' "All the space microorganisms found inside spaceships originated on
Earth," she said. "Most of them got into spacecraft on Earth and some of
them were brought aboard with the visiting crews. So, you would expect them
to behave like 'normal' Earthly fungi and bacteria."

This is not the case, however. Microorganisms in space significantly mutate.
One of the reasons for their mutation could be the level of radiation on
Mir, which is 500 times more intense than on Earth.

"Fungi and bacteria are dormant for a number of years and than suddenly
become active. Then they may become passive again, but overall their
aggressiveness exceeds this of the same type of microorganisms on Earth,"
said Novikova.

"We don't know what triggers their activation in space," Novikova said.
"Based on some observations we can say that the older the plastic is, the
more likely it will be used by microorganisms as their feeding ground. They
also become more aggressive after the increase of solar activity."


  Storing fungi

All the samples of space-grown microorganisms brought back to Earth are kept
at IBMP in sealed ampoules stored in safe places. "We don't know how they
will behave if they get back into regular Earth conditions," Novikova said.

There is one more reason, however, for keeping space mutants in specially
secured places. "If you take a space-grown microorganism which used metal as
a part of its habitat and keep cultivating it by increasing the content of
metal in its habitat, you can potentially get a destructive biological
weapon which will literally 'eat' arms," said Novikova.

(...)

(...) even the most effective disinfecting measures, like filling spacecraft
with an extremely toxic gas mixture, do not kill all the fungi and bacteria.


"Microorganisms get inside plastic where this mixture cannot reach them.
Than at some point during flight, the contaminated plastic just emits its
inhabitants into the station's atmosphere," said Novikova.
