An Experimental Separation of Oxygen Liberation from Carbon Dioxide Fixation in Photosynthesis by Chlorella
Using intact cells of Chlorella pyrenoidosa it is possible to obtain oxygen by the reduction of certain reducible materials other than carbon dioxide. Of these, benzaldehyde was studied in some detail. This reduction does not involve the production of carbon dioxide from the benzaldehyde. Stoichiometrical relationships as expressed by the following equation: 2C(6)H(5)CHO + 2H(2)O --> 2C(6)H(5)C...
متن کاملEffect of Oxygen on the Light-enhanced Dark Carbon Dioxide Fixation in Chlorella Cells.
With Chlorella ellipsoidea cells, the effect of oxygen was investigated on the products of enhanced dark (14)CO(2) fixation immediately following preillumination in the absence of CO(2). When the reaction mixture was made aerobic by bubbling air (CO(2)-free) throughout preillumination and the following dark (14)CO(2) fixation periods, the initial fixation product was mainly 3-phosphoglyceric ac...
متن کاملPhotosynthesis in Rhodospirillum rubrum. I. Autotrophic carbon dioxide fixation.
The incorporation and distribution of activity from (14)CO(2) was investigated under autotrophic conditions in the facultative photoautotroph, Rhodospirillum rubrum, with cells cultured on hydrogen, carbon dioxide, and ammonium sulfate. In 1 second (14)CO(2) fixation experiments essentially all of the activity was found in 3-phosphoglyceric acid: plotted against time percent incorporation into ...
متن کاملPhotosynthesis in Rhodospirillum rubrum. II. Photoheterotrophic carbon dioxide fixation.
The contribution of the reductive pentose phosphate cycle to the photometabolism of carbon dioxide and to carbon metabolism in Rhodospirillum rubrum grown photoheterotrophically with l-malate as the carbon source is nil, unlike autotrophically grown R. rubrum. Glycolic acid appears to be the first stable product of CO(2) fixation in R. rubrum cultured photoheterotrophically on l-malate. The res...
متن کاملSeparation of Carbon Dioxide from Natural Gas by Matrimid-Based Mixed Matrix Membranes
Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...
