The attachment of microorganisms to surfaces is one criterion for a biofilm. Going back in the literature, J.W. Costerton [1] was one of the pioneers in biofilm work. In 1978 he claimed that bacteria are mostly surrounded by extracellular polysaccharides, a “glycocalyx” which may act as a barrier against antibiotics, the bacteria form organized communities. Thus, biofilms can be simply defined as communities that are attached to a surface [2]. They exist as single- and multi-species biofilms [2], with the latter form being the most dominant.
