Foxfire: Bioluminescent Fungi

Post by Dragon on Sat Mar 24, 2018 4:17 am

Foxfire, also sometimes called "fairy fire", is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to a luciferase, an oxidative enzyme, which emits light as it reacts with a luciferin. It is widely believed that the light attracts insects to spread spores, or acts as a warning to hungry animals, like the bright colors exhibited by some poisonous or unpalatable animal species. Although generally very dim, in some cases foxfire is bright enough to read by.

The oldest recorded documentation of foxfire is from 382 B.C., by Aristotle, whose notes refer to a light that, unlike fire, was cold to the touch. The Roman thinker Pliny the Elder also mentioned glowing wood in olive groves.[3]

Foxfire was used to illuminate the needles on the barometer and the compass of Turtle, an early submarine.[4] This is commonly thought to have been suggested by Benjamin Franklin; a reading of the correspondence from Benjamin Gale, however, shows that Benjamin Franklin was only consulted for alternative forms of lighting when the cold temperatures rendered the foxfire inactive.

After many more literary references to foxfire by early scientists and naturalists, its cause was discovered in 1823. The glow emitted from wooden support beams in mines was examined, and it was found that the luminescence came from fungal growth.

No one knows why mushrooms in northern Brazil glow at night. Researchers are using LED-lit mushrooms to mimic nature in order to find out.

David Attenborough introduces the perplexing world of glowing fungi and asks, is fungal bioluminescence just a biochemical accident or is there a more important function at play?

Why do animals produce light of their own? For centuries, we could only marvel at the mystery of bioluminescence. Now we can begin to reveal the amazing truth about these living lights. Sir David Attenborough is our guide, as we venture into a world he describes as "utterly unlike our own".
