a
Percentage of glass surface covered by bacteria after static adhesion step and 15 min of medium flow.
b
Biofilms were grown under a flow of PPGAS medium.
c
Standard deviations were <10% for all values, except for the average thickness of the PAOU(pMMB207-PA2663) biofilm, which was 1.44 ± 0.47 μm. ND, not determined.
