The number and distribution of G residues in the alginate polymer must reflect, at some level, the activity and specificity of the mannuronan epimerase. Alginate from P. aeruginosa differs from that isolated from A. vinelandii and seaweed, in that the G content is lower, and the G residues are randomly distributed throughout the polymer. Alginate from A. vinelandii and seaweed has a block structure in which tracts of M residues are interspersed with tracts of G residues, and some regions of the polymer have diads of alternating M and G. 

Entrapment of Candida tropical is whole cells in ionic polymeric networks has been achieved using different types of polyelectrolyte polymers (alginates, carbomethylcellulose, synthetic maleic acid copolymers) and multivalent counterions (e.g.. Ar ). Oxidative degradation of phenol served as a model reaction for a multienzyme catalytic process.

Many materials snch as ceramics, polymers, alginate, and polysaccharides have shown potential advantages as drug delivery systems. However, marine materials such as coral exoskeletons and marine shells show a better promise due to their easy... 

In most of acidic PE the ionizable moiety is the carboxylic group. Such is the case of carbomers (C, also known as carbopol or carboxyvinyl polymers), alginic acid (AA), hyaluronic acid (HA, also known as hyaluronan). Other acidic PE such as dextran sulfate, cellulose sulfate and nucleic acids are based on sulfate, or phosphoric ionizable groups. 

In a separate approach, hydrogel association of natural polymer (alginate) molecules could be performed in the presence of Ca +, for example, using liposomes as nanocontainers [10]. Alginate nanogels of 120-200 nm were obtained after removal of lipid bilayer by addition of surfactant. Nanogel size can be tuned by varying the nanocontainer volume and further controlled by the addition of monovalent salt to the dispersion.
