Archaeal physiology

Archaeal physiology is the scientific study of the life-supporting functions and processes of Archaea, a domain of organisms that comprise single, nucleus-free cells, distinct from bacteria and eukaryotes.

    Eukaryotes evolved from a symbiosis involving Alphaproteobacteria and archaea phylogenetically nested within the Asgard clade. Two recent studies explore the metabolic capabilities of Asgard lineages, supporting refined symbiotic metabolic interactions that might have operated at the dawn of eukaryogenesis.

    Three recent metagenomic studies analyse methanogenesis-related genes in previously uncharacterized, sediment-inhabiting archaeal lineages. They elucidate the metabolic capacity encoded in the genomes of these lineages, yet how these organisms harness energy is still a mystery.

    Biofilms are a fundamental form of microbial life and occur in diverse environments, ranging from the mammalian gut to deep subsurface rocks. It is often claimed that most bacteria and archaea live in biofilms, but this claim awaits quantification. Recent updates on global microbial cell numbers prompt a revisiting of this question.
