    1. Introduction
    Given the importance of this WST-1 Cell Proliferation Colorimetric Assay Kit topic, the aim of the present study was to perform an “in vitro” evaluation of the antibacterial activity of a bacteriocin-like substance (BLS) produced by Lactobacillus pentosus 39 against some indicators, including psychotropic microorganisms, such as L. monocytogenes and A. hydrophila. Subsequently, we also assessed the improvement of safety of fresh salmon fillets artificially contaminated with divergent evolution two pathogens in the presence of the Lb. pentosus 39 protective culture or BLS as biopreservatives, as indicated by the antibacterial activity of samples stored at refrigeration temperatures and under simulated cold chain break conditions.
