Fig. 4

Resazurin metabolization curves for E. coli (a), E. faecalis (b), and WWTP effluent (c) incubated with various membranes on PP, VS and MFRF supporting layers. Terms “Bacteria alone” and “WWTP effl. alone” mean pure inoculum incubated without a membrane. Values represent the mean ± SD of triplicate determinations. This figure shows a set of results of one experimental run as an example of three analogous independent experiments for either E. coli, E. faecalis or WWTP effluent
