Heavy Metal Remediation: A Sustainable Approach

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
With an emphasis on bioremediation as a crucial approach to mitigate the detrimental effects of heavy metals (HMs), this study explores the causes of HM pollution, their impact on the environment and human health, and remediation techniques. In contrast to traditional physical and chemical methods, bioremediation offers a more economical, less toxic ...

Ecology and biogeography of bacterial communities associated with chloroethene-contaminated aquifers

Frontiers in Microbiology, 2012
Massive usage, along with careless handling, storage, spills and leakages made chloroethenes (CEs) one of the most abundant classes of groundwater contaminants.

Long-Chain Fatty Acids Degradation by Desulfomonile Species and Proposal of “Candidatus Desulfomonile Palmitatoxidans”

Frontiers in Microbiology, 2020
Microbial communities with the ability to convert long-chain fatty acids (LCFA) coupled to sulfate reduction can be important in the removal of these compounds from wastewater.

Primary to post‐depositional microbial controls on the stable and clumped isotope record of shoreline sediments at Fayetteville Green Lake

Geobiology, Volume 22, Issue 4, July/August 2024.
Abstract Lacustrine carbonates are a powerful archive of paleoenvironmental information but are susceptible to post‐depositional alteration. Microbial metabolisms can drive such alteration by changing carbonate saturation in situ, thereby driving dissolution or precipitation.

Functional genomics of corrinoid starvation in the organohalide-respiring bacterium Dehalobacter restrictus strain PER-K23

Frontiers in Microbiology, 2015
De novo corrinoid biosynthesis represents one of the most complicated metabolic pathways in nature. Organohalide-respiring bacteria (OHRB) have developed different strategies to deal with their need of corrinoid, as it is an essential cofactor of ...

Microbial Autotrophy Recorded by Carbonate Dual Clumped Isotope Disequilibrium

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract The proliferation of microbial carbon fixation is a key control on the evolution of the biosphere and global carbon cycle. Most records of these metabolisms in ancient rocks come from organic matter or fossils, which are not always preserved.

Organohalide Respiration with Chlorinated Ethenes under Low pH Conditions

Environmental Science & Technology, 2017
Bioremediation at chlorinated solvent sites often leads to groundwater acidification due to electron donor fermentation and enhanced dechlorination activity. The microbial reductive dechlorination process is robust at circumneutral pH, but activity declines at groundwater pH values below 6.0.

Genomic Characteristics Distinguish Geographically Distributed Dehalococcoidia

Frontiers in Microbiology, 2020
Dehalococcoidia (Dia) class microorganisms are frequently found in various pristine and contaminated environments. Metagenome-assembled genomes (MAGs) and single-cell amplified genomes (SAGs) studies have substantially improved the understanding of Dia ...

Biodegradation of chloroethene compounds under microoxic conditions

Biotechnology and Bioengineering, Volume 121, Issue 3, Page 1036-1049, March 2024.
The authors examined the biodegradation of chloroethene compounds under microoxic conditions. The results indicated that partial reductive and cometabolic biodegradation of chloroethene compounds occurred concurrently. The findings of this study have significant implications for further research on chloroethene compound biodegradation, particularly in ...

Electrochemical applications in RAS: A review

Reviews in Aquaculture, Volume 16, Issue 1, Page 86-105, January 2024.
Abstract Electrochemical water treatment for recirculating aquaculture systems (RAS) is a promising approach for replacing the biological water treatment methods and establishing a new RAS generation with improved cost‐effectiveness, lower environmental footprint, and no start‐up periods. On top of ammonia oxidation directly into N2(g), electrochemical
