacteria,
Shewanella putrefaciens CN32, to determine the effect of the Fe (III) reduction on As …

Remediation of As (III) by use of Fe (II) oxidation bacteria (FeOB) in iron-rich soils has been
reported, but seldom used in the iron-deficient soil of arid areas. This study was aimed at …

Fe (III)(oxyhydr) oxide minerals exhibit a high sorption affinity for arsenic (As) and the
reductive dissolution of As-bearing Fe (III)(oxyhydr) oxides is considered to be the primary …

Iron oxide and oxy-hydroxide are commonly used for remediation and rehabilitation of
arsenic (As)-contaminated soil and water. However, the stability of As sequestered by iron …

Fulvic acid (FA) and iron oxides often play regulating roles in the geochemical behavior and
ecological risk of arsenic (As) in terrestrial ecosystems. FA can act as electron shuttles to …

Elevated solution concentrations of As in anoxic natural systems are usually accompanied
by microbially mediated As (V), Mn (III/IV), and Fe (III) reduction. The microbially mediated …

In arid soil with low-iron and high-calcium carbonate contents, the fate of arsenic (As) is
mainly controlled by the contents of calcium and organic matter in the soil. However, there is …

Metal-reducing bacteria play a central and important role in the biogeochemical cycle of
arsenic (As) and iron (Fe). Research on As/Fe migration from arsenic-containing iron …
