Table 2.
Two-way factorial ANOVA results of the duospecies experiment using P. aeruginosa and E. coli. Bacterial cell density (log cells cm−2 membrane) was selected as dependent variable and membrane type (PSF, PVDF, and PS) and bacterial coexistence (mono versus duospecies) as predictor variables.
