Radiation-Eating Fungi Found

BRONX, New York, May 23, 2007 (ENS) - Researchers=20
at the Albert Einstein College of Medicine have=20
discovered that fungi that have the ability to=20
use radioactivity as an energy source for making=20
food and spurring their growth.

The finding could trigger recalculation of=20
Earth's energy balance and the scientists say the=20
ability of fungi to live off radiation could=20
prove useful to venturing into outer space.

"Since ionizing radiation is prevalent in outer=20
space, astronauts might be able to rely on fungi=20
as an inexhaustible food source on long missions=20
or for colonizing other planets," says Dr.=20
Ekaterina Dadachova, associate professor of=20
nuclear medicine and microbiology and immunology=20
at Einstein and lead author of the study.

The research began five years ago when Dr. Arturo=20
Casadevall, chair of microbiology and immunology=20
at Einstein, read on the Internet that a robot=20
sent into the still highly radioactive damaged=20
reactor at Chernobyl had returned with samples of=20
black, fungi rich in melanin that were growing on=20
the reactor's walls.

Those fungi that are able to "eat" radiation must=20
possess melanin, the pigment found in many if not=20
most fungal species. But up until now, melanin's=20
biological role in fungi, if any, has been a=20
mystery.
