Vanadium in the Environment: Biogeochemistry and Bioremediation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(39), P. 14770 - 14786

Published: Sept. 11, 2023

Vanadium(V) is a highly toxic multivalent, redox-sensitive element. It widely distributed in the environment and employed various industrial applications. Interactions between V (micro)organisms have recently garnered considerable attention. This Review discusses biogeochemical cycling of its corresponding bioremediation strategies. Anthropogenic activities resulted elevated environmental concentrations compared to natural emissions. The global distributions atmosphere, soils, water bodies, sediments are outlined here, with notable prevalence Europe. Soluble V(V) predominantly exists exhibits high mobility chemical reactivity. transport within media across food chains also discussed. Microbially mediated transformation evaluated shed light on primary mechanisms underlying microbial reduction, namely electron transfer enzymatic catalysis. Additionally, this highlights strategies by exploring their geochemical influences technical implementation methods. identified knowledge gaps include particulate speciation associated behaviors as well processes marine environments. Finally, challenges for future research reported, including screening hyperaccumulators V(V)-reducing microbes field tests approaches.

Vanadate Bio-Detoxification Driven by Pyrrhotite with Secondary Mineral Formation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(4), P. 1807 - 1818

Published: Jan. 4, 2023

Vanadium(V) is a redox-sensitive heavy-metal contaminant whose environmental mobility strongly influenced by pyrrhotite, widely distributed iron sulfide mineral. However, relatively little known about microbially mediated vanadate [V(V)] reduction characteristics driven pyrrhotite and concomitant mineral dynamics in this process. This study demonstrated efficient V(V) bioreduction during 210 d of operation, with lifespan 10 times longer than abiotic control, especially stable period when the removal efficiency reached 44.1 ± 13.8%. Pyrrhotite oxidation coupled to could be achieved an enriched single autotroph (e.g., Thiobacillus Thermomonas) independently. Autotrophs Sulfurifustis) gained energy from synthesize organic intermediates, which were utilized heterotrophic reducing bacteria such as Anaerolinea, Bacillus, Pseudomonas sustain reduction. was reduced insoluble tetravalent V, while mainly produced Fe(III) SO42–.

Elucidating Multiple Electron-Transfer Pathways for Metavanadate Bioreduction by Actinomycetic Streptomyces microflavus

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(48), P. 19921 - 19931

Published: Nov. 7, 2023

While microbial reduction has gained widespread recognition for efficiently remediating environments polluted by toxic metavanadate [V(V)], the pool of identified V(V)-reducing strains remains rather limited, with vast majority belonging to bacteria and fungi. This study is among first confirm V(V) capability Streptomyces microflavus, a representative member ubiquitous actinomycetes in environment. A removal efficiency 91.0 ± 4.35% was achieved during 12 days operation, maximum specific growth rate 0.073 d–1. bioreduced insoluble V(IV) precipitates. took place both intracellularly extracellularly. Electron transfer enhanced bioreduction increased electron transporters. The electron-transfer pathways were revealed through transcriptomic, proteomic, metabolomic analyses.

Deciphering Vanadium Speciation in Smelting Ash and Adaptive Responses of Soil Microorganisms

ACS Nano, Journal Year: 2024, Volume and Issue: 18(3), P. 2464 - 2474

Published: Jan. 10, 2024

Abundant smelting ash is discharged during pyrometallurgical vanadium (V) production. However, its associated V speciation and resultant ecological impact have remained elusive. In this study, in influence on the metabolism of soil microorganisms were investigated. Smelting ashes from smelters contained abundant (19.6-115.9 mg/g). V(V) was dominant species for soluble V, while solid primarily existed bioavailable forms. Previously unrevealed nanoparticles (V-NPs) prevalently detected, with a peak concentration 1.3 × 10
