Natural carbon fixation and advances in synthetic engineering for redesigning and creating new fixation pathways

Journal of Advanced Research, 2023
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–Benson–Bassham pathway, which is predominantly found in plants, algae, and

Evolutionary temperature compensation of carbon fixation in marine phytoplankton [PDF]

Ecology Letters, 2020
The efficiency of carbon sequestration by the biological pump could decline in the coming decades because respiration tends to increase more with temperature than photosynthesis.

An ATP-sensitive phosphoketolase regulates carbon fixation in cyanobacteria. [PDF]

Nat Metab, 2023
Regulation of CO2 fixation in cyanobacteria is important both for the organism and global carbon balance. Here we show that phosphoketolase in Synechococcus elongatus PCC7942 (SeXPK) possesses a distinct ATP-sensing mechanism, where a drop in ATP level ...

Carbon content, carbon fixation yield and dissolved organic carbon release from diverse marine nitrifiers

bioRxiv, 2022
Nitrifying microorganisms, including ammonia-oxidizing archaea, ammonia-oxidizing bacteria and nitrite-oxidizing bacteria, are the most abundant chemoautotrophs in the ocean and play an important role in the global carbon cycle by fixing dissolved ...

Synergistic Potential of Contamination Remediation and Carbon Fixation: Functional Resilience of Carbon Fixation in Petroleum Hydrocarbon-Degrading Microbial Communities Under Enhanced Natural Attenuation [PDF]

Microorganisms
Enhanced Natural Attenuation (ENA) can accelerate pollutant degradation by adding electron acceptors or nutrients. However, its impact on carbon-fixing microorganisms, which are widely found in the natural attenuation process, remains unclear.

Augmenting the Calvin-Benson-Bassham cycle by a synthetic malyl-CoA-glycerate carbon fixation pathway. [PDF]

Nature Communications, 2018
The Calvin-Benson-Bassham (CBB) cycle is presumably evolved for optimal synthesis of C3 sugars, but not for the production of C2 metabolite acetyl-CoA.

DNA viral community enhances microbial carbon fixation capacity via auxiliary metabolic genes in contaminated soils [PDF]

Nature Communications
Soil is the largest organic matter repository on land and the virosphere is an essential component of soil carbon cycling. While a few carbon-related auxiliary metabolic genes (AMGs) in viruses are reported to potentially influence the hosts, the effects

Genetic Evidence for Two Carbon Fixation Pathways (the Calvin-Benson-Bassham Cycle and the Reverse Tricarboxylic Acid Cycle) in Symbiotic and Free-Living Bacteria

mSphere, 2019
Very few bacteria are able to fix carbon via both the reverse tricarboxylic acid (rTCA) and the Calvin-Benson-Bassham (CBB) cycles, such as symbiotic, sulfur-oxidizing bacteria that are the sole carbon source for the marine tubeworm Riftia pachyptila ...

6PPD-quinone affects the photosynthetic carbon fixation in cyanobacteria by extracting photosynthetic electrons [PDF]

The Innovation
Photosynthetic carbon fixation by cyanobacteria plays a pivotal role in the global carbon cycle but is threatened by environmental pollutants. To date, the impact of quinones, with electron shuttling properties, on cyanobacterial photosynthesis is ...
