Chitosan is the N-deacetylated deri

Chitosan is the N-deacetylated derivative of chitin, is a
natural polymer composed of b-(1,4)-2-acetamido-2deoxyD-glucose
and b-(1,4)-amino-2-deoxy-D-glucose
units. The positive charge of chitosan confers to this polymer
numerous and unique physiological and biological
properties with great potential in a wide range of industries
such as pharmacology, medicine and agriculture

os et al., 2006; Rinaudo, 2006). The antimicrobial
activity of chitosan has been considered in a wide
variety of microorganisms. Diverse studies have shown
the effect of molecular weight and concentration of chitosan
on antibacterial activity (Liu et al., 2006; No, Park,
Lee, & Meyers, 2002; Zheng & Zhu, 2003). On the other
hand, the antifungal activity and its ability to extend the
storage life of fruits and vegetables has been demonstrated

and concentration caused mycelial growth inhibition (25
90.5%) in Penicillium digitatum and Penicillium italicum

ster, & Sommer,
2002; Northover & Zhou, 2002). The search of
natural alternatives for the control of postharvest commodities
has been improved, and option such as chitosan
has been evaluated (Tripathi & Dubey, 2004).
