This project details the characterization of MRE002, a unique strain of Vibrio fischeri found in the light organ of a Hawaiian bobtail squid.  Average CFU/mL, luminescence levels in presence of autoinducer, motility, ability to conjugate, and luminescence levels from a squid single-strain colonization will be demonstrated.  In addition, differences in the luxIR region of the bacterial genome between MRE002 and the positive control ES114 will be highlighted.
