Carbon dioxide fixation by cell-free extracts of Aspergillus niger.
Aspergillus nz&r 72-4 ferments sucrose or glucose to citric acid in high yields when grown on a medium in which the trace metal content is closely controlled (1, 2). With the aid of glucose3,4-Cl4, Cleland and Johnson (3) showed that the glucose is cleaved to two 3-carbon fragments in a manner that is compatible with the Embden-Meyerhof scheme. The labeling in the citrate indicated that the cit...
متن کاملAmino acid stimulation of carbon dioxide fixation in cell-free extracts of Chlamydomonas reinhardtii.
In Chlamydomonas reinhardtii the synthesis of glutamate and aspartate during photosynthesis has been shown to be closely associated with the Krebs cycle (2). The addition of P-enolpyruvate but not pyruvate was found to enhance greatly the incorporation of "4CO2 in cell-free preparations of C. reinhardtii (3), suggesting that P-enolpyruvate carboxylase was important in CO2 fixation in this alga ...
متن کاملHeavy Carbon as a Tracer in Heterotrophic Carbon Dioxide Assimilation*
The first proof that heterotrophic, non-photosynthetic bacteria can fix carbon dioxide was presented in 1935 by Wood and Werkman (15). This investigation introduced the first experimental evidence that carbon dioxide serves as a building material in synthetic reactions of all forms of life, whether simple or complex. The synthesis of citric acid from oxalacetate by avian tissue was shown by Kre...
متن کاملAssimilation of carbon dioxide by hydrogen bacteria.
Autotrophic organisms can use carbon dioxide as their sole source of carbon. Within this group, the chemosynthetic bacteria secure energy for carbon dioxide assimilation by the oxidation of simple inorganic substances, although the photosynthetic organisms obtain this energy from light. The phylogenetic relationships of the chemosynthetic bacteria to the photosynthetic and to the heterotrophic ...
متن کاملCarbon Dioxide Fixation by Extracts of Streptococcus
sence of exogenously added glutamate and pyridoxal-5'-phosphate and produced radioactive aspartate in the presence of these components. Reduced nicotinamide adenine dinucleotide or reduced nicotinamide adenine dinucleotide phosphate could not be substituted for adenosine triphosphate (ATP); phosphoenolpyruvate even in the presence of nucleoside diphosphates could not replace pyruvate plus ATP; ...
