Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Electrotrophy, the growth of microbes on extracellular electron donors, drives important
biogeochemical cycles and has practical applications. Studies of Fe (II)-based electrotrophy …

Iron is a micronutrient for nearly all life on Earth. It can be used as an electron donor and
electron acceptor by iron-oxidizing and iron-reducing microorganisms and is used in a …

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

Rhodopseudomonas palustris is an attractive option for biotechnical applications and
industrial engineering due to its metabolic versatility and its ability to catabolize a wide …

Photosynthetic organisms have evolved versatile electron transport chains that efficiently
convert solar energy into chemical energy. Researchers can engineer these electron …

Microbial biofilms are ubiquitous. In marine and freshwater ecosystems, microbe–mineral
interactions sustain biogeochemical cycles, while biofilms found on plants and animals can …

Microbes exchange electrons with their extracellular environment via direct or indirect
means. This exchange is bidirectional and supports essential microbial oxidation–reduction …

Sporomusa ovata is a bacterium that can accept electrons from cathodes to drive microbial
electrosynthesis (MES) of acetate from carbon dioxide. It is the biocatalyst with the highest …

Anthropogenic carbon dioxide (CO2) release in the atmosphere from fossil fuel combustion
has inspired scientists to study CO2 to biofuel conversion. Oxygenic phototrophs such as …
