Table 2 CPS content (μg/ml) following treatment of K. pneumoniae biofilm of different days with phage/bacterial depolymerase (20 units/ml each)

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

Biofilm age CPS content (μg/ml)
Days Untreated Phage enzyme treated* Bacterial enzyme treated#
1 0.989 ± 0.15 0.639 ± 0.22 0.279 ± 0.18
3 1.082 ± 0.24 0.846 ± 0.36 0.357 ± 0.17
5 1.589 ± 0.09 0.978 ± 0.24 0.511 ± 0.15

  1. Data is presented as mean ± SD (n = 3). [*p > 0.05 (average CPS content in phage depolymerase treated vs untreated biofilm), # p < 0.05 (average CPS content in bacterial depolymerase treated vs untreated biofilm)]. Denatured bacterial/phage depolymerase heated at 75 °C for 10 min were used as controls for biofilm treatment. But no effect on CPS content was observed
