Chitosan Properties and Application of Uses

Since chitosan is a polymer with the effect o high bioactivity and high biodegradable deacetylated amino groups, having capability of creating film and capacity of chelation, high adsorption capacity, high biocompatibility, antimutagenic and antitumor effect and due to other physicochemical properties, it has found its place in several applications of areas. If it is necessary to mention these properties, antibacterial properties can be mentioned in the first place. This property may vary according to type of bacteria, chitosan concentration, environment pH, solution
type used for chitosan, molecular weight of chitosan and degree of deacetylation.

Very effective results arising from polycationic natural structure in chitosan types up to L4 o/o of generally depolymerization have been obtained. In addition to this, antibacterial activity of low molecular weight chitosan is greater when compared with medium or high weight. The higher chitosan concentration, the more inhibition effect in bacterial killing property. It has been reported that this has exhibited more active and strong effect in microorganisms with no chitosan or its derivatives in its structure. (Kumar, 2000J.
