Detached = cells washed off by rinsing; attached = cells remaining on
the membrane after rinsing and detatched from the membrane after
sonication; total = the sum of detached and attached. The mean value,
standard deviation (SD) and standard error of the mean results (SEM) are
expressed as Log(CFU/mL) of N=18.
Characterization of biofilms grown under ALI and LLI
Resistance to physical disruption, such as mechanical or hydrodynamic
shear strength, is one of the most critical characteristics to be
considered when investigating biofilm eradication strategies. In this
study, the differences between the biofilms formed on different
interfaces (ALI and LLI) was compared by assessing the CFU number of
detached, attached and total biofilm collected from eighteen replicates.
Fig. 3 shows the total CFU (left) and the ratio of the attached to the
total (right) is compared.
