TL;DR: The diverse carbon fixation mechanisms that are found in archaea differ fundamentally from those of the well-known Calvin cycle, and their distribution mirrors the phylogenetic positions of the archaeal lineages and the needs of the ecological niches that they occupy.

Abstract: The acquisition of cellular carbon from inorganic carbon is a prerequisite for life and marked the transition from the inorganic to the organic world. Recent theories of the origins of life assume that chemo-evolution took place in a hot volcanic flow setting through a transition metal-catalysed, autocatalytic carbon fixation cycle. Many archaea live in volcanic habitats under such constraints, in high temperatures with only inorganic substances and often under anoxic conditions. In this Review, we describe the diverse carbon fixation mechanisms that are found in archaea. These reactions differ fundamentally from those of the well-known Calvin cycle, and their distribution mirrors the phylogenetic positions of the archaeal lineages and the needs of the ecological niches that they occupy.

CO2-Fixation Strategies in Energy Extremophiles: What Can We Learn From Acetogens?
TL;DR: This mini-review summarizes the current knowledge gathered on the CO2-fixation strategies among acetogens and applies the structural information obtained from hydrogenotrophic methanogens to highlight common features, as well as the specific differences of their CO2 -fixation systems.

TL;DR: A metagenomic study of the marine planktonic microbiota in which surface (mostly marine) water samples were analyzed as part of the Sorcerer II Global Ocean Sampling expedition, which yielded an extensive dataset consisting of 7.7 million sequencing reads.
Methanogenic archaea: ecologically relevant differences in energy conservation.
TL;DR: In methanogens with cytochromes, the first and last steps in methanogenesis from CO2 are coupled chemiosmotically, whereas in methenogens without cyto Chromes, these steps are energetically coupled by a cytoplasmic enzyme complex that mediates flavin-based electron bifurcation.

Archaeal dominance in the mesopelagic zone of the Pacific Ocean
TL;DR: A year-long study of the abundance of two specific archaeal groups (pelagic euryarchaeota and pelagic crenarchAEota) in one of the ocean's largest habitats suggests that most pelagic deep-sea microorganisms are metabolically active and the results suggest that the global oceans harbour approximately 1.3 × 1028Archaeal cells, and 3.1×10 28 bacterial cells.
