carbon fixation

The process by which carbon from the atmosphere is converted into carbon compounds, such as carbohydrates, in plants and algae, usually by photosynthesis.

The major purpose of this study was to assess the strategies for carbon fixation of the common reed (Phragmitesaustralis) in littoral habitats of flood plain lakes and ponds by using stable isotope natural abundances.
It is recognised that nonbiological methods for using electricity for carbon fixation (assimilating carbon from CO2 into organic compounds, such as biofuels) are starting to match and even exceed microbes' abilities.
De Beers Group is focused on maximising the benefits that can be generated for the wider mining community and is partnering with the academic community on the research so the research insights are retained by the academic partners Greg Dipple, project lead and professor at the Bradshaw Research Initiative for Minerals and Mining (BRIMM) at UBC, said: "We've demonstrated rapid carbon fixation within days to weeks in the lab, but the challenge is to reproduce this success at large volumes.
An enzyme called Rubisco is key to the process of converting atmospheric carbon into an organic compound the plant consumes, a process known as ''carbon fixation.''
Marine phytoplankton, like coccolithophores, are responsible for 50 percent of global carbon fixation. (1) Through photosynthesis, which also produces oxygen as a by-product, they fix carbon dioxide throughout their lives in the surface waters of the ocean.
The [8] Carbon Fixation ($139.99) from Buck Rub Gear is sure to draw some attention this year.
obliquus, carried out every 24 hours for 7 days, were used as a proxy for carbon fixation. The biomass yields of the untreated control and of the treatments were similar (maximum yield 2.9, 3.1, and 3.9 g [L.sup.-1] for the control, 500 ppm, and 1000 ppm treatment, respectively), suggesting that neither the sulphur nor the ash had an inhibitory effect on algal growth.
In terms of carbon fixation, the inferred higher plant growth rate in H pastures was probably offset by longer plant residence time in L pastures.
A bio-fuel contains energy from geologically recent carbon fixation and is produced from living organisms.
Genes detected for carbon fixation were generally similar across the soils examined, except for 10F and 1F fields, which both had a lower percentage of genes from this category.
Their cells possess cell walls, as plant cells do, but the structural material is subtly different, as is their mode of nutrition which is heterotrophic--that is, they don't rely on direct photosynthesis for their carbon fixation and synthesis of organic material.
