Figure 3.
Mean cross-sectional area of PCaAP aggregates for control test (without P. mirabilis and without LPS) compared with mean cross-sectional area of PCaAP aggregates in the presence of (a,b) P. mirabilis and freely suspended LPS of different concentrations given in the insets and (c) LPS coated on polystyrene latex beads. In the case of P. mirabilis the value of mean cross-sectional area of PCaAP aggregates for pH = 7.5 is not given because for this pH, the agglomerations of bacteria are difficult to distinguish from PCaAP aggregates.
