Along the Randers Fjord estuary (Denmark), gradients of salinity, nutrients, and organic loading can be observed, and anammox has been detected previously at some sites. The aim of this study was to correlate the activity, abundance, and diversity of anammox bacteria, AOB and AOA in surface sediment along the fjord with the sediment microdistribution of nitrite. Using 15 N incubations, 16S rRNA gene sequencing, and fluorescence in situ hybridization, anammox was only detected at the two innermost stations where it accounted for 5-16% of the total N 2 production and 0.1-0.25% of the total prokaryotic population. These numbers result in cell-specific anammox rates of about 6 fmol N day-1, comparable to literature values.
