“…The 3HP bi-cycle was first described in green, nonsulfur bacterium Chloroflexus aurantiacus ( 19 , 28 ) and since then has been commonly and exclusively attributed to the phylum Chloroflexota ( 29 , 30 ). However, enzymes for this pathway (e.g.…”

Carbon fixation pathways across the bacterial and archaeal tree of life

Carbon fixation is a critical process for our planet, however, its distribution across the bacterial and archaeal domains of life has not been comprehensively studied. Here, we performed an analysis of 52,515 metagenome-assembled genomes (MAGs) and discover carbon fixation pathways in 1007 bacteria and archaea. We reveal the genomic potential for carbon fixation through the reverse tricarboxylic acid cycle in previously unrecognised archaeal and bacterial phyla (ie. Thermoplasmatota and Elusimicrobiota) and show that the 3-hydroxypropionate bi-cycle is not, as previously thought, restricted to the phylum Chloroflexota. The data also substantially expands the phylogenetic breadth for autotrophy through the dicarboxylate/4-hydroxybutyrate cycle and the Calvin-Benson-Bassham cycle. Finally, the genomic potential for carbon fixation through the 4-hydroxybutyrate/3-hydroxypropionate cycle, previously exclusively found in Archaea, was also detected in the Bacteria. Carbon fixation appears thus to be much more widespread than previously known and this study lays the foundation to better understand the role of archaea and bacteria in global primary production and how they contribute to microbial carbon sinks.

“…Energy generation is based in the combustion of fossil fuels, which causes the artificial emission of CO 2 , promoting severe anthropogenic climate change [ 1 , 2 ] and several other consequences [ 3 , 4 , 5 ]. CO 2 in adequate quantities allows the planet to maintain a constant temperature.…”

“…Additionally, together with methane, they are considered the most important gases which cause greenhouse effects that contribute to global warming [ 6 ]. In order to reduce atmospheric CO 2 , new technologies have to be developed [ 2 , 7 ]. In nature, the capture and storage of CO 2 can occur through the formation of metal carbonates or carbon mineralization [ 8 ]; in this process, CO 2 is captured by inorganic salts containing magnesium or calcium, providing an inorganic carbonate which can usually be used in the construction industry [ 9 , 10 ].…”

Carbonate sequestration technology is a complement of CO2 sequestration technology, which might assure its long-term viability. In this work, in order to explore the interactions between Mn2+ ion with several ligands and carbonate ion, we reported a spectrophotometric equilibrium study of complexes of Mn2+ with pyrazine, quinoxaline or phenazine and its carbonate species at 298 K. For the complexes of manganese(II)–pyrazine, manganese(II)–quinoxaline and manganese(II)–phenazine, the formation constants obtained were log β110 = 4.6 ± 0.1, log β110 = 5.9 ± 0.1 and log β110 = 6.0 ± 0.1, respectively. The formation constants for the carbonated species manganese(II)–carbonate, manganese(II)–pyrazine–carbonate, manganese(II)–quinoxaline–carbonate and manganese(II)–phenazine–carbonate complexes were log β110 = 5.1 ± 0.1, log β110 = 9.8 ± 0.1, log β110 = 11.7 ± 0.1 and log β110 = 12.7 ± 0.1, respectively. Finally, the individual calculated electronic spectra and its distribution diagram of these species are also reported. The use of N-donor ligand with π-electron-attracting activity in a manganese(II) complex might increase its interaction with carbonate ions.

“…To combat the threat of climate change due to increasing levels of CO 2 in the atmosphere, researchers are exploring alternative production methods, which use CO 2 as an input, rather than an output [ 5 ]. Photosynthetic carbon fixation enables many proposed methods for Carbon Capture, Utilization, and Storage (CCUS) [ 6 ] by using atmospheric or emitted CO 2 as a building block to create products. CO 2 might be stored in products temporarily, as in biofuels, to replace fossil fuel emissions with a carbon neutral product, or could potentially be stored long-term, as in building materials, creating a net-negative drawdown of atmospheric CO 2 [ 7 ].…”
