  • a Ammonia-oxidizing bacterium (AOB) or nitrite-oxidizing bacterium (NOB).

  • b Data indicate whether the species genome contains a putative AHL synthase (LuxI homolog) and a putative AHL receptor (LuxR homolog) and if AHLs were detected in pure cultures by a bioassay, respectively. For example, +/+ indicates that the genome contains QS genes and that AHLs were detected.
