Enhancing CO₂ fixation by synergistic substrate cofeeding
The irrevocable rise of atmospheric CO₂ levels has prompted the development of scalable carbon fixation technologies in recent years. To this end, biological non-photosynthetic methods serve as promising leads since they not only sequester CO₂, but also convert it into a variety of value-added …

Vegetation and microbial determinants of soil carbon isotopic composition
… processes such as mineralization and dark CO₂-fixation by microbes and roots contribute significantly to the δ¹³C signature of bulk soil at depth, one cannot simply determine whether the δ¹³C value of the soil at depth is indicative of a past vegetation assemblies (i.e. C₃/C₄ transitions); …

Transcriptional profiling and flux measurements of polyhydroxybutyrate production in Synechocystis
(cont.) to determine the CO₂ uptake rates and PHB production rates of strains engineered for enhanced CO₂ fixation and PHB production respectively.

Antioxidant responses of pea (Pisum sativum L.) protoplasts
… the polarographic estimation of photosynthesis, CO₂-dependent O₂ evolution did not decrease. At sulfite concentrations of 3.0 mM or less, light-dependent O₂ evolution increased and was probably due to a concomitant SO₂-dependent O₂ evolution. Photosynthesis determined as ¹⁴CO₂ fixation was not …

Structure-Function Studies on Two Phosphoenolpyruvate Carboxylases
… carboxylase (Pepc) are two important CO₂-fixation enzymes which share a similar reaction mechanism. Both operate through a lid-gated active site and have a hypothesized enol-pyruvate intermediate in their catalytic pathway. While PEPCK is an important metabolic enzyme in animals and …

Metabolic bases for the differential response of 'Kwangkyo' and 'Hood' soybean (Glycine max (L.) Merr) to the herbicide paraquat
… Paraquat at 1 μM or higher inhibited rapidly the CO₂ fixation capacity of leaf mesophyll cells, isolated enzymatically from both cultivars. This result shows that the differential response does not result from any differences at the site of paraquat action in chloroplast membranes.

Molecular Analysis of Type IV Pilus Assembly in Clostridium perfringens
… in semi-defined medium and an atmosphere without CO₂. The grew well in nutrient-rich media with or without CO₂ in the atmosphere, although elimination of glucose resulted in decreased production of acetate, propionate, and butyrate. The results suggest a role for Cpb in anaplerotic CO₂ fixation …

Studies on the mechanisms of action of the herbicide safener CGA- 92194
… for their effects on CO₂ fixation, protein, DNA, RNA and lipid syntheses of enzymatically isolated leaf cells of soybean [<u>Clycine max</u> (L.) Merr]. At physiological concentrations of less than 10 μM, CGA-92194, cyometrinil and flurazole were stimulatory of all …

Sulfite reductase and thioredoxin in oxidative stress responses of methanogenic archaea
… that utilize simple compounds such as H₂ + CO₂, acetate and methanol for the production of methane, an end-product of their metabolism. These obligate anaerobes belonging to the archaeal domain inhabit diverse anoxic environments such as rice paddy fields, human guts, rumen of ruminants, and …

Metal-cyclam based Metal-Organic Frameworks for CO₂ Chemical Transformations
Designing new materials for CO₂ capture and utilization is one of the most challenging research topics. Metal-organic frameworks (MOFs) are one of the most efficient CO₂ adsorbents, as well as an emerging class of heterogeneous catalysts for CO₂ chemical transformations. Highlighted by their high …
