Results of bacterial growth inhibition by agar diffusion method with 12 mm diameter pieces of film reflecting 12 different combinations of three agents (as shown as 12 sets in Table 2) incubated at 37 °C, 48 h. Arrows indicate areas of detectable antimicrobial activity with C as control shown in inset around which no inhibition zone was observed as it is starch-glycerol film without incorporation of any antimicrobial agents
