In natural anoxic environments, anoxygenic photosynthetic bacteria fix CO2 by
photoheterotrophy, photoautotrophy, or syntrophic anaerobic photosynthesis. Here, we …

Microbial phototrophs, key primary producers on Earth, use H2O, H2, H2S and other
reduced inorganic compounds as electron donors. Here we describe a form of metabolism …

A key goal of synthetic biology is to engineer organisms that can use solar energy to convert
CO2 to biomass, chemicals, and fuels. We engineered a light-dependent electron transfer …

Microbial rhodopsin, a significant contributor to sustaining life through light harvesting, holds
untapped potential for carbon fixation. Here, we construct an artificial photosynthesis system …

A promising approach for the synthesis of high value reduced compounds is to couple
bacteria to the cathode of an electrochemical cell, with delivery of electrons from the …

Solar-driven bioelectrosynthesis represents a promising approach for converting abundant
resources into value-added chemicals with renewable energy. Microorganisms powered by …

The direct conversion of CO2 to value-added chemical commodities, thereby storing solar
energy, offers a promising option for alleviating both the current energy crisis and global …

Oxidation–reduction reactions underlie energy generation in nearly all life forms. Although
most organisms use soluble oxidants and reductants, some microbes can access solid …

Direct interspecies electron transfer (DIET) between microbial species prevails in some key
microbial consortia. However, the electron transfer mechanism (s) in these consortia is …

A hybrid approach combining water-splitting electrochemistry and H2-oxidizing, CO2-fixing
microorganisms offers a viable solution for producing value-added chemicals from sunlight …
