Biocatalytic Reduction Reactions from a Chemist's Perspective

Angewandte Chemie International Edition, Volume 60, Issue 11, Page 5644-5665, March 8, 2021., 2021
Biocatalytic reductions: Enzymes catalyse reduction reactions with exquisite stereo‐, regio‐ and chemoselectivity, leading the way to shorter alternatives to classical synthetic routes! Abstract Reductions play a key role in organic synthesis, producing chiral products with new functionalities. Enzymes can catalyse such reactions with exquisite stereo‐,

Microbial Enzymes Used in Bioremediation

Journal of Chemistry, Volume 2021, Issue 1, 2021., 2021
Emerging pollutants in nature are linked to various acute and chronic detriments in biotic components and subsequently deteriorate the ecosystem with serious hazards. Conventional methods for removing pollutants are not efficient; instead, they end up with the formation of secondary pollutants.

Stoichiometry of the Gene Products From the Tetrachloroethene Reductive Dehalogenase Operon pceABCT

Frontiers in Microbiology, 2022
Organohalide respiration (OHR) is a bacterial anaerobic process that uses halogenated compounds, e.g., tetrachloroethene (PCE), as terminal electron acceptors.

Field Test of a Bioelectrochemical Membrane-Less Reactor for Chlorinated Aliphatic Hydrocarbon and Nitrate Removal from a Contaminated Groundwater. [PDF]

Chempluschem
This study evaluates a membrane‐less bioelectrochemical reactor in a real groundwater remediation scenario, targeting chlorinated aliphatic hydrocarbons and nitrate contamination. Electron supply via graphite granules biocathode stimulates reductive dechlorination and nitrate reduction, despite competing processes like sulfate reduction and ...

Two distinct <i>Dehalobacter</i> metagenome-assembled genomes from anaerobic chloroform and dichloromethane degrading consortia. [PDF]

Microbiol Resour Announc
ABSTRACT Here we present two metagenomes and two Dehalobacter metagenome-assembled genomes from subcultures of an anaerobic chloroform and dichloromethane degrading microbial community used for bioremediation. Our objective was to assemble and curate the genome(s) of

Direct loop mediated isothermal amplification on filters for quantification of Dehalobacter in groundwater [PDF]

Journal of Microbiological Methods, 2016
Nucleic acid amplification of biomarkers is increasingly used to monitor microbial activity and assess remedial performance in contaminated aquifers. Previous studies described the use of filtration, elution, and direct isothermal amplification (i.e. no DNA extraction and purification) as a field-able means to quantify Dehalococcoides spp.

Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

Tetrachloroethene respiration in Sulfurospirillum species is regulated by a two‐component system as unraveled by comparative genomics, transcriptomics, and regulator binding studies

MicrobiologyOpen, Volume 9, Issue 12, December 2020., 2020
Organohalide‐respiring bacteria need to sense halogenated hydrocarbons in the environment to induce the production of the enzymatic machinery required for their utilization. Identification and characterization of biological sensors for organohalides, such as the two‐component system described here, could guide synthetic approaches for monitoring ...

Microbial degradation of halogenated aromatics: molecular mechanisms and enzymatic reactions

Microbial Biotechnology, Volume 13, Issue 1, Page 67-86, January 2020., 2020
This minireview discusses the molecular mechanisms of the enzymatic reactions for degrading halogenated aromatics which naturally occur in various microorganisms. An in‐depth understanding of how microbes employ various enzymes in biodegradation can lead to the development of new biotechnologies via enzyme/cell/metabolic engineering or synthetic ...
