Figure 2. Impact of luxI deletion on growth of Vibrio fischeri in isolation.

Batch culture growth of V. fischeri wild type strain MJ1 (circles) and luxI deficient mutant strain MJ211 (squares) in the absence (A) and presence (B) of 5 µM N-3-oxohexanoyl-L-homoserine lactone. Values presented are averages of triplicate cultures. Error bars represent standard deviation. Small statistically significant differences were late in the logarithmic phase of growth.
