Exopolymeric substances (EPS) from Salmonella enterica: polymers, proteins and their interactions with plants and abiotic surfaces

When Salmonella enterica is not in a planktonic state, it persists in organised communities encased in extracellular polymeric substances (EPS), defined as biofilms. Environmental conditions ultimately dictate the key properties of the biofilms such as porosity, density, water content, charge, sorption and ion exchange properties, hydrophobicity and mechanical stability. S. enterica has been extensively studied due to its ability to infect the gastrointestinal environment. However, only during the last decades studies on its persistence and replication in soil, plant and abiotic surfaces have been proposed. S. enterica is an environmental bacterium able to effectively persist outside the human host. It does so by using EPS as tools to cope with environmental fluctuations. We therefore address this mini-review to classify those EPS that are produced by Salmonella with focus on the environment (plant, soil, and abiotic surfaces) by using a classification of EPS proposed by Flemming and collaborators in 2007. The EPS are therefore classified as structural, sorptive, surface-active, active, and informative.
