To answer: The term quorum sensing and its relation to biofilm formation. Introduction : “Quorum sensing” is defined as the “regulation of gene expression” in response to fluctuations in “cell-production density”. In bacteria, it releases chemical signals called auto inducers that increase in concentration as a function of cell density.
