Changes in concentrations of coenzyme F420 analogs during batch growth of Methanosarcina barkeri and Methanosarcina mazei [PDF]

Applied and Environmental Microbiology, 1989
Coenzyme F420 has been assayed by high-performance liquid chromatography with fluorimetric detection; this permits quantification of individual coenzyme F420 analogs whilst avoiding the inclusion of interfering material. The total intracellular coenzyme F420 content of Methanosarcina barkeri MS cultivated on methanol and on H2-CO2 and of Methanosarcina

Comparative Physiology and Genomics of Thermincola and Carboxydocella Strains and Description of Two Novel Isolates

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Two novel thermophilic bacteria, Thermincola strain AZ34E and Carboxydocella strain AZ29I, were isolated from hydrothermal environments and shown to oxidise carbon monoxide via the water‐gas shift reaction. Comparative genomic and phylogenetic analyses revealed that all currently described isolates within Thermincola and Carboxydocella each represent a

A Proteasome from the Methanogenic Archaeon Methanosarcina thermophila [PDF]

Journal of Biological Chemistry, 1995
A 645-kDa proteasome was purified from Methanosarcina thermophila which had chymotrypsin-like and peptidylglutamyl-peptide hydrolase activities and contained alpha (24-kDa) and beta (22-kDa) subunits. Processing of both subunits was suggested by comparison of N-terminal sequences with the sequences deduced from the alpha- and beta-encoding genes (psmA ...

Increasing sulfate levels show a differential impact on synthetic communities comprising different methanogens and a sulfate reducer [PDF]

, 2019
Methane producing microbial communities are of ecological and biotechnological interest. Syntrophic interactions among sulphate reducers and aceto/hydrogenotrophic and obligate hydrogenotrophic methanogens form a key component of these communities, yet ...

Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Anaerobic co-digestion of acetate-rich with lignin-rich wastewater and the effect of hydrotalcite addition [PDF]

, 2016
The methane potential and biodegradability of different ratios of acetate and lignin-rich effluents from a neutral sulfite semi-chemical (NSSC) pulp mill were investigated.

Genetic Encoding of a Trifunctional Photo‐Cross‐Linker with a Cleavable Alkyl Ester Moiety

ChemBioChem, Volume 27, Issue 3, 12 February 2026.
A novel noncanonical amino acid, DiZAAsu, possessing photo‐cross‐linking, biotinylation, and alkaline‐cleavable functionalities, is genetically encoded by an engineered pyrrolyl‐tRNA synthetase mutant. The alkyl ester moiety expands the design space of cleavable photo‐cross‐linkable amino acids.
