  • Role of DNA protection and repair in resistance of bacillus subtilis spores to ultrahigh shock pressures simulating hypervelocity impacts

    Impact-induced ejections of rocks from planetary surfaces are frequent events in the early history of the terrestrial planets and have been considered as a possible first step in the potential interplanetary transfer of microorganisms. Spores of Bacillus subtilis were used as a model system to study the effects of a simulated impact-caused ejection on rock-colonizing microorganisms using a ...
