Table 1. Anti-listeria activity of different Ply500 formulations against L. innocua assessed after incubation with 1 mL of a suspension containing 10⁵ CFU/ml^a.

Ply500 Formulation	Log CFU reduction after 24 h	Retention of native enzyme activity (plating assay) as a percentage relative to native enzyme	Retention of native enzyme activity (cell wall assay) as a percentage relative to native enzyme
Ply500 (20 μg/ml)	4.7 ± 0.05	100%	100%
Ply500-SNP (60 μg/ml)	4.6 ± 0.02	33	n.d.^b
Ply500 film (500 μg/ml)	1.6 ± 0.12	3.9 ± 0.05	n.d.^b
FP (20 μg/ml)	0.3 ± 0.02	51 ± 4	4.5 ± 0.5
FP₁₀(20 μg/ml)	2.5 ± 0.30	99 ± 0.5	32 + 4.0
FP₁₀-starch nanoparticle (80 μg/ml)	2.9 ± 0.18	24 ± 0.02	n.d.^b

^aListeria cells were grown in BHI media for 7 h. Standard deviations were calculated from triplicate measurements. No significant killing was observed with controls of SNP-NCO, overnight wash of Ply500-SNP, Film (without Ply500), overnight wash of Ply500 film, MBP, starch nanoparticles, and MBP-starch nanoparticles. The concentration (in μg/mL) in column one represents the Ply500 content of the formulation.

^bnot determined.
