Carbon isotope fractionation during aerobic biodegradation of trichloroethene by Burkholderia cepacia G4: a tool to map degradation mechanisms [PDF]

, 2002
The strain Burkholderia cepacia G4 aerobically mineralized trichloroethene (TCE) to CO2 over a time period of similar to20 h. Three biodegradation experiments were conducted with different bacterial optical densities at 540 nm (OD(540)s) in order to test

Purification and Characterization of Hydrolytic Haloalkane Dehalogenase from Xanthobacter autotrophicus GJ10 [PDF]

, 1985
A new enzyme, haloalkane dehalogenase, was isolated from the 1,2-dichloroethane-utilizing bacterium Xanthobacter autotrophicus GJ10. The purified enzyme catalyzed the hydrolytic dehalogenation of n-halogenated C1 to C4 alkanes, including chlorinated ...

Supramolecular Gels as Active Tools for Reaction Engineering

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Batteries From Reused, Recycled, and Surplus Materials

Advanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...
