| Abstract: | The local surface properties of polystyrene (PS) dishes incubated for 14 h with gram‐negative cells (Shewanella putrefaciens) were investigated by atomic force microscopy (AFM) in aqueous solutions at two pH values (4 and 10). The AFM images and force curves revealed the presence of a polymeric layer adsorbed onto the PS surfaces in acid media. In contrast, no evolution was observed in the case of basic media.
