Question

Quizplus · Accepted Answer

All biofilms are characterized by the production of an extracellular polymeric substance (EPS), which is secreted by the bacteria and acts as a protective matrix for the community of cells. This EPS can be composed of various materials, including polysaccharides, proteins, lipids, and nucleic acids. Biofilms can contain multiple species of bacteria and are often highly structured, with different layers or zones of activity. The cells in a biofilm are typically not dormant, but are actively engaged in metabolic activity and communication with other cells in the community. A biofilm is not necessarily a continuous monolayer, as it can exist as discrete colonies or clusters of cells.
