Taxa of particular interest and their detection, type of colony morphology, and range of relative abundance observed during the experiment

Taxon	Detection methoda	Colony type	Relative abundanced (%)	Permanent presenceh
Vibrio sp.	PAb, Colc	II, III, XVI	5–60e	+
Pseudomonas sp. strain MWH1	PAb	IV	<0.1–80e	+g

^aPAb, polyclonal antibody; MAb, monoclonal antibody; Col, detection and enumeration by the plating approach. 

^bTaxonomically heterogeneous. 

^cFor comparison of the two methods, see Fig. 4. 

^dRange observed for both reactors throughout the experiment. 

^ePercentage of total cell numbers. 

^fPercentage of total CFU. 

^gDue to cross-reactivity of PAb not being ensured. 

^h+, detected in all investigated samples; −, not detected in all of the investigated samples.
