Table 1 Penetration of gentamicin (10 μg/ml) through biofilm of K. pneumoniae B5055

From: Aeromonas punctata derived depolymerase improves susceptibility of Klebsiella pneumoniae biofilm to gentamicin

Biofilm age (Days) Inhibition zones (mm) observed following penetration of gentamicin through disc placed on % Retardation
Membrane with no biofilm Membrane with colony biofilm

  1. The zone of growth inhibition observed on plates with discs having no biofilms was taken as 100 % penetration and used to determine the percentage retardation of gentamicin through biofilms. Data is presented as mean ± SD. The experiment was performed thrice in triplicates
