Xylella fastidiosa Differentially Accumulates Mineral Elements in Biofilm and Planktonic Cells
Figure 7
Mn addition to PD2 affects biofilm formation and cell-to-cell interactions.
Cells grown in PD2 (n = 3) were compared to cells grown in 0.25 mM MnCl2 (n = 3) or 2.5 mM MnCl2 (n = 3). The planktonic cells (A, C, E) were separated from biofilm (B, D, F) and measured by ICP-OES for manganese content (log 10 scale)(A, B), total optical density as a measure of cells in different states (C, D) and settling rate as a measure of cell-to-cell aggregation (E, F). Data presented as mean and standard error of the mean.
