Evaluation of Gellan Gum Film Containing Virgin Coconut Oil for Transparent Dressing Materials

Table 3

Disc diffusion test results of gellan-norfloxacin (GG-NF), gellan gum (GG), and gellan gum containing different concentrations of virgin coconut oil composite films (GG-VCO1, GG-VCO3, and GG-VCO5) against the four tested bacteria as indicated by the zone of inhibition (mm).

Bacteria species	Zone of inhibition (mm)^1,2
