Nanotechnology for site remediation: dehalogenation
of organic pollutants in soils and groundwater by nanoscale iron particles, in 6th International Congress on Environmental Geotechnics, 30 Sep 2009, New Delhi, India.
Notably, while healthy controls did not display any significant variations in microbiotic signatures, NCGS patients displayed significant changes in bacteria responsible for dehalogenation
, ammonia oxidation, xylan and cellulose degradation, sulfate reduction, and nitrogen fixation especially while adhering to GFD.
removes halides from organic compounds resulting in lower halogenated or nonhalogenated products and is important in bioremediation.
Biochemists and biologists from around the world offer 35 articles in various areas of biochemistry, such as protein misfolding diseases, amyloid proteins at the molecular level, the mechanisms and functions of spatial protein quality control, regulated protein degradation and the ubiquitin system and autophagy, ubiquitin ligases, mechanisms of deubiquitinase specificity and regulation, proteasomal and autophagic degradation systems, mechanisms of autophagy initiation, the systems biology of metabolism, metabolite measurement, isocitrate dehydrogenase and cancer therapeutics, tools for patchy switching in biology, the biochemistry of reductive dehalogenation
, electric fields and enzyme catalysis, the eukaryotic DNA replication fork, and the telomerase mechanism of telomere synthesis.
of halogenated organic compounds: Novel strategies for bioremediation of contaminated sediments of contaminated sediments of contaminated sediments of contaminated sediments.
The primary process of both mechanisms is similar dehalogenation
leading to so-called surface-stabilized radicals (SSR), and the subsequently formed dangling bonds of the dehalogenated carbons bind to the underlying metal surface.
For all catalysts, other side-reactions as dehalogenation
, deamination, and/or hydroxylation were not detected.
Wubet et al., "Genome sequences of two dehalogenation
specialists--Dehalococcoides mccartyi strains BTF08 and DCMB5 enriched from the highly polluted Bitterfeld region," FEMS Microbiology Letters, vol.
Glutathione is the reducing agent for the reductive dehalogenation
of tetrachloro-p-hydroquinone by extracts from a Flavobacterium sp.
These radicals attack indiscriminately all species present in the reaction, oxidizing organic compounds by abstraction of hydrogen or engaging in double bonds and aromatic rings (hydroxylation), causing reactions such as demethoxylation, dehalogenation
, dealkylation, denitration, deamination and decarboxylation [5, 6].
Various authors have reported HPTC and related chlorinated pesticides degradation by dehydrohalogenation and dehalogenation
mechanism [23 31].
