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.

Both sets of squid were healthy. But those raised in the absence of the bacteria did not form mature light organs. Those with the bacteria present in their environment did form mature light organs. rapidly increase in number. nbc senate seats
