Biologist suggests carbon monoxide as an energy source for microbes on Mars

(Phys.org)--Gary King, a biologist at Louisiana State University has put forth the idea that if life did exist on Mars, it very possibly could have survived by using carbon monoxide. In his paper published in Proceedings of the National Academy of Sciences, he discusses his study of microbes in soil samples collected here on Earth that are able to pull in carbon monoxide and why it might relate to life on Mars.
