Natural environment

Luminescent bacteria can be isolated from sea-water and from sea-fishes. This is the method of isolation of luminescent bacteria from fish:

The sea-fish body should be partially plunged in the salt solution (or sea-water) and stored in the refrigerator (in the temperature 4 - 6C). After certain time the colonies of luminous bacteria will grow on the surface of fish body. These colonies can be isolated to obtain pure cultures.

(on the base of book "Mokrobiologia ogolna" by H. G. Schleger)

I must say, that I have not applied this method yet and I don't know if this method is effective.

Some of luminescent bacteria can live in symbiosis with marine organisms. For example some species of deep-sea fishes and cuttle-fishes have luminous organs in which luminous bacteria live.

Luminous bacteria can grow in more unusual places too:
