In addition to reductively precipitating some contaminant
metals, dissimilatory metal reducers may solubilize or
volatilize other metal contaminants. This solubilization
makes metals easier to recover from contaminated subsurface
environments and surface soils in pump-and-treat
remediation strategies. For example, dissimilatory Fe3+
reducers may be able to reduce insoluble Pu4+ to the
more soluble Pus+ [Sl]. Furthermore, heavy metals and
radionuclides adsorbed onto insoluble Fe3+ and Mn4+
