Increasing in situ bioremediation effectiveness through field-scale application of molecular biological tools

Frontiers in Microbiology, 2023
Leveraging the capabilities of microorganisms to reduce (degrade or transform) concentrations of pollutants in soil and groundwater can be a cost-effective, natural remedial approach to manage contaminated sites.

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, Volume 46, Issue 2, Page 44-54, Spring 2026.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Cobalamin‐Dependent Aryl Methyl Ether O‐Demethylases: Promising Enzymes for Biocatalytic Applications from Lignin Valorization to Organic Synthesis

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
Cobalamin‐dependent aryl methyl ether O‐demethylases have high potential for biocatalytic applications, including lignin valorization and synthetic chemistry. In this review, we provide a detailed overview of such O‐demethylase systems identified to date from various microorganisms, including their mechanism, substrate scope and selectivity, and ...

Effect of Sea Water Inundation on CO2 and CH4 Production of Thawing Coastal Permafrost Near Utqiaġvik, Alaska

Permafrost and Periglacial Processes, Volume 36, Issue 4, Page 787-802, October/December 2025.
ABSTRACT Rising sea levels and changing marine dynamics are increasing the inundation of previously terrestrial permafrost, accelerating thaw and altering microbial carbon cycling. On the Arctic Coastal Plain of Alaska, permafrost features like drained lake basins (DLBs) and uplands (ULs), offer distinct redox conditions and formation histories that ...

Influence of Plant Species and De‐Icing Salt on Microbial Communities in Bioretention

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Plant species shape bioretention bacterial and fungal communities and their associated functions, which drive system efficiency. These results underscore the importance of plant selection when designing bioretention systems. Moreover, the communities were preserved or recovered within 5 months after the exposure to NaCl levels typical of spring runoff.

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, Volume 72, Issue 5, Page 1593-1619, August 2025.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

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 ...

Microbiome dynamics of a polychlorobiphenyl (PCB) historically contaminated marine sediment under conditions promoting reductive dechlorination

Frontiers in Microbiology, 2016
The toxicity of polychlorinated biphenyls (PCB) can be efficiently reduced in contaminated marine sediments through the reductive dechlorination process lead by anaerobic organohalide bacteria.

Vitamin B12 as a source of variability in isotope effects for chloroform biotransformation by Dehalobacter

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
The presence of vitamin B12 has a significant effect on carbon isotope effects, consistent with an isotope masking effect. We interpret this in the context of predicted enzyme structures. Abstract Carbon and chlorine isotope effects for biotransformation of chloroform by different microbes show significant variability.

Enrichment and characterization of marine organohalide respiring bacteria and of their dehalogenating enzymes [PDF]

, 2019
Organohalide pollution of freshwater and marine sediments threatens human and environmental well-being. In freshwater and marine sediments a natural anaerobic microbiological process called reductive dehalogenation (RD) is carried out by organohalide respiring bacteria (OHRB) and reduces toxicity and improves biodegradability of organohalide pollutants.
