Biokatalytische Reduktionen aus der Sicht eines Chemikers

Angewandte Chemie, Volume 133, Issue 11, Page 5706-5727, March 8, 2021., 2021
Biokatalytische Reduktionen: Enzyme katalysieren Reaktionen mit ausgezeichneter Stereo‐, Regio‐ und Chemoselektivität, was den Weg zu kürzeren Alternativrouten eröffnet. Abstract Reduktionsreaktionen spielen eine zentrale Rolle in der organischen Chemie zur Synthese chiraler Produkte. Insbesondere Enzyme katalysieren solche Reaktionen in hoher Stereo‐,

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.

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.

Trichloromethane dechlorination by a novel Dehalobacter sp. strain 8M reveals a third contrasting C and Cl isotope fractionation pattern within this genus [PDF]

, 2022
Trichloromethane (TCM) is a pollutant frequently detected in contaminated aquifers, and only four bacterial strains are known to respire it. Here, we obtained a novel Dehalobacter strain capable of transforming TCM to dichloromethane, which was ...

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 ...

Growth of Dehalobacter and Dehalococcoides spp. during Degradation of Chlorinated Ethanes [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Mixed anaerobic microbial subcultures enriched from a multilayered aquifer at a former chlorinated solvent disposal facility in West Louisiana were examined to determine the organism(s) involved in the dechlorination of the toxic compounds 1,2-dichloroethane (1,2-DCA) and 1,1,2-trichloroethane (1,1,2-TCA) to ethene ...

Ecogenomics of microbial communities in bioremediation of chlorinated contaminated sites

Frontiers in Microbiology, 2012
Organohalide compounds such as chloroethenes, chloroethanes and polychlorinated benzenes are among the most significant pollutants in the world. These compounds are often found in contamination plumes with other pollutants such as solvents, pesticides ...

A Role for Dehalobacter spp. in the Reductive Dehalogenation of Dichlorobenzenes and Monochlorobenzene

, 2016
Previously, we demonstrated the reductive dehalogenation of dichlorobenzene (DCB) isomers to monochlorobenzene (MCB), and MCB to benzene in sediment microcosms derived from a chlorobenzene-contaminated site.
