abstract |
Microbes have multiple ways of producing energy. Which of these methods are possible
depends on the chemistry of the environment the microbes are in (e.g. not enough of
a metal or too much salt), with only specific methods working in certain environments.
The same would be true of any waters that might continue to exist on Mars. To narrow
down which methods of producing energy would be theoretically possible we simulated
martian waters using a collection of minerals that are chemically similar to the chemistry
measured by the Mars rover Curiosity in a crater on Mars. We added mud from an estuary
to the simulated martian water and identified which microbes were able to grow. We
then repeatedly transferred the growing microbes to fresh “martian” water to dilute
out the nutrients from the mud. Over time we observed that most of the microbes from
the mud have been lost but a few specific microbes were growing well. From this we
hope to investigate changes in the chemistry of the water that happen because of these
microbes, to try and identify specific chemistries that can be looked for by the future
rover missions on Mars seeking evidence of life. |
