Description
Biologists do not yet know why these bacteria produce light. One idea is that producing light gives these bacteria an advantage for survival. By glowing, they attract fish, which they then use as a host organism — the bacteria are able to live in the fish's body. These fish, which are attracted to the bacteria's light, pick up the bacteria and prevent them from settling on the bottom of the ocean, where there is less oxygen available. The fish might also benefit from allowing the bacteria to live in their body — the fish are able to glow due to the presence of luminescent bacteria, and this light might help them to spot food more easily in the dark ocean. Today we will streak luminescent bacteria on solid medium (agar plate) so that you will be able to see them grow and glow.
