Electroactive microorganisms markedly affect many environments in which they establish
outer-surface electrical contacts with other cells and minerals or reduce soluble extracellular …

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 …

OmcZ nanowires produced by Geobacter species have high electron conductivity (> 30 S
cm− 1). Of 111 cytochromes present in G. sulfurreducens, OmcZ is the only known nanowire …

Despite broad scientific interest in harnessing the power of Earth's microbiomes, knowledge
gaps hinder their efficient use for addressing urgent societal and environmental challenges …

Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Methane is a key compound in the global carbon cycle that influences both nutrient cycling
and the Earth's climate. A limited number of microorganisms control the flux of biologically …

Microbial consortia have been used in biotechnology processes, including fermentation,
waste treatment, and agriculture, for millennia. Today, synthetic biologists are increasingly …

Electrons can be transferred from microorganisms to multivalent metal ions that are
associated with minerals and vice versa. As the microbial cell envelope is neither physically …

Host-associated microbial communities have an important role in shaping the health and
fitness of plants and animals. Most studies have focused on the bacterial, fungal or viral …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …
