ABSTRACT

The exopolysaccharide (EPS) synthesized by the extreme halophylic archeon Haloferax mediterranei is an interesting substance due to its preservative features and to its capacity to form films. This study aims to evaluate the antibacterial activity of EPS and to test its adhesion on organic surfaces, as calamari and shrimp meat, in order to use it as preservation biofilm. The results indicates a good antimicrobian action on Escherichia coli, followed by Salmonella anatum and no antibacterian activity against Pseudomonas aeruginosa. The film obtained from EPS is discontinuous, distributed no uniformly on the surface of the meat.

Keywords: Haloferax mediterranei, biofilm, antimicrobial proprieties.
