Production Performance and Ameliorative Effects of Switchgrass on Severely Saline‐Alkali Land in Coastal Areas of China

GCB Bioenergy, Volume 18, Issue 6, June 2026.
Switchgrass cultivation sustained biomass production while rapidly improving soil structure and reducing salinity in coastal saline‐alkali soils. These changes reshaped microbial communities through environmental filtering, establishing plant‐soil‐microbe feedbacks that support both bioenergy production and ecological restoration.

The Methanosarcina barkeri genome: comparative analysis with Methanosarcina acetivorans and Methanosarcina mazei reveals extensive rearrangement within methanosarcinal genomes.

Journal of bacteriology, 2006
We report here a comparative analysis of the genome sequence of Methanosarcina barkeri with those of Methanosarcina acetivorans and Methanosarcina mazei. The genome of M. barkeri is distinguished by having an organization that is well conserved with respect to the other Methanosarcina spp.

Immunochemistry and localization of the enzyme disaggregatase in Methanosarcina mazei [PDF]

Journal of Bacteriology, 1993
The enzyme disaggregatase (Dag) from Methanosarcina mazei was studied immunochemically. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of purified Dag under reducing and nonreducing conditions revealed a single band with a 94-kDa molecular mass.

Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

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 ...

Facile Synthesis of H‐L‐Photo‐Lysine and Its Genetic Incorporation Into Proteins

ChemBioChem, Volume 27, Issue 10, 27 May 2026.
An efficient synthesis of a diazirine‐based noncanonical amino acid (ncAA), photo‐lysine (photoK), is reported, and its genetic incorporation into green fluorescent protein (GFP) is demonstrated. PhotoK‐enabled crosslinking is used to capture substrates and interaction partners of SIRT6 in vitro, in Escherichia coli, and in HEK293 cell lysates ...

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 ...

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...
