View Full Version : Discussion: Microbes Use Hydrogen for Fuel in ...

2005-Jan-25, 06:12 PM
SUMMARY: A team of Colorado University researchers has uncovered bacteria that primarily use hydrogen as their fuel source in the colourful hot springs of Yellowstone National Park. Bacteria, such as salmonella, have been uncovered which use hydrogen for fuel before, but nobody expected this was happening in the intense heat of the hot springs. By using very sensitive detectors, they discovered that there's a constant supply of hydrogen being delivered to the bacteria from hydrothermal vents. Hydrogen is the most common element in the Universe, and finding bacteria that consumes it in extreme conditions further expands the places life could potentially gain a foothold.

now, wouldn't you want to seed jupiter or saturn with these microbes and dream about how life there would look like a billion years later.

probably just be a billion, trillion, septillon of those microbes :mellow:

TuTone, only if you're in a hurry.

I wonder, though if the high-temperature organizism of Yellowstone would like the cold. Maybe Venus would be a better target. I wonder though if the sulfur is a catalyst.

Like you two, I'm musing about life on Titan, breathing ammonia, drinking liquid methane, and carrying on in such very low temperatures. Hydrogen is probably their energy transfer agent as well. I haven't yet decided whether life in such an environment would move with all the deliberate speed of lichen or be comparatively quick.

If you imagine that water is only a transport medium and at the same time a limitation concerning tempertures (ex. hibernating polar insects)
Anything might be possible if methane or ethane can transport the right stuff.

All i have to say is keep making tools that will help find life.

im thinking any where there is a gentle flow of energy from one level to another ie oxidation and reduction
that has a reversable in some way from an outside energy
then there will eventually be some sort of life no matter how primitive
