dc.description.abstract | Cyanobacteria release polysaccharides that accumulate in the culture medium. In this study, released polysaccharides were isolated from the spent culture medium of an Arthrospira farm with a carbohydrate concentration of 136 mg L−1. The polysaccharides were concentrated 5.2 times by ultrafiltration using a 50 kDa polysulphone membrane and purified (desalting, protein removal). The polysaccharides were rich in uronic acid (159 mg g−1), had a low sulfate content (2.3 mg g−1), and contained 9 different monosaccharides, with 2-deoxy-d-galactose (27.9 %), fucose (22.7 %), glucose (22.0 %), and glucuronic acid (17.1 %) being dominant. A 1 % w/v polysaccharide concentrate formed stable gel beads in Al3+ and Fe3+ solutions. Rheological characterization of the gel revealed stable storage (G' = 38 Pa) and loss modulus (G" = 6 Pa) over a wide frequency range. This study demonstrates the feasibility to recover polysaccharides from Arthrospira spent culture medium and the potential to use these polysaccharides in food or biotechnological applications. | - |
