Microbially Accelerated Carbon Sequestration

[Jim Windle]

An interesting result, genetically modifying microbes to accelerate the formation of calcium carbonate from carbon dioxide in a subsurface environment.

Is anyone aware of other biogeochemical processes that have been accelerated or otherwise altered using genetically modified microbes?

Oh, and be sure to state your name so my cyborg can tell me who is calling!

algae engineered to pump fatty acids out of their cells seems like it
would be a winner, skim off the 'sequestrant', and throw it in the
diesel car's fuel tank

Nitrogen fixation.

Nitrogen alone is no greenhouse gas. But if the bacteria bind nitrous
oxides (which are 19-times more effecting in heating the Earth than
crabon dioxide!) this would help against global warming.



Anyway, in the more distant future we can't fix climate change only by
removing carbon from the air. Plants need a specific level of carbon
dioxide.
Better remove more effective greenhouse gasses, like methane, water
vapour, nitrous oxides, fluorcarbons (e.g. octafluorpropane), ....
