EUBI‐II‐III (Eubacteria), ALF968 (Alphaproteobacteria), BET42a (Betaproteobacteria), R‐BT065 (R‐BT cluster of Betaproteobacteria), CF319a (Bacteroidetes), and AcI‐852 (AcI lineage of Actinobacteria). The mean relative abundance of probe‐specific hybridized cells (n = 9) is given as % of DAPI counts ± SD.
