Growth curves of E. coli ESBL37B15_13_1E in the presence of different BAC-C12 (a–c) and DADMAC-C10 (d–f) concentrations without clay mineral addition (a, d) and in the presence of smectite (b, e) and kaolinite (c, f). Visible are growth curves at QAAC concentrations that were inhibitory in the absence of clay minerals and the presence of kaolinite while growth was not inhibited in the presence of smectite.
