摘    要:研究了在体外状态下,不同粒度的低聚木糖(常规和超微下粉碎)对大肠杆菌、金黄色葡萄球菌和沙门氏菌3种常见的猪源性致病菌的抑菌效果.结果表明,不同粒度的低聚木糖均能抑制3种致病菌的生长.常规低聚木糖对大肠杆菌、金黄色葡萄球菌和沙门氏菌的最小抑菌浓度(MIC)分别为20.0、17.5和25.0 mg·mL~(-1);超微低聚木糖对大肠杆菌、金黄色葡萄球菌和沙门氏菌的MIC分别为20.0、20.0和30.0 mg·mL~(-1).可见,不同粒度的低聚木糖对3种致病菌均有抑菌作用.

关 键 词:低聚木糖  粒度  致病菌  最小抑菌浓度

Abstract:The experiment was conducted to investigate the inhibition effect of xylo-oligosaccharide with different particle size ( com-mon xylo-oligosaccharide and supermicrocrushed xylo-oligosaccharide ) on swine pathogenic Escherichia coli, Staphylococcus aureus and Salmonella typhimurium in vitro. The result showed that xylo-oligosaccharide with different particle size inhibited proliferations of E.coli, S.aureus and S.typhimurium. The minimum inhibitory concentration (MIC) of common xylo-oligosaccharide was 20.0, 17.5 and 25.0 mg·mL-1 for E.coli, S.aureus and S.typhimurium, respectively, and MICs of supermicrocrushed xylo-oligosaccharide were 20.0, 20.0 and 30.0 mg·mL-1 for E.coli, S.aureus and S.typhimurium, respectively. It is concluded that xylo-oligosaccharide ex-hibited inhibition effect on 3 species of swine pathogenic bacteria.
Keywords:xylo-oligosaccharide  particle size  pathogenic bacteria  minimum inhibitory concentration
