Abstract

© Springer-Verlag Berlin Heidelberg 2016. Organohalide-respiring bacteria harness energy using halogenated organic compounds as electron acceptors. The objective of this chapter is to evaluate the thermodynamics and energetics of organohalide respiration, that is, (i) how much energy the organisms can obtain from dehalogenation, and how this energy compares to the energy available from other electron acceptors; (ii) how much energy the organisms actually harness from the dehalogenation reactions; and (iii) how much energy the organisms not only forfeit but actually dissipate when they convert halogenated compounds co-metabolically rather than metabolically. Alternative fates of organohalides-their anaerobic oxidation and fermentation- are also discussed.
