Abstract(s)
Microbial extracellular polysaccharides (EPS), produced by a wide range of bacteria, are
high molecular weight biopolymers, presenting an extreme diversity in terms of chemical
structure and composition. They may be used in many applications, depending on their
chemical and physical properties. A rather unexplored aspect is the presence of rare
sugars in the composition of some EPS. Rare sugars, such as rhamnose or fucose,
may provide EPS with additional biological properties compared to those composed of
more common sugar monomers. This review gives a brief overview of these specific EPS
and their producing bacteria. Cultivation conditions are summarized, demonstrating their
impact on the EPS composition, together with downstream processing. Finally, their use
in different areas, including cosmetics, food products, pharmaceuticals, and biomedical
applications, are discussed
