An evaluation of the kinetics and capacity of chitosan to trap lead and cadmium ions in aqueous solution was carried out at 25oC using concentration and contact time as parameters. The experiments were done as batch process. Our results show that the adsorption process is concentration-driven with high capacity of chitosan for the adsorption of these metal ions

A major advantage is chitosan's antimicrobial properties, which have been acknowledged since the 1970's but only recently probed in detail. Ri- cardo Muzzarelli, a pioneer of chitosan research, observed in 1990 that chitosan drastically inhibited the growth of 298 bacterial cultures.

The effect of shrimp and fungal chitosan on the growth and development of orchid plantmeristemic tissue in culture was investigated in liquid and on solid medium. The growth of meristem explants intoprotocorm-like bodies in liquid medium was accelerated up to 15 times in the presence of chitosan oligomer, the optimal concentration being 15 ppm. The 1 kDashrimp oligomer was slightly more effective compared to 10 kDashrimp chitosan and four times more active compared to high molecular weight 100 kDashrimp chitosan.

Chitosan (poly-D-glucosamine) is a polymer1 of glucosamine sugars, specifically glucosamine and N-acetyl- glucosamine (Hadwiger 2004). Its structure and composition are similar to both cellulose (i.e., the primary structural component of plant fiber) and chitin.

In this study, we investigate the potential of chitosan, a natural beta-1-4-linked glucosamine polymer, to reduce plant transpiration. Chitosan was appliedfoliarly to pepper plants and water use was monitored. Peppers were grown in pots ingrowth-chambers, where transpiration was measured by weighing pots. In an accompanying field study, water use was determined by monitoring soil moisture depletion with time domain reflectometry.

Chitosan is used primarily as a plant growth enhancer, and as a substance that boosts the ability of plants to defend against fungal infections. It is approved for use outdoors and indoors on many plants grown commercially and by consumers. The active ingredient is found in the shells of crustaceans, such as lobsters, crabs, and shrimp, and in certain other organisms
