Comparative Analysis of the lux Operons in Aliivibrio logei KCh1 (a Kamchatka Isolate) and Aliivibrio salmonicida

Here we provide a molecular description of a new psychrophilic strain, KCh11, of marine luminescent bacteria classified as Aliivibrio logei. We sequenced the entire lux operon of A. logei KCh1 and showed that it is substantially similar to the lux operon of Aliivibrio salmonicida. It was demonstrated that the reduced production of bioluminescence in A. salmonicida is most likely defined by a specific defect in its luxD gene.
