Table 1.

Intra-biofilm properties measured to calculate the extracellular cPIA,Biofilm/c* of PIA.

PROPERTY VALUE
Cell number density (ncell) 0.19 ± 0.03 cells/μm3
Vtotala 5.26 ± 0.83 μm3
VPIAb 5.12 ± 0.83 μm3
nPIAc 1.56 ± 0.20 × 104 PIA molecules/cell
cPIA,Biofilm/c* 0.31 ± 0.07
a

Vtotal: reciprocal of cell number density

b

VPIA: average extracellular volume associated with each biofilm bacterium

c

nPIA: number of PIA molecules per biofilm bacteria
