Bioluminescence is a fascinating natural phenomenon which
allows organisms to produce their own light. This light can
range from a faint glow to a dazzling flash, depending on
the species and environmental conditions.
We are excited to introduce the bright world of
bioluminescence to you, and to answer any questions you may
have.
Q. How does it work?
A. Bioluminescence involves a chemical reaction
between a molecule called luciferin and an enzyme called
luciferase. When these
substances mix, a light-emitting reaction occurs. The
color and brightness of the light produced can vary
depending on the specific type of luciferin and
luciferase involved.
The light is emitted from the reaction through an
excited electron relaxing back to its ground state. The
energy difference between the excited and ground states
determines the color of the light emitted.
In the case of fungal bioluminescence, this electron is excited
through the creation and subsequent degradation of a peroxy
bridge within a ring structure. Pretty cool!
We will have a more detailed explanation of the chemistry
in an upcoming article. Stay tuned!
Q. Why do organisms bioluminesce?
A. Bioluminescent organisms have evolved
to use light at least 40 times throughout time, all for various
purposes, including:
- Communication: Bioluminescence can
be used to communicate danger, attract mates, or
send signals to others of the same species;
- Camouflage: Bioluminescence can be
used to blend in with other surrounding light in
their environment;
- Predation: Some organisms use
bioluminescence to attract prey, especially in the
deep dark depths of the water;
- Defense: Some organisms use
bioluminescence to startle or confuse its predators.
Q. Where can you find bioluminescence?
A. Bioluminescence can be observed in various
environments, from the depths of the ocean to terrestrial
forests.
- Marine Animals
such as fish, jellyfish, squid, and plankton;
- Insects
such as fireflies and glowworms;
- Bacteria
such as Vibrio fischeri;
- Fungi
such as N. nambi and O. olearius.
