Resistance of Bacillus Endospores to Extreme Terrestrial and Extraterrestrial Environments
TLDR
The molecular laboratory model of spore resistance mechanisms is summarized and attempts to use the model as a basis for exploration of the resistance of spores to environmental extremes both on Earth and during postulated interplanetary transfer through space as a result of natural impact processes.
Natural Transfer of Viable Microbes in Space: 1. From Mars to Earth and Earth to Mars
The possibility and probability of natural transfer of viable microbes from Mars to Earth and Earth to Mars traveling in meteoroids during the first 0.5 Ga and the following 4 Ga are investigated,
Space Microbiology
TLDR
The data support the likelihood of interplanetary transfer of microorganisms within meteorites, the so-called lithopanspermia hypothesis.
Long-term survival of bacterial spores in space.
Protection of Bacterial Spores in Space, a Contribution to the Discussion on Panspermia
TLDR
The data suggest that in a scenario of interplanetary transfer of life, small rock ejecta of a few cm in diameter could be sufficiently large to protect bacterial spores against the intense insolation; however, micron-sized grains, as originally requested by Panspermia, may not provide sufficient protection for spores to survive.
Survival of rock-colonizing organisms after 1.5 years in outer space.
TLDR
Evidence is provided of the differential hardiness of cryptoendolithic communities in space, which some-but not all-of those most robust microbial communities from extremely hostile regions on Earth are also partially resistant to the even more hostile environment of outer space.
Systematic Study of Parameters Influencing the Action of Rose Bengal with Visible Light on Bacterial Cells: Comparison Between the Biological Effect and Singlet‐Oxygen Production
TLDR
Findings indicate that DNA is not the primary target, the inactivation of which leads to the killing of the authors' test organisms, and the cellular envelope appears to be the component being assaulted by the PDT.
A biosensor for environmental genotoxin screening based on an SOS lux assay in recombinant Escherichia coli cells
TLDR
Results indicate that the SOS lux test is potentially useful for the in situ and continuous detection of genotoxins.
