Listeria monocytogenes Biofilms in the Wonderland of Food Industry

Angelo Colagiorgi et al. Pathogens. .

Abstract

The foodborne pathogen Listeria monocytogenes is a concern in food safety because of its ability to form biofilm and to persist in food industry. In this mini-review, the issue represented by this pathogen and some of the latest efforts performed in order to investigate the composition of biofilms formed by L. monocytogenes are summarized.

Keywords: Listeria monocytogenes; biofilms; extracellular matrix; food industry; food safety.

Schematic representation of the biofilm development stages. (a) The first step involves planktonic cells reversible attachment to surfaces; (b) the adhered cells begin to form a monolayer and to produce extracellular matrix; (c) the cells within the self-produced extrapolymeric matrix continue to grow and form multilayered microcolonies; (d) cells are irreversibly attached to the surface and embedded in the matrix: the biofilm is mature; (e) in the last stage of biofilm formation, cells are able to detach from the biofilm and to return in planktonic form, ready to colonize new surfaces.
