Agar diffusion zone of the examined NGs against pathogens S. aureus and E. coli O157:H7.

Samples	S. aureus (in mm)	E coli O157:H7 (in mm)
NGCT	11.0 ± 0.1 A	9.0 ± 0.1 a
NGCV	15.0 ± 0.2 B	12.0 ± 0.1 b
NGCTCV25:75	16.5 ± 0.1 C	12.3 ± 0.1 c
NGCTCV50:50	20.1 ± 0.1 D	15.0 ± 0.1 d
NGCTCV75:25	18.3 ± 0.1 C	12.05 ± 0.1 c

The zones of inhibition were determined using the well diffusion method, and each value represents the average of three replicates (see Figure S1). ^A,B,C,D Means within a column for Staphylococcus aureus, followed by the same letter (A–D), are not significantly different at the p < 0.05 level, according to the pairwise comparison of treatments (see Table S3). ^a,b,c,d Means within a column for Escherichia coli, followed by the same letter (a–d), are not significantly different at the p < 0.05 level, according to the pairwise comparison of treatments (see Table S4).
