Hydrogen-Emitting Microbe Examined
Concerned Onlooker wrote to mention an article at Science Daily discussing a microbe that lives in volcanic environments, which emits Hydrogen gas as a waste product. "As the world increasingly considers hydrogen as a potential biofuel, technology could benefit from having the genomes of such microbes. 'C. hydrogenoformans is one of the fastest-growing microbes that can convert water and carbon monoxide to hydrogen," remarks TIGR evolutionary biologist Jonathan Eisen, senior author of the PLoS Genetics study. "So if you're interested in making clean fuels, this microbe makes an excellent starting point.'"
Nope, they can't coexist (at least not function together.) This bacteria requires an anoxic environment, while the algae will release oxygen as a byproduct of photosynthysis.
That said, I really don't think we can think of chemotrophs (organisms that survive by converting one chemical to another) as a very good energy source. Recreating their environment and feedstocks on an industrial scale would be very energy intensive. In the case of the bacteria in the article, even gathering and purifying the carbon monoxide from emissions of hydrocarbon burning energy plants would be quite energy inefficient. You can probably just forget about collecting the carbon monoxide from a car's tailpipe; it would be a total waste of energy.
I'll never make that mistake again, reading the experts' opinions. - Feynman
When you read the article they have these things that look like explanatory hyperlinks to words like 'water', 'research' and 'scientists', but are, instead, commercials tied to the words. What is this called? Whatever it's called, it's VERY IRRITATING. And I wish Slashdot would not use submissions based on web pages that do this. When I am tricked into an advertisement this way I feel like I've crawled into bed with someone who suprises you with both male and female sex organs. It just doesn't seem right to be surprised like that.
