Halophilic archaea produce wax esters and use an alternative fatty acyl-coenzyme A reductase for precursor synthesis Open
Wax esters (WE) are fatty acid-based neutral lipids thought to be restricted to bacteria and eukaryotes, playing a key role in the functioning and maintenance of cells, especially under adverse conditions. Here, we show that several haloph…

Sporadic distribution of a new archaeal genetic code with all TAG codons as pyrrolysine Open
Numerous genetic codes developed during the evolution of Eukaryotes and three are known in Bacteria, yet no alternative genetic code has been established for Archaea. Some bacterial and archaeal proteins include selenocysteine or pyrrolysi…

Stable coexistence between an archaeal virus and the dominant methanogen of the human gut Open
The human gut virome, which is mainly composed of bacteriophages, also includes viruses infecting archaea, yet their role remains poorly understood due to lack of isolates. Here, we characterize a temperate archaeal virus (MSTV1) infecting…

Nature AND Nurture: Enabling formate-dependent growth in<i>Methanosarcina acetivorans</i> Open
Methanogenic archaea are crucial in global carbon cycling as around 1 Gt of the potent greenhouse gas, methane, is produced annually. Major contributors belong to the order Methanosarcinales, which contain some of the most versatile methan…

Anaerobic hexadecane degradation by a thermophilic Hadarchaeon from Guaymas Basin Open
Hadarchaeota inhabit subsurface and hydrothermally heated environments, but previous to this study, they had not been cultured. Based on metagenome-assembled genomes, most Hadarchaeota are heterotrophs that grow on sugars and amino acids, …

Methanomethylophilus alvi gen. nov., sp. nov., a Novel Hydrogenotrophic Methyl-Reducing Methanogenic Archaea of the Order Methanomassiliicoccales Isolated from the Human Gut and Proposal of the Novel Family Methanomethylophilaceae fam. nov. Open
The methanogenic strain Mx-05T was isolated from the human fecal microbiome. A phylogenetic analysis based on the 16S rRNA gene and protein marker genes indicated that the strain is affiliated with the order Methanomassiliicoccales. It sha…

Metagenomics uncovers dietary adaptations for chitin digestion in the gut microbiota of convergent myrmecophagous mammals Open
In mammals, myrmecophagy (ant and termite consumption) represents a striking example of dietary convergence. This trait evolved independently at least five times in placentals with myrmecophagous species comprising aardvarks, anteaters, so…
