@misc{10481/33536, year = {2010}, url = {http://hdl.handle.net/10481/33536}, abstract = {We have studied the exopolysaccharide produced by the type strain of Salipiger mucosus, a species of halophilic, EPS-producing (exopolysaccharide-producing) bacterium belonging to the Alphaproteobacteria. The strain, isolated on the Mediterranean seaboard, produced a polysaccharide, mainly during its exponential growth phase but also to a lesser extent during the stationary phase. Culture parameters influenced bacterial growth and EPS production. Yield was always directly related to the quantity of biomass in the culture. The polymer is a heteropolysaccharide with a molecular mass of 250 kDa and its components are glucose (19.7%, w/w), mannose (34%, w/w), galactose (32.9%, w/w) and fucose (13.4%, w/w). Fucose and fucose-rich oligosaccharides have applications in the fields of medicine and cosmetics. The chemical or enzymatic hydrolysis of fucose-rich polysaccharides offers a new efficient way to process fucose. The exopolysaccharide in question produces a solution of very low viscosity that shows pseudoplastic behavior and emulsifying activity on several hydrophobic substrates. It also has a high capacity for binding cations and incorporating considerable quantities of sulfates, this latter feature being very unusual in bacterial polysaccharides.}, organization = {This research was supported by grants from the Dirección General de Investigación Científica y Técnica (BOS2003-00498; CGL 2005-05947) and from the Plan Andaluz de Investigación, Spain.}, publisher = {MDPI}, keywords = {Exopolysaccharides}, keywords = {Salipiger mucosus}, keywords = {Halophilic bacteria}, keywords = {Fucose}, keywords = {Sulfates}, title = {Characterization of the Exopolysaccharide Produced by Salipiger mucosus A3T, a Halophilic Species Belonging to the Alphaproteobacteria, Isolated on the Spanish Mediterranean Seaboard}, doi = {10.3390/md8082240}, author = {Llamas Company, Inmaculada and Mata Gómez, Juan Antonio and Tallón, Richard and Bressollier, Philippe and Urdaci, María C. and Quesada Arroquia, Emilia and Béjar Luque, María Victoria}, }
