Microbiologists show that methanogenic archaea do not always need to form methane to survive. It is possible to bypass methanogenesis with the seemingly simpler and more environmentally friendly ...

Archaea are small single-celled microorganisms (microbes) that form one of the three domains of cellular life, along with bacteria and eukaryotes. They do not possess a nucleus and therefore belong to ...

Methanogenic archaea use sophisticated enzyme systems to live in energy-limited anoxic environments. A key mechanism for saving energy is electron bifurcation, a reaction that ‘splits’ the energy of a ...

A specialized enzyme machinery enables methanogenic microorganisms to thrive under extreme energy limitation. Methanogenic archaea use sophisticated enzyme systems to live in energy-limited anoxic ...

Oil hydrocarbons can be converted into methane through the process of methanogenic degradation which is typically orchestrated by a partnership of multiple microbes—both bacteria and methanogenic ...

We have developed a machine-learning approach to identify 3537 discrete orthologue protein sequence groups distributed across all available archaeal genomes. We show that treating these orthologue ...

The atmospheric levels of methane, which is known to be a potent greenhouse gas, have been steadily increasing for many years. Methanogenic archaea are a type of microbe that can generate methane as ...

The vast majority of methane, a potent greenhouse gas, released in the atmosphere is produced by a group of microorganisms called methanogens. Close relatives of methanogens, called anaerobic methane ...

Earth’s first life forms eventually took one of three different paths, forming the domains of Eukarya, Bacteria, and Archaea. These domains have been evolving separately for billions of years. Recent ...
