Brominated organic compounds such as 1,2-dibromoethane (1,2-DBA) are highly toxic groundwater contaminants. Multi-element compound-specific isotope analysis bears the potential to elucidate the biodegradation pathways of 1,2-DBA in the environment, which is crucial information to assess its fate in contaminated sites.

Chlorinated ethanes are frequent groundwater contaminants but compound specific isotope analysis (CSIA) has been scarcely applied to investigate their degradation pathways. In this study, dual carbon and chlorine isotope fractionation was used to investigate for the first time the anoxic biodegradation of 1,1,2-trichloroethane (1,1,2-TCA) using a Dehalogenimonas-containing culture.

Anaerobic microbial transformation of chlorinated alkanes in cultures derived from Besòs River estuary sediments / Mortan, Siti Hatijah ; Marco Urrea, Ernest, dir. (Universitat Autònoma de Barcelona.

Els compostos orgànics halogenats (organohalogenats) són recalcitrants i presenten efectes tòxics per la salut humana i l'ecosistema. A partir d'uns sediments de la desembocadura del riu Besòs (Barcelona, Espanya) es va establir un cultiu anaerobi estable i no metanogènic que exclusivament dehalogenava cloro- i bromoalcans que tenen els àtoms d'halògens en carbonis adjacents via dihaloeliminació.
