Abstract Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density.

Many of these behaviors are regulated by aprocess known as quorum sensing. Each individual bacterium is capable of producing a signaling molecule (inducer) and each bacterium also has a receptor for the inducer. When the inducer binds to the receptor, it activates the transcription of certain genes, including those responsible for the synthesis of the inducer QUORUM SENSING IN BACTERIA Submitted to - Submitted by - Prof. H. K. Kehri Sameen Zaidi Prof. A. Dikshit Vandana Kumari M.Sc. III sem 2014 - 2015 2. WHAT IS QUORUM SENSING ? • ‘Quorum’ is a Latin word. • It means the number of members of a group required to be present to transact business or carry out an activity legally • In this Quorum sensing was firstly discovered in the marine bioluminescent bacteria Vibrio fischeri , which produce light only if cells are at high density. It has been discovered that intercellular communication play an essential role in the regulation of gene whose products are needed for establishment of virulence, symbiosis , Biofilm production, plasmid transfer &morphological differentiation in a wide range of microbes. Quorum sensing Luminous bacteria (e.g. Vibrio fischeri ) contain high levels of luciferase only when cultures reach the late-log phase of growth. Autoinduction Microorganisms producing pheromones and communicating with one another, was proposed.
