Jul 1, 2004 · We have developed simple methods for MIC determination for four vanadium salts, which are specific to each salt due to varying influences on pH of media. Whole bacterial cell bioluminescence reduction toxicity tests were conducted with all four vanadium salts and these give comparable results to MIC tests.

Mar 26, 2014 · To explore the potential of archaea in vanadium reduction, we studied microbial reduction of vanadate (V 5 +) by a mesophilic (Methanosarcina mazei with the optimal temperature of 37 °C) and a thermophilic (Methanothermobacter thermautotrophicus, with the optimum temperature of 65 °C) methanogen in both growth and non-growth media.

Jan 16, 2025 · Microbial vanadate (V(V)) reduction is a key process for environmental geochemistry and detoxification of vanadium (V). However, the electron transfer pathways and V isotope fractionation involved in this process are not yet fully understood.

May 1, 2004 · These studies demonstrate that G. metallireducens can grow via vanadium (V) respiration and that stimulating the activity of Geobacteraceae, and hence vanadium (V) reduction, can be an effective strategy for in situ immobilization of vanadium in contaminated subsurface environments.

Apr 1, 2021 · Our results demonstrate the potential to use microorganisms to conduct elemental mining and other bioindustrial processes in space locations with non-1 × g gravity. These same principles apply to extraterrestrial bioremediation and elemental recycling beyond Earth.

Mar 5, 2019 · To date, bioremediation of vanadium-contaminated environments by indigenous microorganisms has rarely been evaluated. This paper reports a systematic investigation into vanadium distributions and microbial communities in …

Investigations into bacterial responses to vanadium are rare, and in this study were initiated by isolating cultures from crude oil contaminated soil from Russia and Saudi Arabia. Addition of vanadyl sulphate and vanadium pentoxide created acid

Vanadium is considered essential for microorganisms and mammals in trace amounts. 1 Laboratory 2 and epidemiological 1 evidence suggest that vanadium may play a beneficial role in the prevention of heart disease.

Apr 6, 2024 · Commonly reduction of vanadium (V) to vanadium (IV) is recognized as a feasible method to detoxify them in groundwater as the vanadium (IV) had less toxic and mobile 23.

Sep 1, 2015 · Vanadium (V) is effectively reduced by immobilized mixed anaerobic sludge. V (IV) is the main reduction product and it precipitates instantly from groundwater. Initial V (V), COD concentrations, pH and conductivity affect the performance. High-throughput pyrosequencing analysis indicates the decreased diversity.
