Nocera bacteria absorb CO2
This news has been reported by the American magazine Forbes. But, according to Nocera:
this bacteria does not solve the CO2 problems.
Soon, Daniel Nocera will publish all about his experiments in Science.
Since 2015, Nocera worked with biologists from Harvard Medical School to engineer a bacteria called Ralston eutropha to consume hydrogen and CO2 and convert them into adenosine triphosphate (ATP), the energy molecule used by natural organisms.
(…) Building on discoveries made earlier by Anthony Sinskey, a professor of microbiology at MIT, they inserted more genes to convert the ATP into alcohol and cause the bacteria to excrete it.
Nocera to his lecture to the Energy Policy Institute at Chicago:
Right now we’re making isopropanol, isobutanol and isopentanol. These are all alcohols you can burn directly. And it’s coming from hydrogen from split water, and it’s breathing in CO2. That’s what this bug’s doing.
This isn’t solving your CO2 problem,” he said. ”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.(…)
Daniel G. Nocera manages the ‘Nocera Lab‘ (‘the chemistry of renewable energy), at Harvard University.
The Nocera lab studies the basic mechanisms of energy conversion in biology and chemistry.
(…)We synthesize a variety of compounds and materials, ranging from organic supramolecular assemblies to inorganic coordination, organometallic, and extended layered compounds to biomolecules that permit us to investigate physical and chemical issues of pertinence to energy conversion.
Expertise in a host of steady-state (absorption, emission, Raman) and time-resolved (nanosecond, picosecond, femtosecond) laser spectroscopies and other physical methods permits us to define critical phenomena, which in turn guide us in the further design of new systems with targeted reactivity.(…)
