Table 3 Bacterial growth inhibition diameter (cm) caused by varying EPS concentrations

EPS concentration
Strains	Ampicillin	10 mg/mL	20 mg/mL	30 mg/mL
Klebsiella pneumoniae ATCC 13884	0.5 ± 0.06^a	0^b	0^b	0^b
Pseudomonas aeruginosa ATCC 10145	0.23 ± 0.06^a	0^b	0^b	0^b
Staphylococcus aureus ATCC 6538	1.53 ± 0.06^a	0.47 ± 0.06^b	0.31 ± 0.03^b	0.37 ± 0.06^b
Nocardia brasiliensis ATCC 19296	0.93 ± 0.08 ^a	0 ^d	0.46 ± 0.05^c	0.65 ± 0.05^d

The number represents inhibition diameter (cm, mean ± SD), each letter represents significant differences (post hoc Tukey, P < 0.05) n = 6
^a, ^b, ^c, ^dLetters are representing significant differences too. Only that in this case the analysis was made between all the treatments and comparing among them
