Diameters of inhibition zones (mm) in the antibacterial tests of AgNPs/PPE, PPE, kanamycin, and AgNO₃ against four bacterial strains.

Bacteria	Kanamycin (+)	PPE (−)	AgNO3	AgNPs/PPE
Salmonella typhi	17.5 ± 1.5	10.4 ± 0.2	13.0 ± 1.9	13.9 ± 0.2
Staphylococcus aureus	17.4 ± 1.2	8.9 ± 0.1	12.4 ± 1.9	11.6 ± 1.1
Bacillus subtilis	13.8 ± 1.5	8.5 ± 0.2	11.5 ± 0.7	11.5 ± 0.5
Streptococcus pyogenes	17.7 ± 4.2	8.3 ± 0.1	10.8 ± 0.8	11.2 ± 1.5

The results are expressed as mean ± SD (n = 3). The means in a row with different letters , or are significantly different ().
