Bacteria are ubiquitous and their versatility allows them to live in virtually every known habitat. Their pervasive nature has invariably had a tremendous effect on the environment in which they live, consequently changing the earth's landscape. Understanding the factors that influence the interactions between bacteria and solid surfaces could help scientists predict the impact on natural and engineered processes and to determine the factors that could either enhance, modify, control or inhibit bacterial adhesion. In this study the phospholipid method was adapted to accurately quantify the number of viable planktonic cells and the number of adhered cells in different systems. The method was applied to a study of some of the factors that control the adhesion of E. coli onto glass, muscovite and hematite. The approach used in this study systematically quantified bacterial adhesion under different conditions to determine the factors that are more important to the adhesion process. From this study it was determined that the chemical composition of the aqueous media strongly influences the surface properties which, in turn, control the adhesion process.
