Cyanobacterial extracellular polymers, compositions and uses thereof

摘要

Polysaccharides released from the unicellular cyanobacteria cyanoseis species CCY 0110 exhibit low cytotoxicity and have proven to be suitable for delivery of macromolecules. The cyanobacterial extracellular polymers disclosed in the present subject matter, ie polysaccharides, more specifically heteropolysaccharides, aggregate with proteins into a new phase of gel-like behavior, and the release kinetics are modulated by adding divalent cations ( Ie, can also be delayed) and / or exhibit physical and chemical properties typical of bioemulsifiers or bioflocculants.
