Episode notes
Black Fungi Thrive At Chernobyl
- Researchers found abundant black fungi growing inside and around Chernobyl, even in highly radioactive zones.
- These fungi cluster toward the most radioactive areas, a behavior called radiotropism.
Radiation Stimulates Fungal Reproduction
- Exposed Chernobyl fungi show increased spore production after radiation, called radio stimulation.
- Control fungi from noncontaminated areas lack this response, suggesting rapid adaptation.
Melanin Enables 'Radiosynthesis'
- Melanized fungi appear to harness ionizing radiation via melanin to fuel metabolism, a proposed 'radiosynthesis'.
- Irradiated melanin donates electrons more readily and may drive ATP production through electron transfer.
