Ionized Calcium 및 Chitosan의 혼합처방에 따른 항균효과에 관한 연구 = Studies of Antibacterial Effect of the mixture of Ionized Calcium and Chitosan

다국어 초록 (Multilingual Abstract)

The antibacterial effects of chitosan depend on its molecular weight. The inhibition rate of bacteria growth of designated high in Gram positive, which was high in S aurens, S. epidermidis and Bacillus subtilis, low in S. mutans, high in C. albicans in fungi, low in A. niger. The inhibition rate of bacteria growth of chitosan was comparatively high in Gram positive, low in S. mutans and it showed high numerical value in C. albicans of fungi. The rate recorded good result at molecular weight 200,000 relatively, there was no difference, according to the molecular weight. The inhibition rate of bacteria growth according to the concentration of the increased differently between 1,000~10,000㎍/㎖, it showed antibacterial activity close to the inhibition rate of growth of chitosan rather than ionized calcium. The minimum inhibitory concentration marked the highest in the mixture of cihtosan and ionized calcium for all kind of bacteria generally, there was a little difference between yeast and fungi.
