Genetic Analysis of Citrobacter sp.86 Reveals Involvement of Corrinoids in Chlordecone and Lindane Biotransformations

Frontiers in Microbiology, 2020
Chlordecone (Kepone®) and γ-hexachlorocyclohexane (γ-HCH or lindane) have been used for decades in the French West Indies (FWI) resulting in long-term soil and water pollution. In a previous work, we have identified a new Citrobacter species (sp.86) that

Evaluation of the biological treatment of a real contaminated groundwater through reductive dechlorination biostimulation

Frontiers in Chemical Engineering
Chlorinated aliphatic hydrocarbons (CAHs) are common groundwater contaminants due to improper utilization in past industrial activity. Anaerobic reductive dechlorination, where bacteria use CAHs as electron acceptors, is crucial for bioremediation ...

Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).

Dimensionality‐Driven Carbon Reconstruction Activates MXene Quantum Dots for Dechlorination

Small, EarlyView.
Finite Ti2CO2${\rm Ti}_2{\rm CO}_2$ MXene quantum dots exhibit a reconstruction‐induced activation mechanism absent in extended two‐dimensional MXenes. Carbon‐sublattice reconstruction generates electronically active motifs that facilitate charge redistribution and promote dechlorination of chlorinated hydrocarbons, revealing a new route for activating
