Reviews and syntheses: Heterotrophic fixation of inorganic carbon – significant but invisible flux in environmental carbon cycling [PDF]
Biogeosciences, 2021 Heterotrophic CO2 fixation is a significant yet underappreciated CO2 flux in environmental carbon cycling. In contrast to photosynthesis and chemolithoautotrophy – the main recognized autotrophic CO2 fixation pathways – the importance of heterotrophic ...

Autotrophic carbon fixation pathways along the redox gradient in oxygen‐depleted oceanic waters
Environmental Microbiology Reports, 2020 Summary Anoxic marine zones (AMZs), also known as ‘oxygen‐deficient zones’, contribute to the loss of fixed nitrogen from the ocean by anaerobic microbial processes. While these microbial processes associated with the nitrogen cycle have been extensively

Fixation of Carbon Dioxide by Barley Roots [PDF]
Nature, 1952 THE uptake of carbon dioxide by plant root preparations has been demonstrated by various workers1–4. In addition to confirming the fact of fixation, I have investigated the effect of a number of factors involved and the compounds in which the absorbed carbon appears, using carbon-14.

Enhanced CO2 uptake of the coastal ocean is dominated by biological carbon fixation
Nature Climate ChangeObservational reconstructions indicate a contemporary increase in coastal ocean CO2 uptake. However, the mechanisms and their relative importance in driving this globally intensifying absorption remain unclear.

Heterotrophic Carbon Fixation in a Salamander-Alga Symbiosis
bioRxiv, 2020 The unique symbiosis between a vertebrate salamander, Ambystoma maculatum, and unicellular green alga, Oophila amblystomatis, involves multiple modes of interaction. These include an ectosymbiotic interaction where the alga colonizes the egg capsule, and

When green carbon plants meet synthetic biology
Modern Agriculture, 2023 Recycling carbon dioxide (CO2) into chemicals or fuels presents a promising avenue for mitigating carbon emissions and addressing the energy crisis. Plants serve as the ideal platform for the production of materials and chemicals, thanks to their innate ...

Study on Carbon Fixation Efficiency of Concrete Carbon Fixation Technology
Scientific Journal of TechnologyConcrete emits a large amount of carbon dioxide during the production process, exacerbating environmental problems such as greenhouse effect. However, at the same time, the hydration products of concrete (Ca(OH)2, C-S-H, etc.) can react with CO2 and have

Carbon dioxide fixation in trypanosomatids
Parasitology, 1975 Fixation of carbon dioxide has been demonstrated for extracts fromCrithidia fasciculata, Trypanosoma megaandTrypanosoma brucei bruceibloodstream and culture forms. The enzymes involved in this fixation were found to be ADP-stimulated phosphoenolpyruvate carboxykinase (E.C. 4. 1. 1. 32), ‘malic’ enzyme (E.C. 1. 1. 138–40) and pyruvate carboxylase (E. 0.

Diurnal variation in the coupling of photosynthetic electron transport and carbon fixation in iron-limited phytoplankton in the NE subarctic Pacific [PDF]
Biogeosciences, 2016 Active chlorophyll a fluorescence approaches, including fast repetition rate fluorometry (FRRF), have the potential to provide estimates of phytoplankton primary productivity at an unprecedented spatial and temporal resolution.
