Biodegradation
Iron minerals and the coupling of electron shuttle media can effectively overcome the problem of the insolubility of iron minerals and the higher cross-medium resistance consequently to enhance the bio-reduction rate of Cr(VI) by dissimilatory metal-reducing bacteria (DMRB).

Electron transfer mediators (ETMs) such as low-molecular-mass quinones (e.g., juglone and lawsone) and humic substances are believed to play a role in many redox reactions involved in contaminant transformations and the biogeochemical cycling of many redox-active elements (e.g., Fe and Mn) in aquatic and terrestrial environments.

The extracellular electron transfer (EET) process of Shewanella species is believed to be indispensable for their anaerobic respiration with an electrode. However, the function of outer membrane c-type cytochromes (OM c-Cyts, the primary components of the EET pathway) is still controversial.

The susceptibility of various bacteriogenic iron oxides (BIOS) to bacterial Fe(III) reduction was examined. Reduction resulted in complete dissolution of the iron mineral from the surfaces of the Fe-oxidizing consortium. Reduction rates were compared to that of synthetic ferrihydrite (HFO).

Abstract The effect of nickel on the reductive dissolution of hematite by the dissimilatory metal-reducing bacterium (DMRB) Shewanella putrefaciens CN32 was studied in batch culture mode. Experiments were conducted under nongrowth conditions (108 cell mL−1) with hematite (2.0 g L−1) in 10 mM PIPES (pH 6.8) and H2 as the electron donor, spiked with ...

Abstract This study compared the chemical and physical properties of freshwater biogenic iron oxides (BIOS) aged at 4 °C for ~ 5 years in the dark to simulate early diagenesis to previously published findings from fresh samples. In addition, the reactivity of aged BIOS in the presence of a well-characterized iron reducing bacterium, Shewanella ...

In natural reducing environments, such as anoxic sediments and soils, bacteria may be exposed to high concentrations of soluble transition metals. The aim of this study was to identify physiological and biochemical adaptations of Shewanella putrefaciens CN32 membranes to soluble Mn(II), V(IV), and U(VI).
