Production of Bioactive Compounds from Marine Bacteria

Abstract

This study is a trial to isolate new producers for biologically active compounds namely bacterial exopolysaccharids. In Egypt, studies on hyber saline systems were focused on famous and wide areas like Wadi El-Natron so the search in this study was directed to small regions beside Suez Canal. According to our knowledge this is the first report describing C. salexigensas levan producer in a considerable amount when compared with the international studies describing the production of levan from halophilic bacteria. The production of levan by C. salexigens has the advantages of lowering the contamination during different stages of fermentation process because the high salt concentration and low temperature during most stages of production. It is also economically effective because the previous reason and the ability of this microbe to produce levan from molasses as cheapest substrate. Resulted levan showed biological activity as anti-tumor, anticoagulant and prebiotic in addition to the ability to entering the biofilm formation process.
