Berkeley Lab | How to Train Your Bacterium
Trainers of dogs, horses, and other animal performers take note: a bacterium namedMoorella thermoacetica has been induced to perform only a single trick, but it’s a doozy. Berkeley Lab researchers are using M. thermoacetica to perform photosynthesis – despite being non-photosynthetic – and also to synthesize semiconductor nanoparticles in a hybrid artificial photosynthesis system for converting sunlight into valuable chemical products.
“We’ve demonstrated the first self-photosensitization of a non-photosynthetic bacterium, M. thermoacetica, with cadmium sulfide nanoparticles to produce acetic acid from carbon dioxide at efficiencies and yield that are comparable to or may even exceed the capabilities of natural photosynthesis,” says Peidong Yang, a chemist with Berkeley Lab’s Materials Sciences Division, who led this work.
“The bacteria/inorganic-semiconductor hybrid artificial photosynthesis system we’ve created is self-replicating through the bio-precipitation of cadmium sulfide nanoparticles, which serve as the light harvester to sustain cellular metabolism,” Yang says. “Demonstrating this cyborgian ability to self-augment the functionality of biological systems through inorganic chemistry opens up the integration of biotic and abiotic components for the next generation of advanced solar-to-chemical conversion technologies.”
