EXOPOLYSACCHARIDE RELEASED BY LACTIC ACID BACTERIA ISOLATED FROM CAMEL MILK

Abstract

Lactic acid bacteria (LB) are a type of microorganism capable of fermenting organic molecules to attract the energy essential for its growth, but during the course of different metabolic reactions various molecules with biological activities are synthesized; peptides, exopolysaccharides, fatty acids and organic acids. Because of the bioactivity of these biomolecules, they are widely used in the pharmaceutical and agri-food sectors (improving the flavour of fermented foods, increasing its nutritional value and increasing its shelf life…etc). On the other hand, numerous studies have reported the use of camel milk in the treatment of human diseases. Its nutritional value and its technological characteristic are due to its composition rich in vitamins, proteins, minerals, lactic acid bacteria and the bioactive metabolites of these bacteria, among these biomolecules the exopolysaccharide. Furthermore, research has shown that the type of bioactive molecules synthesized by BL is dependent on several parameters e.g. pH, temperature, salinity and composition of the environment, for this reason the analysis of EPS bioactivity released by BL isolated from camel milk becomes a recommended subject of research The article enlightens recent data at EPS as bioactives molecules in different sectors.
