Halorespiration or dehalorespiration is the use of halogenated compounds as terminal electron acceptors in anaerobic respiration.[1] Halorespiration can play a part in microbial biodegradation. The most common substrates are chlorinated aliphatics (PCE, TCE), chlorinated phenols. Dehalorespiring bacteria are highly diverse. This trait is found in some proteobacteria, chloroflexi (green nonsulfur bacteria) and low G+C gram positive Clostridia.[2]
