Therefore bacteria in biofilms express genes differently when compared with similar bacteria as planktonic cells. Some of the genes that are up-regulated are involved in the secretion of EPS.

The most crucial difference between a bacterial biofilm and free-floating (planktonic) single-cells living in liquid suspensions is the biofilm’s dramatically increased chemotolerance. This has been ...

Bacteria often live in multicellular communities known as biofilms. Unlike their planktonic counterparts, bacteria in biofilms are encapsulated in an extracellular matrix, a complex mixture of ...
