Purpose The compounds 1-octyne and 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide (PTIO) are frequently used as nitrification inhibitors for ammonia-oxidizing bacteria (AOB) and archaea (AOA), respectively, but their influence on comammox Nitrospira remains unclear. In this study, we examine...
