Fig. 3From: Reversible bacterial immobilization based on the salt-dependent adhesion of the bacterionanofiber protein AtaADetachment of ADP1 (pAtaA) cells immobilized on PS and glass surfaces. The cells retained on the surfaces after being washed with 100 mM KCl solution or dH2O were visualized and quantified by crystal violet staining. Photographs indicate the stained cells retained on the surface. Data are expressed as mean ± SEM (n = 3)Back to article page
