Optimizing Bioluminescence: choose your strain carefully

IMG_0116

Here are three stains of the bioluminescent bacterium Photobacterium phosphoreum. Identical growth conditions and growth stages, striking differences in light output. BioArtists choose your strain carefully! The upper most, and brightest strain, is the one that I use in my works. Its designation is P. phosphoreum HB (hyper bright) and it has been especially selected for its high level of bioluminescence.
