 ated pollutants are usually employed in industrial procedures and can be a
 n environmental concern when they are accidentally spilled to the natural 
 medium and reach groundwater sources. The usual low oxygen concentration i
 n these areas allows to perform an anaerobic bioremediation by employing o
 rganohalide-respiring bacteria. One of the bottlenecks for their applicati
 on is the hydrogen bioavailability in the aquifers\, required as electron 
 donor during the biological reduction of the pollutants. This issue can be
  solved by using bioelectrochemical systems\, which can provide electrons 
 to the organohalide-respiring bacteria or directly to the contaminants.\n\
 nIn this study\, we successfully performed the abiotic electrochemical deg
 radation of the brominated compounds dibromomethane and 1\,2-dibromoethane
 \, and the biologically-mediated degradation of the chlorinated pollutants
  1\,2-dichloropropane and chloroform. In these degradations\, previously e
 nriched anaerobic consortia belonging to the genera Dehalogenimonas\, Deha
 lobacter and Dehalobacterium were employed and completely dehalogenated pr
 oducts were obtained at the end of the operation. The effect of the cathod
 ic potential in the degradation rate and in the coulombic efficiency of th
 e processes was assessed for the degradation of each contaminant. The resu
 lts obtained show that bioelectrochemical systems are a promising technolo
 gy in order to work with organohalide-respiring bacteria in the degradatio
 n of organohalide pollutants.\n\n \n\nI partecipanti registrati ricevera
