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.
