Researchers at The Institute for Genomic Research (TIGR) have sequenced the genome of Carboxydothermus hydrogenoformans, an extremophile bacteria that lives in a Russian volcano, eating carbon monoxide and producing hydrogen and CO2 as waste. Biological production of hydrogen is one of the candidates for how a fuel cell economy would be supported, so getting this sequence will help us better understand how hydrogen-forming bacteria do their voodoo.
Rather than give the full scientific breakdown of the research, I'll just point you to Mike Millikin's post at Green Car Congress.
so what is the enviromental impact on global warming and CO2 output. How would one handle the CO2 waste.
The Russian bacteria the most useful bacteria in the world. =)
