Characterisation of Films Based on Exopolysaccharides from Alteromonas Strains ...
Concórdio-Reis, Patrícia; Pereira, João R.; Delgado Alves, Vitor; Nabais, Ana R.; Neves, Luísa A.; Marques, Ana C.; Fortunato, Elvira; Moppert, XavierThis work assessed the film-forming capacity of exopolysaccharides (EPS) produced by six Alteromonas strains recently isolated from different marine environments in French Polynesia atolls. The films were transparent and resulted in small colour alterations when applied over a coloured surface (ΔEab below 12.6 in the five different colours tested). Moreover, scanning electron microscopy showed that the EPS film...
Characterization and biotechnological potential of extracellular polysaccharide...
Concórdio-Reis, Patrícia; Delgado Alves, Vitor; Moppert, Xavier; Guezennec, Jean; Freitas, Filomena; Reis, Maria A.M.Marine environments comprise almost three quarters of Earth’s surface, representing the largest ecosystem of our planet. The vast ecological and metabolic diversity found in marine microorganisms suggest that these marine resources have a huge potential as sources of novel commercially appealing biomolecules, such as exopolysaccharides (EPS). Six Alteromonas strains from different marine environments in French ...
Structure, rheology, and copper-complexation of a hyaluronan-like exopolysaccha...
Martin-Pastor, Manuel; Ferreira, Andreia S.; Moppert, Xavier; Nunes, Cláudia; Coimbra, Manuel A.; Reis, Rui L.; Guezennec, Jean; Novoa-Carballal, RamonMO245 exopolysaccharide (EPS) was produced in laboratory conditions from Vibrio genus microorganism isolated from bacterial mats found in Moorea Island. Its structure consists of a linear tetrasaccharide repeating unit →4)-β-D-GlcpA-(1→4)-α-D-GalpNAc-(1→3)-β-D-GlcpNAc-(1→4)-β-D-GlcpA-(1→ containing covalently-linked 5% of glucose, galactose, and rhamnose, determined by methylation analyses and NMR spectroscopy....
