Bacterial adhesion under static and dynamic conditions

Bacterial adhesion is enhanced as a result of an increase in hydrophobicity of cells and substrates producing greater attractive forces. On negatively charged surfaces of glass and Teflon, the deposition of different pseudomonads and coryneform bacteria with varying hydrophobicities and negative cell surface charges is examined. For static batch systems the level of deposition is 5 times 10 to the 4th power and 3.6 times 10 to the 7th power cells per square centimeter, while for dynamic column, the level of deposition is 5 times 10 to the 4th power and 1.6 times 10 times 7 cells per centimeter squared.
