Effect of Ultrahigh Vacuum on Viability of Microorganisms

Effect of Ultrahigh Vacuum on Viability of Microorganisms

Three species of resistant microorganisms were exposed for 5 days to an ultrahigh vacuum approaching that of interplanetary space. Since no lethal effect was observed, there is no indication that the vacuum of outer space would prevent transport of viable microorganisms on unsterilized space vehicle...

Zusammenfassung:Three species of resistant microorganisms were exposed for 5 days to an ultrahigh vacuum approaching that of interplanetary space. Since no lethal effect was observed, there is no indication that the vacuum of outer space would prevent transport of viable microorganisms on unsterilized space vehicles.
