Thickness and Surface Density of Extracellular Polymer on Acidithiobacillus ferrooxidans
Applied and Environmental Microbiology
In vivo force microscopy measurements of Acidithiobacillus ferrooxidans revealed a repulsive force that was due to the presence of extracellular polymers on the bacterium's surface. Measured force-distance profiles were fit to steric force theory to estimate the density and thickness values of these exopolymers. The polymer densities were 3.4 × 1016 to 7.1 × 1016 molecules m−2, and the equilibrium thickness was 29 nm.
