Hydrogen on the cheap.

Pharyngula points to this:

The hydrogenosome is a special organelle found in eukaryotic microbes as well as some fungi that like to live in poor oxygen environments.

In order to generate energy for the cell, it oxidizes pyruvate and releases hydrogen and produces ATP. Sound familiar? In fact, hydrogenosomes have an uncanny likeness to mitochondria--not only do both organelles produce ATP, but morphologically they are similar--they are both surrounded by a double membrane and they both compartmentalize their different metabolic functions.

The only big difference between the two is that hydrogenosomes use the anaerobic (fermentative) pathway while mitochondria use the aerobic pathway (Krebs cycle).


Some of us like to splice and dice genomes.

When asked whether there was any chance of putting a hydrogenosome in a blue-green algae (or maybe better a eukaryote algae?) and coupling photosynthesis to hydrogen generation- creating a commercially viable fuel source-producing recombinant, Syaffolee suggests a better alternative would be the cultivation of a naturally occuring green algae, Scenedesmus.

The significance of all this is that we don't need to burn fossil fuels to generate hydrogen fuels for automobiles or industry.

We could cultivate specific strains of algae that use photosynthesis to generate hydrogen on their own. Or engineer improvements in these microorganisms to get it on an industrial production line.

It means cheap energy to fuel industrial growth about as expensive as sunlight once the process is worked out.

That's why Bu$hCo wants to suppress science.

umm... any chance you'll ever say what any of this actually means?

My apologies.

See the amended post above, please.

Oh... OK. Cheap energy to fuel industrial growth sounds like something worth sinking some research dollars into. Thanks for the explanation in "science for dummies" terms. Has there been any estimate on development costs and return on investment? Even if ROI is 25 years it still might be worth it... Good post!
