Isolation, cultivation, and characterization of ammonia-oxidizing bacteria and archaea adapted to low ammonium concentrations [PDF]
, 2011 Ammonia-oxidizing microorganisms (AOM) generate their energy by the oxidation of ammonia (NH3) to nitrite (NO2−). This process can be carried out by ammonia-oxidizing bacteria (AOB) as well as by the recently discovered ammonia-oxidizing archaea (AOA ...

Ammonia‐oxidizing archaea: important players in paddy rhizosphere soil? [PDF]
Environmental Microbiology, 2008 Summary The diversity (richness and community composition) of ammonia‐oxidizing archaea (AOA) and bacteria (AOB) in paddy soil with different nitrogen (N) fertilizer amendments for 5 weeks were investigated using quantitative real‐time polymerase chain reaction, denaturing gradient gel electrophoresis (DGGE) jand ...

Ecophysiological Characterization of Ammonia-Oxidizing Archaea and Bacteria from Freshwater [PDF]
Applied and Environmental Microbiology, 2012 ABSTRACT Aerobic biological ammonia oxidation is carried out by two groups of microorganisms, ammonia-oxidizing bacteria (AOB) and the recently discovered ammonia-oxidizing archaea (AOA). Here we present a study using cultivation-based methods to investigate the differences in growth of three AOA cultures and one AOB culture ...
