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 chemoevolution 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…

Ecological investigations suggest that still more acetate-metabolizing species with novel properties await discovery, including anaerobic prokaryotes from the domains Bacteria and Archaea.
Opening the Black Box of Thermophilic Autotrophic Bacterial Diversity
Beyond the Calvin cycle: autotrophic carbon fixation in the ocean.
Recent discoveries in the field of autotrophic carbon fixation are reviewed, including the biochemistry and evolution of the different pathways, as well as their ecological relevance in various oceanic ecosystems.

Five alternative autotrophic pathways exist in prokaryotes that differ fundamentally from the Calvin-Benson cycle and reveal that the formation of an activated acetic acid from inorganic carbon represents the initial step toward metabolism.
Ammonia-oxidizing archaea use the most energy-efficient aerobic pathway for CO2 fixation
Significance CO2 fixation is the most important biosynthesis process on Earth, enabling autotrophic organisms to synthesize their entire biomass from inorganic carbon at the expense of energy
Archaea in biogeochemical cycles.
Sulfur-dependent archaea are confined mostly to hot environments, but metal leaching by acidophiles and reduction of sulfate by anaerobic, nonthermophilic methane oxidizers have a potential impact on the environment.
Distribution of CO2 fixation and acetate mineralization pathways in microorganisms from extremophilic anaerobic biotopes
This manuscript reviews the most commonly reported anaerobic organisms that fix carbon and mineralize acetate in extreme anoxic habitats and an inventory of autotrophic extremophiles by biotope is presented.

It is a consequence of this hypothesis that the postulated cycle cannot exist as a single isolated cycle but must be a member of a network of concatenated homologous cycles, from which all anabolic pathways appear to have sprung.
Autotrophic carbon dioxide fixation inAcidianus brierleyi
It is concluded that a modified 3-hydroxypropionate pathway operates in Acidianus brierleyi, a facultatively anaerobic thermoacidophilic archaebacterium, and that the reductive tricarboxylic acid cycle operates in this bacterium.
Methanogenic archaea: ecologically relevant differences in energy conservation
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.
Physiological Versatility of the Extremely Thermoacidophilic Archaeon Metallosphaera sedula Supported by Transcriptomic Analysis of Heterotrophic, Autotrophic, and Mixotrophic Growth
ABSTRACT Comparative transcriptomic analysis of autotrophic, heterotrophic, and mixotrophic growth of the archaeon Metallosphaera sedula (70°C, pH 2.0) revealed candidates for yet-to-be-confirmed
Mechanisms of CO2 fixation in bacterial photosynthesis studied by the carbon isotope fractionation technique
The results suggest that Chromatium and R. rubrum assimilate CO2 mainly via ribulose 1,5-diphosphate carboxylase and the associated reactions of the reductive pentose phosphate cycle, whereas Chlorobium utilizes other mechanisms.
Carbon Isotope Fractionation by Autotrophic Bacteria with Three Different C02 Fixation Pathways
Carbon isotope fractionation during autotrophic growth is studied in view of the different CO2 fixation reactions used by the bacteria and especially with regard to the isotopic composition of sedimentary carbon through time.
History of discovery of the first hyperthermophiles
The earliest archaeal phylogenetic lineage is represented by the extremely tiny members of the novel kingdom of Nanoarchaeota, representing the upper temperature border of life and found within high temperature environments.
