Endospore integrity and viability of Bacillus subtilis on simulated Martian regolith in rotational UVC radiation exposures
Gregory M Davis, Jonathan Horner, Andrew R. Greenhill…·Brad Carter
This study evaluates the viability and endospore formation of Bacillus subtilis on different Martian regolith simulants under UVC radiation exposure, finding that sulfur-rich regolith inhibits spore formation and that spores exposed to UVC show increased RecA gene expression.
