Separation and Purification of Marine Polysaccharides

Over the past decades, marine organisms including macroalgae and microalgae have been widely explored as potential sources of bioactive compounds with applications in various fields such as pharmaceuticals, biomedicine, cosmetics, and food. Marine polysaccharides, such as chitin/chitosan, sulfonan, fucoidan, alginate, and carrageenan, are biochemical compounds with several important properties. Marine polysaccharides are complex carbohydrates derived from marine sources such as seaweed, microalgae and shellfish. These biomolecules have attracted great attention due to their diverse beneficial properties and potential applications in various industries. CD BioSciences focuses on providing comprehensive services for the isolation and purification of marine polysaccharides, unlocking their great potential in scientific research and industrial applications. Our scientists use different bioprocess engineering methods to produce polysaccharides from microorganisms. The main modes of operation for laboratory bioreactors and pilot plant implants are batch, fed-batch and continuous.
