Abstract Bacterial proliferation in the form of biofilm fixed on a substrate is the result of a set of physical, chemical and biological processes. Microbial adhesion to a substrate is often considered to be the result of physicochemical interactions between the substrate and the microbial cells. These interactions include electrostatic interactions, Van der Waals interactions and acid-base interactions (electron donor - electron acceptor). The exact role of these physicochemical properties is still poorly documented. The purpose of this work is to provide some clarifications on this subject. The phenomenon of adhesion is often studied on clean surfaces, whereas in reality, it is always conditioned depending on its environment (medical, food or cosmetic). This is why in the present work we treated two different surfaces: glass and polyethylene, with diverse surfactants: nonionic, anionic and cationic. The choice of surfactants was motivated by its wide application in different fields. The physicochemical properties of the two substrata (treated and untreated) were defined using contact angle measurements. Moreover, the adhesive behavior of Staphylococcus aureus, as a bacterial model, on the studied substratum was assessed. The obtained results indicate that the physicochemical parameters of the two supports have changed in a specific way to each surfactant. The non-ionic surfactant turned both the surfaces more hydrophilic. However, the anionic and cationic surfactants have reversed the physicochemical characteristics of the surfaces. The correlation coefficients of the physicochemical properties and the adhesive behavior show that there is an association between the wettability of the two surfaces and the rate of the adherent cells.

不同表面活性剂处理的玻璃和聚乙烯表面的理化特性及其对细菌粘附的影响

摘要 以生物膜形式固定在基质上的细菌增殖是一系列物理、化学和生物过程的结果。微生物对基质的粘附通常被认为是基质与微生物细胞之间物理化学相互作用的结果。这些相互作用包括静电相互作用、范德华相互作用和酸碱相互作用（电子供体-电子受体）。这些物理化学特性的确切作用仍然鲜有记载。这项工作的目的是就这个主题提供一些澄清。粘附现象通常在干净的表面上进行研究，而实际上，它总是取决于其环境（医疗、食品或化妆品）。这就是为什么在目前的工作中我们处理两种不同的表面：玻璃和聚乙烯，具有多种表面活性剂：非离子、阴离子和阳离子。表面活性剂的选择是由于其在不同领域的广泛应用。使用接触角测量来定义两种基质（处理的和未处理的）的物理化学性质。此外，评估了作为细菌模型的金黄色葡萄球菌对所研究基质的粘附行为。所得结果表明，两种载体的理化参数对每种表面活性剂都有特定的变化。非离子表面活性剂使两个表面都更加亲水。然而，阴离子和阳离子表面活性剂逆转了表面的物理化学特性。
