Minimum biofilm inhibitory concentration (MBIC) of six sundew samples against three multi-drug-resistant E. coli strains (PBIO729, PBIO730, PBIO1986). To evaluate whether the commercial sundew biomasses and D. intermedia had the same biofilm inhibitory efficacy as the species D. rotundifolia, the MBICs of the samples D. intermedia, D. longifolia (GA), Drosera sp. (Pini), D. planta trit. (Plam) and D. longifolia (KG) were compared with the sample D. rotundifolia; a significant difference in MBIC to D. rotundifolia indicates a reduced efficacy [n = 3/E.coli sp.]; data were analyzed by Kruskal–Wallis test; ns: p ≥ 0.05, **: p ≤ 0.0021, ***: p ≤ 0.0002.
