Abstract

The hardy spores of Bacillus species are well known for their resistance to unfavorable conditions such as UV and gamma radiation, hydrogen peroxide desiccation, chemical disinfection, or starvation. In particular, Bacillus pumilus strain SAFR-032 that was originally recovered from the Jet Propulsion Lab Spacecraft Assembly Facility has shown to exhibit unusually high resistance to UV radiation and peroxide treatment compared to other Bacillus species. To further understand the resistance of bacterial endospores to relevant outer space environments, spores of B. pumilus SAFR-032 were exposed for 1.5 years to selected parameters of space on board of the International Space Station (ISS). Here we are using a quantitative proteomics approach to gain insights into the resistance mechanism of B. pumilus.
