Vibrio fischeri imports and assimilates sulfate during symbiosis with Euprymna scolopes.

ABSTRACT: Sulfur is in cellular components of bacteria and is, therefore, an element necessary for growth. However, mechanisms by which bacteria satisfy their sulfur needs within a host are poorly understood. Vibrio fischeri is a bacterial symbiont that colonizes, grows, and produces bioluminescence within the light organ of the Hawaiian bobtail squid, which provides an experimental platform for investigating sulfur acquisition in vivo. Like other γ-proteobacteria, V. fischeri fuels sulfur-dependent anabolic processes with intracellular cysteine. Within the light organ, the abundance of a ΔcysK mutant, which cannot synthesize cysteine through sulfate assimilation, is attenuated, suggesting sulfate import is necessary for V. fischeri to establish symbiosis.
