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 […]

The Archaea represent an understudied but important fraction of microbial diversity present in a wide variety of environments and ecosystems, including the human body. They have key ecological roles and a unique place in […]

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 quality of multiple sequence alignments plays an important role in the accuracy of phylogenetic inference. It has been shown that removing ambiguously aligned regions, but also other sources of bias such as highly […]
