摘要：

The wettability of AISI 304 stainless steel with 2B and 2RB surface finishes expressed in terms of the solid surface free energy (gamma(S)) was investigated with respect to the cleaning process. It was shown that cleaning affects the wettability of a solid surface. Depending on the cleaning method, gamma(S) ranged from 43.4 to 277.8 mJ m-2 for the 2RB surface and from 34.4 to 122.8 mJ m-2 for the 2B surface. There was no direct relationship between the number of adhering bacteria and gamma(S) or the wettability of solids. However, it was found that the adhesion of Streptococcus thermophilus was driven by a balance between gamma(S)d and gamma(S)P. The experimental results are as expected based on thermodynamic predictions when the spreading pressure (pi(c)) is accounted for in the surface free energy of bacteria, gamma(B), determination.
