Hotdog challenge study with surface-applied bacteriocin extracts comprising 3 mixed MOAs. L. monocytogenes 39-2 was either inoculated onto hotdogs alone (as control) or with added bacteriocin extracts (Trial #3). (A) bacteriocin extracts included curvaticin FS47, pediocin Bac3, enterocin FS56-1, and enterocin FS92. (B) bacteriocin extracts included curvaticin FS47, pediocin Bac3, enterocin FS56-1, and lacticin FLS1. Plate counts for LAB from these treatments were made on acidified MRS (hollow symbols). All sample treatments were performed in triplicate replication; data points represent the means and error bars represent the standard deviation from the means. Treatments with different letters are significantly different (repeated measures, p < 0.05).
