Symbiotic characterization of Vibrio fischeri ES114 mutants that display enhanced luminescence in culture

Abstract

Vibrio fischeri ES114 is a bioluminescent symbiont of the squid Euprymna scolopes. Like most isolates from E. scolopes, ES114 produces only dim luminescence outside the host, even in dense cultures. We previously identified mutants with brighter luminescence, and here we report their symbiotic phenotypes, providing insights into the host environment. © 2013, American Society for Microbiology.
