Abstract Asgard is a recently discovered archaeal superphylum, closely linked to the emergence of eukaryotes. Among archaea, Lokiarchaeota are abundant in marine sediments, but their situ activities largely unknown except for Candidatus ‘Prometheoarchaeum syntrophicum’. Here, we tracked activity incubations with Helgoland mud area sediments (North Sea) by stable isotope probing (SIP) organic polymers, 13C-labelled inorganic carbon, fermentation intermediates and proteins. Within active detected members class Loki-3, which appeared mixotrophically participate degradation lignin humic acids while assimilating CO2, or heterotrophically used lactate. In contrast, Loki-2 utilized protein degraded bacterial biomass formed incubations. Metagenomic analysis revealed pathways lactate degradation, involvement aromatic compound less globally distributed instead rely on degradation. We conclude that Lokiarchaeotal subgroups vary metabolic capabilities despite overlaps genomic equipment, suggest these occupy different ecologic niches sediments.

Abstract The roles of Asgard archaea in eukaryogenesis and marine biogeochemical cycles are well studied, yet their contributions soil ecosystems remain unknown. Of particular interest archaeal to methane cycling wetland soils. To investigate this, we reconstructed two complete genomes for soil-associated Atabeyarchaeia, a new lineage, genome Freyarchaeia, predicted metabolism situ. Metatranscriptomics reveals expression genes [NiFe]-hydrogenases, pyruvate oxidation carbon fixation via the Wood-Ljungdahl pathway. Also expressed encoding enzymes amino acid metabolism, anaerobic aldehyde oxidation, hydrogen peroxide detoxification carbohydrate breakdown acetate formate. Overall, include non-methanogenic acetogens, highlighting potential role terrestrial environments.

Archaea are diverse and ubiquitous prokaryotes present in both extreme moderate environments. Estuaries, serving as links between the land ocean, harbor numerous microbes that relatively highly active because of massive terrigenous input nutrients. account for a considerable portion estuarine microbial community. They play key roles biogeochemical cycles. Ammonia-oxidizing archaea (AOA) an abundant aquatic archaeal group estuaries, greatly contributing ammonia oxidation. Bathyarchaeota sediments, they may involve sedimentary organic matter degradation, acetogenesis, and, potentially, methane metabolism, based on genomics. Other groups also commonly detected estuaries worldwide. include Euryarchaeota, members DPANN Asgard archaea. Based biodiversity surveys 16S rRNA gene some functional genes, distribution abundance driven by physicochemical factors, such salinity oxygen concentration. Currently, increasing amount genomic information is becoming available advances sequencing technologies, especially AOA Bathyarchaeota, leading to better understanding their functions environmental adaptations. Here, we summarized current knowledge community composition major focusing Bathyarchaeota. We highlighted unique features potential adaptation strategies archaea, pointing out unknowns field scope future research.
