摘要
Abstract
The antibiotic activities of α-chitosan with different molecular weights (MW=1.56×104, 3.3×104, 9.5×104 and 7.2×105) against such strains of bacteria as Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Clostridium perfringens commonly present in aquatic products as well as miscellaneous microbes on fish epidermis were studied in this paper. The experimental results demonstrated that α-chitosan showed its antibiotic activity indifferent degree and the antibiotic activity was enhanced with the decrease of average molecular weight of α-chitosan, α-Chitosan with MW=1.56×104 inhibited the growth of experimental microbes more effectively than others with MW=3.3×104 ,9.5×104 and 7.2×105.关键词
