Which of the Following is True of All Biofilms

Question

Which of the following is true of all biofilms?
A) They only contain a single species.
B) The EPS are composed of proteins.
C) Cells in the biofilm are dormant until the bacteria leave the biofilm.
D) The EPS is secreted by the bacteria.
E) It is a continuous monolayer surface deposit.

Accepted Answer

All biofilms have an extracellular polymeric substance (EPS) that is secreted by the bacteria. This EPS is composed of a variety of molecules, including polysaccharides, nucleic acids, and lipids. It is a key component of the biofilm matrix and is responsible for the adhesion and cohesion of the bacterial cells within the biofilm.
