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.

Dadachova and Casadevall reviewed how fungi survive, adapt to and possibly exploit ionizing radiation with melanin.

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