The Archaea are largely known as microorganisms thriving in extreme environments, but are in fact ubiquitouly found in nature. Importantly, archaeal methanogens are also stable members of the human gastrointestinal tract (GIT), where they […]

The outer membrane (OM) is an essential element in Gram-negative (diderm) bacteria. Its integrity is maintained by the control of lipids asymmetry via LPS and phospholipids transport by the Lpt and Mla systems, respectively. […]

Methanogenesis is an archaeal-specific metabolism that could have been active as early as 3.5 Gy ago with a direct impact on the evolution of the Earth’s climate system, as well as on current global […]

Methanogenic archaea are phylogenetically diverse, ancient and environmentally widespread. They are common inhabitants of the gastrointestinal tract of humans and other animals, and produce methane, a potent green-house gas, as a metabolic by-product. Despite […]

The bacterial envelope is one of the oldest and most essential cellular components, being involved in key housekeeping functions, such as physical integrity, cell division, motility, substrate uptake and secretion, and cell-cell communication. It […]

The Negativicutes are a poorly studied lineage of bacteria that include common inhabitants of the human oral and gut microbiome such as the anaerobe Veillonella, and which can also develop into opportunistic pathogens. Despite […]
