The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants

open access: yesMicrobial Biotechnology, Volume 19, Issue 5, May 2026.
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Substitution of cysteine for a conserved alanine residue in the catalytic center of type II iodothyronine deiodinase alters interaction with reducing cofactor [PDF]

open access: yes, 2002
Human type II iodothyronine deiodinase (D2) catalyzes the activation of T(4) to T(3). The D2 enzyme, like the type I (D1) and type III (D3) deiodinases, contains a selenocysteine (SeC) residue (residue 133 in D2) in the highly conserved

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

open access: yes, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Multiple Dual C−Cl Isotope Patterns Associated with Reductive Dechlorination of Tetrachloroethene [PDF]

open access: yes, 2017
Dual isotope slopes are increasingly used to identify transformation pathways of contaminants. We investigated if reductive dechlorination of tetrachloroethene (PCE) by consortia containing bacteria with different reductive dehalogenases (rdhA) genes can

Copper increases reductive dehalogenation of haloacetamides by zero-valent iron in drinking water: Reduction efficiency and integrated toxicity risk.

open access: yesWater Research, 2016
The haloacetamides (HAcAms), an emerging class of nitrogen-containing disinfection byproducts (N-DBPs), are highly cytotoxic and genotoxic, and typically occur in treated drinking waters at low μg/L concentrations.
