Synthetic polymers are gradually being replaced by biodegradable materials especially those derived from replenishable, natural resources [1]. Natural biopolymers have several advantages, such as availability from replenishable agricultural or marine food resources, biocompatibility, and biodegradability, thereby leading to ecological safety and the possibility of preparing a variety of chemically or enzymatically modified derivatives for specific end uses. Polysaccharides, as a class of natural macromolecules, have the tendency to be extremely bioactive and are generally derived from agricultural feedstock or crustacean shell wastes
