Marine biomolecules: a promising approach in therapy and biotechnology

Abstract

The marine environment is characterized by a wide diversity of microorganisms among which marine bacteria. To insure their survival in hostile conditions where they face high competition with pathogenic microorganisms, they produce various kinds of bioactive molecules within biofilms with unique structural and functional features. As example: marine peptides which provide a broad spectrum of antimicrobial, antitumoral, antiviral and anti-inflammatory activities, in addition to marine exopolysaccharides showing antifouling and antifungal activities, immunomodulatory properties, emulsion stabilization capacity with other various potentials. Some biofilms have shown a beneficial role for aquaculture, among which enhancement of growth performance and improvement of water quality, while others are threatening not only aquaculture and maritime fields, but also medicine and food industry. Thus, marine bioactive compounds are promising preventing agents for the establishment and growth of fouling microorganisms, which may be useful in different fields in order to decrease economic losses and avoid foodborne illnesses.
