Halogenation and Dehalogenation Potential of Microorganisms in Yangtze River Waters [PDF]

Microorganisms
The discharge of pollutants into rivers has been increasing with the rapid industrial development and extensive agricultural use of pesticides and herbicides. Halogenated organic compounds (HOCs) represent a significant class of environmental pollutants.

Microbially-mediated halogenation and dehalogenation cycling of organohalides in the ocean [PDF]

Nature Communications
Microbially mediated organohalide cycling in the ocean has profound implications for global biogeochemical cycles and climate, but the geographic distribution and diversity of the halogenation-dehalogenation cycling microorganisms remain unknown.

Synthesis and biological evaluation of novel N-α-haloacylated homoserine lactones as quorum sensing modulators [PDF]

Beilstein Journal of Organic Chemistry, 2014
Novel N-α-haloacylated homoserine lactones, in which a halogen atom was introduced at the α-position of the carbonyl function of the N-acyl chain, have been studied as quorum sensing (QS) modulators and compared with a library of natural N-acylated ...

Aerobic oxidative bromination and iodination enabled by alloxan and ascorbic acid to mimic flavin-dependent halogenases [PDF]

Nature Communications
The fundamentally significant halogenation processes in organic synthesis heavily depend on the use of hazardous and toxic elemental halogens directly or indirectly, inevitably increasing environmental burden and leading to various production problems ...
