Cyborg Bacteria Change the Game in Carbon Dioxide Reduction

Researchers at the University of California Berkeley may have introduced a new era in artificial photosynthesis. They’ve devised a way to cover bacteria with cadmium sulfide semiconductor nanocrystals to breakdown carbon dioxide (CO2 ) into acetic acid, a precursor to a host of other products. In research that is being presented at the 254th National Meeting & Exposition of the American Chemical Society (ACS), Kelsey K. Sakimoto, a researcher at the lab of Peidong Yang at Berkeley , has demonstrated that the non-photosynthetic bacterium known as moorella thermoacetica can self-assemble into nanocrystal-clad cyborgs that essentially supercharge the bacteria into CO2 -reduction powerhouses. “It's actually a natural, overlooked feature of their biology,” explains Sakimoto in an e-mail interview with IEEE Spectrum . “This bacterium has a detoxification pathway, meaning if it e...
