A comparison between the elemental surface compositions and electrokinetic properties of oral streptococci with and without adsorbed salivary constituents.


In order to characterize the functional cell surface, isoelectric points and elemental surface concentration, the ratios of nitrogen, oxygen and phosphorus to carbon of saliva-coated strains were determined by pH-dependent zeta potential measurements and X-ray photoelectron spectroscopy and compared with those of uncoated strains. The measurements of… (More)
