title: Versatility and application of anaerobic ammonium-oxidizing bacteria.
abstract: With the unique cell compartmentalization and the ability to simultaneously oxidize ammonium and reduce nitrite into nitrogen gas, anaerobic ammonium-oxidizing (anammox) bacteria have challenged our recognitions of microorganism. The research conducted on these bacteria has been extended from bench-scale tryouts to full-scale reactor systems. This review addresses the recently discovered versatile properties of anammox bacteria and the applications and obstacles of implementing the anammox process in ammonia-rich wastewater treatment. We also discuss the merits and drawbacks of traditional and anammox-based processes for nitrogen removal and suggest areas for improvement.
