Although microbial exopolysacchaides (EPSs) have been intensively studied during the last two decades, the knowledge on these compounds is still scarce due to the phylogenetic diversity of microbial producers and the complexity of their molecules. Halophilic producers have been described in both bacterial and archaeal domains. Most of them require sugar and organic nitrogen for high yield synthesis. Halophiles synthesize molecules containing different monosaccharides, aminosugars, sulphates, uronic acids. Investigations into the halophilic EPS properties reveal their biotechnological potential in the field of the bio-medical applications, food products as emulsifiers and gelling agents, bioremediation for removing of toxic compounds, heavy metal removal, and in the petroleum industry for an enhanced oil recovery. The current review aims to increase the basic knowledge on EPS production by halophiles focusing on the recent investigations on halophilic producers of EPSs, culture conditions for attaining high yield, chemical composition and structure of their molecules, and the potential applications based on their physico-chemical properties read more ...
