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 …

Chloroflexi members are ubiquitous and have been extensively studied; however, the
evolution and metabolic pathways of Chloroflexi members have long been debated. In the …

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 …

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

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 …

Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur
compounds for use as electron donors in carbon dioxide fixation during anoxygenic …

This synthesis has three main parts. The first discusses the overall tree of life and nature of
the last common ancestor (cenancestor). I emphasize key steps in cellular evolution …

Photosynthetic bacteria are abundant in alkaline, terrestrial hot springs and there is a long
history of research on phototrophs in Yellowstone National Park (YNP). Hot springs provide …

Throughout geologic time, a strong feedback has existed between the geosphere and the
biosphere; therefore biological evolution and innovation can be linked to the evolution of …
