An international team of microbiologists from the Medical University of Graz, the DSMZ—German Collection of Microorganisms ...

an important fuel for other sediment-dwelling organisms such as methanogens (which include marine archaea) and heterotrophic bacteria. The products of these organisms feed back into the carbon cycle ...

This study represents the first successful cultivation of ultrasmall bacteria that parasitize archaea ... and other biochemical characteristics. The bacterium was observed to have a limited ...

While previous research had described bidirectional promoters in eukaryotes, as well as in a few bacteria and archaea species, the new study establishes divergent transcription—the reading of genes in ...

Indeed, archaea and bacteria appear very similar biologically (members of both groups consist of tiny cells without much internal structure) and different from eukaryotes. However, until ...

physiological and evolutionary characteristics. Bacteria form one of the three domains of life; the others are archaea and eukaryotes. Bacterial species and their habitats exhibit great diversity.

Archaea—one of the three primary domains of life alongside Bacteria and Eukaryota—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet, ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus.

After further searches, microbiologists identified the corresponding organisms, described them, and classified them as a separate archaeal subgroup called Asgard archaea. Like bacteria ...
