The ζ-potential of the S-layer containing strains harvested in the late-stationary and exponential growth phases. The bacteria are suspended in a 10-mM KH2PO4 buffer. Late-stationary phase (unfilled symbols); logarithmic phase (solid symbols). L. crispatus DSM20584 (triangles); L. helveticus ATCC12046 (circles); and L. helveticus ATCC15009 (diamonds). Error bars are shown, but are generally smaller than the symbols for bacteria harvested in late-stationary phase.
