A biochemical framework for anaerobic oxidation of methane driven by Fe(III)-dependent respiration
Nature Communications, 2018 The unavailability of pure cultures has prevented a mechanistic understanding of anaerobic methanotrophy. Here the authors report a biochemical investigation of Methanosarcina acetivorans that supports a pathway anchored by Fe(III)-dependent mechanisms ...

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 ...

Insights into the NrpR regulon in Methanosarcina mazei Gö1
Archives of Microbiology, 2008 The methanogenic archaeon Methanosarcina mazei strain Gö1 contains two homologues of NrpR, the transcriptional repressor of nitrogen assimilation genes recently discovered and characterized in Methanococcus maripaludis. Insertion of a puromycin-resistance conferring cassette into MM1085 encoding a single NrpR domain with an N-terminal helix-turn-helix ...

Bioenergetics of methanogenesis from acetate by Methanosarcina barkeri [PDF]
Journal of Bacteriology, 1988 Methane formation from acetate by resting cells of Methanosarcina barkeri was accompanied by an increase in the intracellular ATP content from 0.9 to 4.0 nmol/mg of protein. Correspondingly, the proton motive force increased to a steady-state level of -120 mV.

Environmental Microbiology, Volume 28, Issue 4, April 2026.Moorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

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 ...

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

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

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.We tested whether anaerobic digesters could operate at lower temperatures without losing methane production. Pilot‐scale reactors were run at 48°C or 55°C. Methane yields and gas quality were similar. Lower temperatures reduced volatile fatty acids and supported more diverse microbial communities.
