Postillumination CO2 fixation by wheat leaves
Photosynthesis Research, 1981Postillumination CO2 fixation by wheat leaves was studied following light-limited photosynthetic conditions. Dark CO2 fixation showed two phases differing by their rates of CO2 uptake and carbon metabolism. These two phases are related to preillumination light flux density.

CO2 Fixation in the Nervous Tissue
1971Publisher Summary This chapter explains CO 2 fixation in the nervous tissue. The primary CO 2 fixation reaction occurs at the oxaloacetate level. Both pyruvate carboxylase and phosphoenolpyruvate carboxykinase reactions lead to the formation of oxaloacetate, while the reaction of malic enzyme synthesizes malate.

Optimization strategies for CO2 biological fixation
Biotechnology AdvancesGlobal sustainable development faces a significant challenge in effectively utilizing CO2. Meanwhile, CO2 biological fixation offers a promising solution. CO2 has the highest oxidation state (+4 valence state), whereas typical multi‑carbon chemicals have lower valence states.

Photosynthetic CO2-Fixation Pathways
Annual Review of Plant Physiology, 1970The view has long been held that the Calvin cycle operates ubiquitously in higher plants, algae, and probably photoautotrophic bacteria, but there is now evidence for alternative pathways in some plants and bacteria. In the present article, particular emphasis will be placed upon the alternative pro cess in higher plants, but some aspects of current ...

Heterotrophic CO2 fixation by a bleached Euglena
Experimental Cell Research, 1966Abstract The distribution of carbon atoms from three carbon sources, bicarbonate, acetate, and succinate, has been determined in Euglena gracilis var bacillaris (streptomycin bleached) following 3 hr incubation. The distribution of carbon from bicarbonate is unaffected by the presence of acetate or succinate and is divided about equally between ...

Regulation of Photosynthetic CO2 Fixation
1981In any consideration of the rate and efficiency of nitrogen utilization by plants, it is obvious that attention must be paid to photosynthetic CO2 fixation. Photosynthetic CO2 fixation is both complementary to and competitive with nitrogen metabolism. Photosynthetic electron transport provides the energy for nitrogen metabolism, directly or indirectly;

Dark fixation of CO2 by flowers of cut roses
Planta, 1976Complete flower heads of cut roses (cv. Baccara) were exposed to (14)CO2 for 1-4 h. The flower tissue was able to fix CO2 via PEP carboxylase (E.C. 4.1.1.31) in the dark; various TCA products were identified in petals, ovary and anthers, including malate, aspartate, citrate, serine/glycine, glutamate and asparagine. The concentrations of these labelled

Breeding for Improved CO2 Fixation
1984Photosynthesis may be defined as the assimilation of CO2 by plants in light to form carbohydrates. The basic processes, which are probably similar in all plants, have been covered recently in a number of excellent reviews (1, 2, 3, 4, 5). Briefly, the starting point from a biophysical point of view is the excitation of a light harvesting pigment ...

Autotrophic CO2 fixation pathways in archaea (Crenarchaeota)
Archives of Microbiology, 2003Representative autotrophic and thermophilic archaeal species of different families of Crenarchaeota were examined for key enzymes of the known autotrophic CO(2) fixation pathways. Pyrobaculum islandicum ( Thermoproteaceae) contained key enzymes of the reductive citric acid cycle.
