Autotrophic CO2 fixation represents the most important biosynthetic process in biology.
Besides the well-known Calvin-Benson cycle, five other totally different autotrophic …

The fixation of inorganic carbon into organic material (autotrophy) is a prerequisite for life
and sets the starting point of biological evolution. In the extant biosphere the reductive …

Archaea of the phylum Thaumarchaeota are among the most abundant prokaryotes on Earth
and are widely distributed in marine, terrestrial, and geothermal environments. All studied …

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 …

Inorganic carbon fixation is essential to sustain life on Earth, and the reductive tricarboxylic
acid (rTCA) cycle is one of the most ancient carbon fixation metabolisms. A combination of …

Organisms capable of autotrophic metabolism assimilate inorganic carbon into organic
carbon. They form an integral part of ecosystems by making an otherwise unavailable form …

The cohort of the ammonia‐oxidizing archaea (AOA) of the phylum Thaumarchaeota is a
diverse, widespread and functionally important group of microorganisms in many …

Background Autotrophic carbon fixation is the primary route through which organic carbon
enters the biosphere, and it is a key step in the biogeochemical carbon cycle. The Calvin …

While the reductive pentose phosphate cycle is responsible for the fixation of most of the
carbon in the biosphere, it has several natural substitutes. In fact, due to the characterization …

Ammonia oxidation is an essential part of the global nitrogen cycling and was long thought
to be driven only by bacteria. Recent findings expanded this pathway also to the archaea …
