TLDR
Washed cell suspensions of Desulfovibrio vulgaris rapidly reduced Cr(VI) to Cr(III) with H(2) as the electron donor and the c(3) cytochrome from this organism functioned as a Cr( VI) reductase.Abstract:
Washed cell suspensions of Desulfovibrio vulgaris rapidly reduced Cr(VI) to Cr(III) with H2 as the electron donor. The c3 cytochrome from this organism functioned as a Cr(VI) reductase. D. vulgaris may have advantages over previously described Cr(VI) reducers for the bioremediation of Cr(VI)-contaminated waters.read more

The ecology and biotechnology of sulphate-reducing bacteria
Gerard Muyzer,Alfons J. M. Stams +1 more
TL;DR: Sulphate-reducing bacteria are anaerobic microorganisms that use sulphate as a terminal electron acceptor in, for example, the degradation of organic compounds, and are ubiquitous in anoxic habitats.

Dissimilatory Fe(III) and Mn(IV) reduction.
TL;DR: The ability to oxidize hydrogen with the reduction of Fe(III) is a highly conserved characteristic of hyperthermophilic microorganisms, most notably those in the Geobacteraceae family as mentioned in this paper.

TL;DR: The interactions of bacteria, algae, fungi and plants with Cr and its compounds are summarized and proposed as potential biotechnological tools for the bioremediation of Cr pollution.

Geobacter sulfurreducens sp. nov. , a hydrogen- and acetate-oxidizing dissimilatory metal-reducing microorganism
TL;DR: The ability to utilize either hydrogen or acetate as the sole electron donor for Fe(III) reduction makes strain PCA a unique addition to the relatively small group of respiratory metal-reducing microorganisms available in pure culture.
Journal ArticleDOI
Microbial reduction of metals and radionuclides.
TL;DR: This review focuses on recent research on the reduction of a wide range of metals including Fe(III), Mn(IV) and other more toxic metals and metalloids including As(V) and Se(VI) and radionuclides and possible biotechnological applications that could utilise these activities.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.
Journal ArticleDOI
Dissimilatory Metal Reduction
TL;DR: Microorganisms can enzymatically reduce a variety of metals in metabolic processes that are not related to metal assimilation, including technetium, vanadium, molybdenum, gold, silver, and copper, but reduction of these metals has not been studied extensively.

Reduction of uranium by Desulfovibrio desulfuricans.
TL;DR: The results indicate that enzymatic U(VI) reduction by sulfate-reducing microorganisms may be responsible for the accumulation of U(IV) in sulfidogenic environments and D. desulfuricans might be a useful organism for recovering uranium from contaminated waters and waste streams.
Journal ArticleDOI
Enzymatic iron and uranium reduction by sulfate-reducing bacteria
TL;DR: The potential for sulfate-reducing bacteria (SRB) to enzymatically reduce Fe(III) and U(VI) was investigated in this paper, showing that these metals may be preferred electron acceptors at the low H2 concentrations present in most marine sediments.

TL;DR: Knowing the processes that control the migration and transformation of chromium is important in developing and selecting effective, cost-efficient remediation designs for chromium-contaminated sites.
