The images presented above show that on the one hand
adsorbates of D. vulgaris-EPS on metal surfaces decrease the
extent of adhesion of D. vulgaris cells. On the other hand,
inhomogeneous are formed and no long-term stable protective
coating is established yet. From the FM-images, only a small
influence of the adsorption temperature can be derived.
The FM images presented above only reflect the adsorbed
carbohydrate fraction of the EPS to which ConA-FITC binds.
