Abstract

The densities of adhesion of Staphylococcus epidermidis, Staphylococcus aureus and Serratia marcescens to five types of plastics were studied in relation to interfacial free energies at the aqueous interfaces of both the bacteria and the plastics. The free energy of adhesion of bacteria to plastic in an aqueous medium is a linear function of partititon of the bacteria between the solid surface and the liquid phase. These results show that the thermodynamics of the partitioning of a suspended particle between two immiscible liquid phases also apply to partitioning between a liquid and a solid phase.

摘要

研究了表皮葡萄球菌、金黄色葡萄球菌和粘质沙雷氏菌对五种塑料的粘附密度,并将其与细菌和塑料水界面处的界面自由能相关联。在水介质中,细菌与塑料的粘附自由能是细菌在固体表面和液相之间分配的线性函数。这些结果表明,悬浮颗粒在两个不混溶液相之间分配的热力学也适用于在液体和固体相之间的分配。
