Gellan beads

Gellan gum is an exocellular polysaccharide that is secreted by Pseudomonas elodea. This gum had been investigated as tablet disin-tegrant, binder, gelling agent, and for controlled release. The release kinetics of amoxicillin from gellan beads follows the diffusion model for an inert porous matrix (24). [Pg.231]
