摘要: The unicellular cyanobacterium Cyanothece sp. CCY 0110 is a highly efficient producer of extracellular polymeric substances (EPS), releasing up to 75% the polymer culture medium. carbohydrate released medium (RPS) was previously isolated and characterized; it composed nine different monosaccharides including two uronic acids, also containing peptides sulfate groups. Here shown that RPS spontaneously assembles with proteins at high concentrations leading phase transition. are progressively structurally intact near physiological conditions, primarily through swelling polymer-protein matrix. kinetics can be modulated addition divalent cations, such as calcium. Notably, not toxic human dermal neonatal fibroblasts in vitro bellow 0.1 mg mL-1 . results show this good candidate for delivery therapeutic macromolecules.
