The mention of bacteria usually brings to mind the picture of a swimming cell, however, most bacteria on earth are stuck to surfaces and form complex communities – biofilms.
Biofilms are responsible for myriad problems, including tooth decay and severe infections.
Biofilms need food to grow and survive, but, as they expand, the diffusion of nutrients becomes too slow.
www.mpg.deBei Bakterien denken wir häufig an schwimmende Zellen, aber die meisten bilden komplexe Gemeinschaften auf Oberflächen, sogenannte Biofilme.
Biofilme verursachen unzählige Probleme, darunter Zahnverfall und ernsthafte Infektionen.
Damit Biofilme wachsen und überleben, benötigen sie Nährstoffe; durch Diffusion allein würden sich diese in großen Biofilmen aber zu langsam verteilen.
