Open AccessA non-methanogenic archaeon within the order Methanocellales
Serpentinization, a geochemical process found on modern and ancient Earth, provides an ultra-reducing environment that can support microbial methanogenesis and acetogenesis. Several groups of archaea, such as ...

Open AccessNon-autotrophic methanogens dominate in anaerobic digesters
Anaerobic digesters are man-made habitats for fermentative and methanogenic microbes, and are characterized by extremely high concentrations of organics. However, little is known about how microbes adapt to su...

Open AccessMicrobial metabolic networks in a complex electrogenic biofilm recovered from a stimulus-induced metatranscriptomics approach
Microorganisms almost always exist as mixed communities in nature. While the significance of microbial community activities is well appreciated, a thorough understanding about how microbial communities respond...

Open AccessPhysiological and genomic features of highly alkaliphilic hydrogen-utilizing Betaproteobacteria from a continental serpentinizing site
Serpentinization, or the aqueous alteration of ultramafic rocks, results in challenging environments for life in continental sites due to the combination of extremely high pH, low salinity and lack of obvious ...

A novel metatranscriptomic approach to identify gene expression dynamics during extracellular electron transfer
Microbial respiration via extracellular electron transfer (EET) is a ubiquitous reaction that occurs throughout anoxic environments and is a driving force behind global biogeochemical cycling of metals. Here w...
