Lecithin vesicles containing different cations were prepared by sonication and characterized. When the concentration of the divalent cations in the buffer was increased from 1 mM to about 100 mM the cation-concentration inside of the vesicles did not increase proportional to the outside concentration, but showed a saturation behaviour. The efflux of various(More)
Continuous cultivation of Pelobacter acidigallici on gallic acid is accompanied by biofilm formation. Steady states can be obtained at dilution rates nearly twice the maximum growth rate. A two-compartment model is presented which allows us to determine rate constants of attachment and detachment. The model is based on the assumption that the biofilm is(More)

In continuation of earlier work, the steady-state fluorescence polarization in a globally oriented system of planar lipid membranes was analyzed experimentally and theoretically for the fluorophores 8-anilino-1-naphthalenesulfonate, 1,6-diphenyl-1,3, 5-hexatriene, dansyllysine-valinomycin and n-(9-anthroyloxy) fatty acids. The theoretical analyses of(More)
