摘要：

K-carrageenan oligosaccharides were prepared by enzymatic degradation. The inhibiting activities of the prepared kappa-carrageenan oligosaccharides against Escherichia coli(E.coli), Staphylococcus aureus(S.aureus), Saccharomyces cerevisiae (S.cere), Penicillium citrinum(P.citr) and Mucor.sp were determined and compared by measuring the inhibitory zone diameter. The results indicate that all tested kappa-carrageenan oligosaccharides have inhibiting activity against the five bacteria, but the inhibiting activities against Saccharomyces cerevisiae is higher than against any other four bacteria. The inhibiting concentration (MIC) of kappa-carrageenan oligosaccharides are 1 mg/ml, 5mg/ml, 20mg/ml, and antibacterial activity of kappa-carrageenan oligosaccharides was inversely affected by concentration, with the highest activity at the concentration of 5mg/ml.
