In a hot spring on the Russian volcanic island of Kunashir, there lives a particular type of microbe which consumes poisonous carbon monoxide as nourishment, and exhales hydrogen. The microbe is called C. hydrogenoformans, and researchers at the The Institute for Genomic Research recently finished analyzing its complete genome sequence.
One day, the carbon monoxide waste from other industries may be used to feed vats of these microbes, and the resulting hydrogen could be collected and used to power the fuel cells of tomorrow.
