WebFeb 20, 2024 · VIBRIO FISCHERI Quorum sensing was first observed in Vibrio fischeri, a bioluminescent bacterium that lives as a mutualistic symbiont in the photophore (or light-producing organ) of the Hawaiian bobtail squid. When Vibrio. fischeri cells are free-living (or planktonic), the auto inducer is at low concentration, and, thus, cells do not luminesce. WebFree-living V. fischeri do not luminesce. Why?
