| Research Abstract |
The aim of this study is to evaluate the ecological significance of bacterial bioluminescence based on the analysis of light emission spectra shed by luminous bacteria isolated from various marine environments. Our data revealed that light emission spectra do not have the same shape, but display a few variations. In addition, our analyses showed that the bacterial strains with shorter maximum wavelength light emission (approximately <480 nm) have a lumazine protein, which is the substance responsible for modulating light emission spectra.
