Article Title: Physical mechanisms driving the reversible aggregation of Staphylococcus aureus and response to antimicrobials

doi: 10.1038/s41598-021-94457-1

Figure Lengend Snippet: Cellular aggregation is reversible and specific to bacteria with a lower cell potential. ( a ) Reversibility of S. aureus aggregation in water with 0.015% and 0.5% NaCl and in Nutrient broth. ( b ) Aggregation behavior of E. hirae and P. aeruginosa in water with 0.015% and 0.5% NaCl and in Nutrient broth as a function of pH. Each scale bar is 4 µm. Surface potential of P. aeruginosa and E. hirae suspended in water with 0.015% and 0.5% NaCl. The dotted lines are to provide visual guidance. E. hirae aggregate at low pH (lower cell potential) while P. aeruginosa does not.
