Melanized fungi (Chernobyl "radiation-eating" fungi): uses in research

Also: radiotrophic fungi, Cladosporium sphaerospermum, black fungi, melanin fungi

Dark, melanin-rich fungi grow on and around the Chernobyl reactor. Studies led by Ekaterina Dadachova found radiation can change melanin and enhance growth of some species. A 2018-2019 ISS experiment tested Cladosporium sphaerospermum as a possible radiation shield.

Radiation boosts melanized fungi growth

Dadachova and colleagues found ionizing radiation changed melanin's electronic properties and enhanced growth of melanized fungi.
