WebANTIMICROBIAL AND ANTIOXIDANT PROPERTIES OF CHITOSAN by PALLAVI CHHABRA (Under the direction of Dr. Yao-wen Huang) ABSTRACT The effect of chitosan as coatings for evaluating the antimicrobial and antioxidant effects on raw oysters was evaluated over a 12 to 15-day storage at 4 ºC. Four chitosan WebChitosan also caused leakage of glucose and lactate dehydrogenase from E. coli cells. These data support the hypothesis that the mechanism of chitosan antibacterial action involves a cross-linkage between the polycations of chitosan and the anions on the bacterial surface that changes the membrane permeability.
