Abstract: Halogenated compounds are ubiquitous in the environment. This work examines the potential of Bradyrhizobium japonicum 273 strain for degrading 1,2-dibromoethane. This study compares biodegradation with free and immobilized cells onto a granular polymeric support. Processes of dehalogenation were carried out with different initial substrate concentrations in shaken flasks and in a laboratory bioreactor in presence and absence of constant electric field. There was significant positive effect of electric field on the biodegradation rate. Complete mineralization was verified by measuring stoichiometric release of the biodegradation products.
