How is biofilm formed on shipwrecks
WebBiofilm Formation. In general, micro-organisms have the tendency to attach to surfaces and develop biofilms. A biofilm is an assemblage of surface-associated microbial cells that form an extracellular polymeric substance, named EPS-matrix. Therefore, a biofilm consists of highly hydrated and immobilized cells that stick to a substratum. Web1 sep. 2012 · It was found that mixed biofilm formation by Enterococcus relies on the presence of E. coli, which has a higher affinity and thus adheres more easily to surfaces. E. coli cells were observed to attach initially to a plastic stent surface, facilitating the attachment of Enterococcus and subsequent formation of a mixed biofilm (Leung et al ., 1998 ).
