Scientists teach bacterium a new trick for artificial photosynthesis

Trainers of dogs, horses, and other animal performers take note: a bacterium named Moorella 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.
