Carbon nanotubes mediating nano α-FeOOH reduction by Shewanella putrefaciens CN32 to enhance tetrabromobisphenol A removal

Science of The Total Environment, 2021
Carbon nanotubes (CNTs) mediation of the reduction of nano goethite (α-FeOOH) by Shewanella putrefaciens CN32 to improve the removal efficiency of tetrabromobisphenol A (TBBPA) was investigated in this study. The results showed that CNTs effectively promoted the biological reduction of α-FeOOH by strengthening the electron transfer process between ...

EDDS enhanced Shewanella putrefaciens CN32 and α-FeOOH reductive dechlorination of carbon tetrachloride

Chemosphere, 2018
S,S-ethylenediamine-N,N-disuccinic acid (EDDS) enhanced reductive dissolution of α-FeOOH by Shewanella putrefaciens CN32 (CN32), resulting in formation of surface-bound Fe(II) species (FeIIEDDS) to improve reductive dechlorination of carbon tetrachloride (CT).

Simultaneous Release of Fe and As during the Reductive Dissolution of Pb–As Jarosite by Shewanella putrefaciens CN32

Environmental Science & Technology, 2012
Jarosites are produced during metallurgical processing, on oxidized sulfide deposits, and in acid mine drainage environments. Despite the environmental relevance of jarosites, few studies have examined their biogeochemical stability. This study demonstrates the simultaneous reduction of structural Fe(III) and aqueous As(V) during the dissolution of ...

Flavin mononucleotide mediated microbial fuel cell in the presence of Shewanella putrefaciens CN32 and iron-bearing mineral

Biotechnology and Bioprocess Engineering, 2015
We investigate the workability of electron transfer mediators (ETMs) for the enhanced microbial fuel cell (MFC) operated by Shewanella putrefaciens CN32. In open-circuit, natural ETMs showed 128 ~ 166% of enhancement in the difference of electrical potential compared to that without ETMs (0.41 V), while MFC with synthetic ETMs achieved 200 ~ 250% of ...

Intracellular Precipitation of Pb by Shewanella putrefaciens CN32 during the Reductive Dissolution of Pb-Jarosite

Environmental Science & Technology, 2009
Jarosites (MFe(3)(SO(4))(2)(OH)(6)) are precipitated in the Zn industry to remove impurities during the extraction process and contain metals such as Pb and Ag. Jarosite wastes are often confined to capped tailings ponds, thereby creating potential for anaerobic reductive dissolution by microbial populations.

AQDS-functionalized biochar enhances the bioreduction of Cr(VI) by Shewanella putrefaciens CN32

Chemosphere
The bioreduction of toxic chromium(VI) to sparingly soluble chromium(III) represents an environmentally friendly and cost-effective method for remediating Cr contamination. Usually, this bioreduction process is slow and requires the addition of quinone compounds as electron shuttles to enhance the reaction rate. However, the dissolved quinone compounds

Iron(III)-Bearing Clay Minerals Enhance Bioreduction of Nitrobenzene by Shewanella putrefaciens CN32

Environmental Science & Technology, 2015
Iron-bearing clay minerals are ubiquitous in the environment, and the clay-Fe(II)/Fe(III) redox couple plays important roles in abiotic reduction of several classes of environmental contaminants. We investigated the role of Fe-bearing clay minerals on the bioreduction of nitrobenzene. In experiments with Shewanella putrefaciens CN32 and excess electron

Effect of Natural Organic Matter on Zinc Inhibition of Hematite Bioreduction by Shewanella putrefaciens CN32

Environmental Science & Technology, 2007
The effect of zinc on the biological reduction of hematite (alpha-Fe2O3) by the dissimilatory metal-reducing bacterium (DMRB) Shewanella putrefaciens CN32 was studied in the presence of four natural organic materials (NOMs). Experiments were performed under non-growth conditions with H2 as the electron donor and zinc inhibition was quantified as the ...

Biochar mediates activation of aged nanoscale ZVI by Shewanella putrefaciens CN32 to enhance the degradation of Pentachlorophenol

Chemical Engineering Journal, 2019
Abstract The bioreduction of aged nanoscale zero valent iron (NZVI) by Shewanella putrefaciens CN32 (CN32) in the presence of different biochar materials was conducted to understand how biochars mediated the activation of aged NZVI to enhance the removal efficiency of contaminants.
