Isolation of rpoB mutations causing rifampicin resistance in Bacillus subtilis spores exposed to simulated Martian surface conditions.

Astrobiology - 1 Dec 2008

Perkins Amy E, Schuerger Andrew C, Nicholson Wayne L

Abstract excerpt

ABSTRACT Bacterial spores are considered prime candidates for Earth-to-Mars transport by natural processes and human spaceflight activities. Previous studies have shown that exposure of Bacillus subtilis spores to ultrahigh vacuum (UHV) characteristic of space both increased the spontaneous mutation rate and altered the spectrum of mutation in various marker genes; but, to date, mutagenesis studies have not been...
