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 metabolism of Archaea, the third domain of life, resembles in its complexity those of
Bacteria and lower Eukarya. However, this metabolic complexity in Archaea is accompanied …

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 …

Ammonia-oxidizing archaea (AOA) are among the most abundant microorganisms and key
players in the global nitrogen and carbon cycles. They share a common energy metabolism …

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 …

Despite an increased understanding of functions in sponge microbiomes, the interactions
among the symbionts and between symbionts and host are not well characterized. Here we …

Chromate (Cr (VI)), as one of ubiquitous contaminants in groundwater, has posed a major
threat to public health and ecological environment. Although various electron donors (eg …
