Complete Genome Sequence of the Anaerobic Perchlorate-Reducing Bacterium Azospira suillum Strain PS

Azospira suillum strain PS (formally Dechlorosoma suillum strain PS) is a metabolically versatile betaproteobacterium first identified for its ability to grow by dissimilatory reduction of perchlorate and chlorate [denoted (per)chlorate]. Together with Dechloromonas species, these two genera represent the dominant (per)chlorate-reducing bacteria in mesophilic freshwater environments. In addition to (per)chlorate reduction, A. suillum is capable of the anaerobic oxidation of humic substances and is the first anaerobic nitrate-dependent Fe(II) oxidizer outside the Diaphorobacter and Acidovorax genera for which there is a completed genome sequence.
