How do bacteria communicate in biofilms?

Cell to Cell Communication in a Biofilm. In the cartoon above, various species of bacteria are represented by different colors. Bacteria can produce chemical signals ("talk") and other bacteria can respond to them ("listen") in a process commonly known as cell-cell communication or cell-cell signaling.

So, do bacteria communicate?

Quorum sensing: cell-to-cell communication in bacteria. Bacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells.
