| 摘 要： | 目的:研究壳寡聚糖对变形链球菌细胞表面疏水性的影响,从而进一步了解壳寡聚糖影响细菌黏附的机制。方法:使用不同浓度(10-2、10-1、1g/L)的壳寡聚糖溶液处理变形链球菌,并采用微生物黏着碳氢化合物法测试细胞表面疏水性。结果:随壳寡聚糖浓度增加,变形链球菌ATCC25175细胞表面疏水性有显著性降低。结论:壳寡聚糖可能通过降低细菌表面疏水作用而抑制变形链球菌的黏附。

| Abstract: | AIM:To study the effect of chitooligosaccharide on cell-surface hydrophobicity of Streptococcus mutans .METHODS:Microbial adhesion to hydrocarbons (MATH) was used to measure the cell-surface hydrophobicity of Streptococcus mutans in presence of different concentrations of chitooligosaccharide(10 -2 ,10 -1 ,1 g/L).RESULTS:The cell-surface hydrophobicity of Streptococcus mutans ATCC25175 decreased following the increasing of chitooligosaccharide.CONCLUSION:Chitooligosaccharide may inhibit the adherence of Streptococcus mutans by way of changing its cell-surface hydrophobicity. |
