Engineered Bacteria Inhales CO2 and Produces Energy
Science & Tech / /
Similar to the way plants produce energy by converting water, sunlight and CO2 in it,this bacteria can do the same thing but 10 times more efficiently. Harvard Professor of energy, Daniel G. Nocera is the master mind behind this magnificent invention.
The bacteria absorbs hydrogen and carbon dioxide, and converts it into alcohol fuel. Professor Nocera has worked on this project with biologists from Harvard Medical School. Dedicated 18 months with their help to engineer bacteria called Ralston eutropha to consume hydrogen and CO2 and convert them into adenosine triphosphate (ATP).
These scientists based their research on some earlier discoveries made by Anthony Sinskey, a professor of microbiology at MIT, therefore they managed to insert more genes to the ATP into alcohol and cause the bacteria to excrete it.
Right now we`re making isopropanol, isobutanol, isopentanol
Nocera said in a lecture to the energy policy institute at chicago.
...these are all alcoholsyou can burn directly. And its coming from hydrogen from split water, and its breathing CO2. Thats what this bug is doing.
He named it Ralston Eutropha, it converts hyrogen and CO2 into adenosine triphosphate(ATP). by inserting certain genes to the bacteria, ATP is than converted to alcohol fuel.
The practical applications are unlimited. Its main goal is to help nature in cleansing our atmosphere from excess CO2, but Dr Nocera makes a point that this is only helping the process. Its not its solution.
With the results of the study soon to be published, Nocera is hoping to get more people excited about how it can continue to be applied for practical purposes.
He also pointed out that the process of depletition of our fossil fuels can be slowed down thanks to this bacteria. Alcohol fuels before Ralston Eutropha
were very expensive to be made and to be used as a substitute to conventional fuels.
This isn’t solving your CO2 problem. I’m taking CO2 out of the air, you burn it and you put the CO2 back. So it’s carbon neutral. I’m not going to reverse 400 ppm of CO2. But you’re not going to use any more stuff out of the ground.
Norcera has commented for Forbes.
