The physiological role of EPS depends on the ecological niches and the natural environment in which microorganisms have been isolated. In this chapter, data on EPS production and the effect of EPS on corrosion of steel produced by Lactobacillus sp. are presented and discussed. Lactobacillus plantarum Ts was obtained from the Collection of Department of Biology, Shumen University. It was tested for its ability to produce exopolysaccharides when cultivated in a medium containing 10% sucrose. It could be underlined that 10% sucrose in the medium stimulated the process of protection of corrosion. Also, the biofilm in vitro in the combined cultivation of Staphylococcus aureus and the Lactobacillus plantarum Ts probiotic bacterium on the surface of different metal materials for fixed dental prostheses was investigated [unpublished results]. The structure of layer over steel plates was analyzed by scanning electron microscopy (SEM) JSM 5510. In our opinion, more detailed research is needed to be done in the future, and the possibilities should be analyzed for the creation of a thin biofilm from a probiotic bacterium or an exopolysaccharide this bacterium has produced, which would protect the implants against the growth of a pathogenic biofilm.
