Representative force-distance curves. (A) Representative force-piezo displacement measured on mica (black) and on top of single bacteria grown in MH2 (dark green) and in MB (red), obtained in seawater. Loading force-indentation depth (blue) curves resulted from subtracting black curve from the green (B) and the red ones (C) at constant loading force. Curves (B) and (C) were fitted according Hertz’s model (green) and linear model (magenta) to calculate elasticity modulus and kB, respectively.
