Microbial cells flocculation efficiency as function of MWNTs concentration. Flocculation of E. coli (A,E), S. enterica T. (B,F), E. faecalis (C,G) and S. cerevisiae (D,H) was measured after 2 hours (A–D) and 18 hours (E–H). In all the panels: black and green lines, flocculation induced by sample “c” in the absence and the presence of NaCl, respectively; red and blue lines, flocculation induced by sample “e” in the absence and the presence of NaCl, respectively.
