• Abstract:

  Biofilms are result of a natural tendency of microorganisms to attach to surfaces (biotic and abiotic), to multiply and to embed themselves in a slimy matrix of extracellular polymeric substances (EPS). The attachment of microorganisms to surfaces is a very complex process. As biofilm matures, detachment and growth processes come into balance leading to a constant amount of biomass on the surface but also to the release of biofilm cells. These enable the colonization of neighbour surfaces and the formation of new biofilm communities. EPS in biofilm systems are responsible for binding cells and other particulate materials together. The successful adaptation of bacteria to changing natural conditions requires also that the microorganism can sense and respond to its external environment and modulate gene expression accordingly. Even if biofilms are probably the first form of community life on Earth, the incorporation of scientific aspects on biofilm science and technology in teaching content is a challenge task as this research field is constantly evolving.
