Expanding the Diet for DIET: Electron Donors Supporting Direct Interspecies Electron Transfer (DIET) in Defined Co-Cultures

Frontiers in Microbiology, 2016
Direct interspecies electron transfer (DIET) has been recognized as an alternative to interspecies H2 transfer as a mechanism for syntrophic growth, but previous studies on DIET with defined co-cultures have only documented DIET with ethanol as the ...

The Role of Active Site Residues in ATP Binding and Catalysis in the Methanosarcina thermophila Acetate Kinase

Life, 2015
Acetate kinase (ACK), which catalyzes the reversible phosphorylation of acetate by ATP, is a member of the acetate and sugar kinase/heat shock cognate/actin (ASKHA) superfamily. ASKHA family members share a common core fold that includes an ATPase domain

Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis

ChemistryEurope, Volume 4, Issue 4, April 2026.
Biotic‐abiotic photosynthetic systems integrate light‐harvesting semiconductors with nitrogenase's selective N2 reduction under ambient conditions, offering a sustainable alternative to conventional ammonia synthesis. Advancing rational interface design, efficient energy‐reaction coupling, and system integration is critical to realizing scalable, solar‐

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Methane-Linked Mechanisms of Electron Uptake from Cathodes by Methanosarcina barkeri

mBio, 2019
The Methanosarcinales, a lineage of cytochrome-containing methanogens, have recently been proposed to participate in direct extracellular electron transfer interactions within syntrophic communities.

Methanogenic cleavage of acetate by lysates of Methanosarcina barkeri [PDF]

Journal of Bacteriology, 1984
Cell lysates of acetate-grown Methanosarcina barkeri 227 were found to cleave acetate to CH4 and CO2. The aceticlastic reaction was identified by using radioactive methyl-labeled acetate. Cell lysates decarboxylated acetate in a nitrogen atmosphere, conserving the methyl group in methane.

Nitrite-reductase and peroxynitrite isomerization activities of Methanosarcina acetivorans protoglobin.

PLoS ONE, 2014
Within the globin superfamily, protoglobins (Pgb) belong phylogenetically to the same cluster of two-domain globin-coupled sensors and single-domain sensor globins. Multiple functional roles have been postulated for Methanosarcina acetivorans Pgb (Ma-Pgb)

Seasonal Composition and Structure of Methane-Cycling Communities in Alpine Lake Sediments of the Rila Mountains

Microorganisms
The global methane budget is largely driven by biogenic sources, many of which remain insufficiently characterized. Here, we investigated the community composition and seasonal dynamics of methanogenic and methanotrophic assemblages to elucidate the key ...

Uncovering the small proteome of Methanosarcina mazei using Ribo-seq and peptidomics under different nitrogen conditions

Nature Communications
The mesophilic methanogenic archaeal model organism Methanosarcina mazei strain Gö1 is crucial for climate and environmental research due to its ability to produce methane. Here, we establish a Ribo-seq protocol for M.
