Résumé :
|
The initial event in biofilm formation on marine surfaces is the adsorption of an organic layer. This is followed usually by microorganisms and more developed forms, but there appears to be no obligatory order in this succession. The influence of the substratum chemistry on the rate and the extent of adhesion of microorganisms is still not fully agreed because many types of organisms in differing physiological states have been used, making consensus difficult. Support for the hypothesis that the biofilm matrix polymers are not the adhesives involved in the initial attachment of cells to surfaces is growing. Practical interest in the adhesion of marine microorganisms derives from their role in the degradation of man-made structures. A film of organisms only a few microns in thickness causes the hydrodynamic drag on a ship to increase considerably. Investigations of the means by which marine microorganisms adhere to surfaces have been taking place for more that 50 yr., yet we still do not understand completely the mechanisms involved.
