Influence of sequential application of biocontrol agent and pathogen on interaction and biocontrol effect. Cell number of strains P3 and S1 in mono-species biofilms and in dual-species biofilms are indicated. Results (in CFU/cm2) of the six technical replicates (dots) and their average (columns) are shown per strain and in total (grey) for the dual-species biofilms after 44 h of incubation, whereby S1 was only applied during the last 22 h. The actual inoculum density (CFU/ml) applied in every biofilm experiment is indicated with a horizontal line in the colour corresponding to the used strain. The total amount of cells expected for cooperation in dual-species biofilms is indicated as a yellow horizontal line. Also biodiversity, selection and complementarity effect, calculated based on the last 22 h of incubation i.e. when both strains were present, are shown
