Desulfovibrio baarsii is a sulfate reducing bacterium, which can grown on formate plus sulfate as sole energy source and formate and CO2 as sole carbon sources. It is shown by 14C labelling studies that more than 60% of the cell carbon is derived from CO2 and the rest from formate. The cells thus grow autotrophically. Labelling studies with [14C]acetate, 14CO and [14C]formate indicate that CO2 fixation does not proceed via the Calvin cycle. The labelling patterns of alanine, aspartate… 
Carbon assimilation pathways in sulfate-reducing bacteria II. Enzymes of a reductive citric acid cycle in the autotrophic Desulfobacter hydrogenophilus
TLDR
The data indicate that in D. hydrogenophilus a reductive citric acid cycle is operating in autotrophic CO2 fixation, and since other autotrophic sulfate reducers possess an acetyl CoA pathway for CO2fixing, two different autOTrophic pathways occur in the same physiological group.
Oxidative and reductive acetyl CoA/carbon monoxide dehydrogenase pathway in Desulfobacterium autotrophicum
TLDR
It is shown that the physiological cosubstrate in this bacterium is not tetrahydrofolic acid, but a tetrahYDropterin containing 4 mol of l-glutamate per mol of pterin, and substantiates the proposal that the former pathway is operating in the reductive direction for CO2 fixation into acetyl CoA, and in the oxidative direction for acetylCoA oxidation to CO2.
Acetate oxidation to CO2 in anaerobic bacteria via a novel pathway not involving reactions of the citric acid cycle
TLDR
The findings suggest that in the investigated sulfate-reducers acetate is oxidized to CO2 via C1 intermediates, which provides a possible explanation for the reported different fluoroacetate sensitivity of acetate oxidation by anaerobic bacteria, for mini-methane formation, as well as for the postulatedAnaerobic methane oxidation by special sulfates.
Microbial growth on carbon monoxide
TLDR
The utilization of carbon monoxide as energy and/or carbon source by different physiological groups of bacteria is described and compared and the little information available on the nutritional and physicochemical requirements determining the sink strength is summarized.
Autotrophic synthesis of activated acetic acid from two CO2 in Methanobacterium thermoautotrophicum
TLDR
These experiments indicate that a corrinoid is involved in acetate synthesis and probably not in methanogenesis from CO2; the metal is light-reversibly alkylated and functions in methyl transfer to the acetate methyl.
Acetate oxidation to CO2 via a citric acid cycle involving an ATP-citrate lyase: a mechanism for the synthesis of ATP via substrate level phosphorylation in Desulfobacter postgatei growing on acetate and sulfate
TLDR
It is shown that the enzyme mediating citrate formation is an ATP-citrate lyase (EC 4.1.3.8) rather than a citrate synthase, which enables D. postgatei to couple the oxidation of acetate to 2 CO2 with the net synthesis of ATP via substrate level phosphorylation.
The reductive glycine pathway allows autotrophic growth of Desulfovibrio desulfuricans
TLDR
Genomic, transcriptomic, proteomic and metabolomic analyses reveal that D. desulfuricans assimilates CO2 via the reductive glycine pathway, a seventh CO2 fixation pathway, which is reflected in the dependence of the autotrophic growth rate on the ammonia concentration.
Lithoautotrophic growth of sulfate-reducing bacteria, and description of Desulfobacterium autotrophicum gen. nov., sp. nov.
TLDR
Carbon autotrophy was evident from comparative growth experiments with non-autotrophic, acetate-requiring species, from high cell densities ruling out a cell synthesis from organic impurities in the mineral media, and by demonstrating that 96–99% of the cell carbon was derived from 14C-labelled CO2.
Carbon isotopic heterogeneity of coenzyme F430 and membrane lipids in methane‐oxidizing archaea
TLDR
The data support the interpretation that ANME in marine sediments at methane seeps assimilate both methane and DIC, and the carbon isotopic compositions of the tetrapyrrole coenzyme F430 and the membrane lipids archaeol and hydroxy-archaeol reflect their relative proportions of carbon from these substrates.
Oxidative and reductive acetyl CoA/carbon monoxide dehydrogenase pathway in Desulfobacterium autotrophicum
It has been proposed that in some anaerobic facultatively autotrophic bacteria the acetyl CoA/CO dehydrogenase pathway is operating both in the reductive and in the oxidative direction, depending on

Acetate and carbon dioxide assimilation by Desulfovibrio vulgaris (Marburg), growing on hydrogen and sulfate as sole energy source
TLDR
Findings indicate that in Desulfovibrio vulgaris (Marburg) pyruvate is formed via reductive carboxylation of acetyl-CoA, oxaloacetate via carboxyation of pyruVate or phosphoenol pyruviate, and α-ketoglutarate from oxalo acetate plus acetyl -CoA via citrate and isocitrate.

TLDR
Data showed that acetyl CoA is the central intermediate for biosynthesis and excluded the operation of the Calvin cycle in A. woodii.

All reactions of the proposed reductive tricarboxylic acid cycle could be demonstrated in autotrophically growing cells.
Acetyl CoA, a central intermediate of autotrophic CO2 fixation in Methanobacterium thermoautotrophicum
TLDR
The finding that pyruvate was not incorporated into compounds derived from acetyl CoA, whereas acetate was incorporated into derivatives of acetylCoA and pyruVate in a 1:1 ratio demonstrates that pyrupvate is synthesized by reductive carboxylation of acety CoA.
One-Carbon Metabolism in Methanogens: Evidence for Synthesis of a Two-Carbon Cellular Intermediate and Unification of Catabolism and Anabolism in Methanosarcina barkeri
TLDR
One-carbon metabolic transformations associated with cell carbon synthesis and methanogenesis were analyzed by long- and short-term ( 14)CH(3)OH or (14)CO(2) incorporation studies during growth and by cell suspensions and it was not possible to distinguish between acetate and acetyl coenzyme A as the immediate product of two-carbon synthesis with the methods employed.

TLDR
These experiments indicate that a corrinoid is involved in acetate synthesis and probably not in methanogenesis from CO2; the metal is light-reversibly alkylated and functions in methyl transfer to the acetate methyl.
Role of Carbon Dioxide and Acetate in Biosynthesis by Sulphate-reducing Bacteria
TLDR
This work has shown that the principal sulphate reducer, Desulphovibrio desulphuricans, in pure culture, can only use for this purpose the hydrogen of formate, isobutanol, lactate, pyruvate and ethanol, which are oxidized during the reduction of sulphate to carbon dioxide, butyrate and acetate as the case may be.
Anaerobic acetate oxidation to CO2 by Desulfobacter postgatei
TLDR
The order of magnitude of the observed enzyme activities was sufficient to account for an oxidation of acetate via the citric acid cycle and for a synthesis of oxaloacetate from acetate and CO2 as anaplerotic reaction.
