Study of the distribution of autotrophic CO2 fixation cycles in Crenarchaeota [PDF]
Microbiology, 2010 Two new autotrophic carbon fixation cycles have been recently described in Crenarchaeota. The 3-hydroxypropionate/4-hydroxybutyrate cycle using acetyl-coenzyme A (CoA)/propionyl-CoA carboxylase as the carboxylating enzyme has been identified for (micro)aerobic members of the Sulfolobales. The dicarboxylate/4-hydroxybutyrate cycle using oxygen-sensitive

Distribution of Membrane Lipids of Planktonic Crenarchaeota in the Arabian Sea [PDF]
Applied and Environmental Microbiology, 2002 ABSTRACT Intact core tetraether membrane lipids of marine planktonic Crenarchaeota were quantified in water column-suspended particulate matter obtained from four depth intervals (∼70, 500, 1,000 and 1,500 m) at seven stations in the northwestern Arabian Sea to investigate the distribution of the organisms

Бюллетень Почвенного института им. В.В. Докучаева, 2015 Under study was the microbiome structure in virgin light-colored hydromorphized solonetz soil by using molecular-genetic and cultural methods. It was shown that the diversity of the microbial community is constantly decreasing down the soil profile being

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change
Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Diving deep into the origins of refractory dissolved amino acids in the ocean
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Abstract Amino acids are key constituents of marine peptides and proteins and are generally considered biologically labile or semi‐labile, yet their widespread occurrence throughout the ocean suggests bioresistance over extended timescales. To investigate this paradox, we conducted two parallel shipboard incubation experiments to track microbial ...

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.
