Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VII. The Assimilation of Carbon Dioxide by Molds.

des Sciences Math6matiques," tome 1, volume 1, page 601, it is added that J. Perott used the term sulerien groups for abelian groups in American Journal of Mathematics, 11, 99 (1889). This matter is somewhat complicated by the fact that C. Jordan used the term abelian group, with a somewhat different meaning from that now commonly assigned to it, in his widely used "Trait6 des substitutions" (1...

Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VI. On the Possibility of Carbon Dioxide Reduction via the Carboxylase System.

Recent experiments,' carried out with the aid of labeled carbon, have shown beyond any doubt that CO2 enters into the metabolism of a large variety of organisms in the absence of light. As a consequence it has been suggested that CO2 assimilation may be a process of wide-spread occurrence in living systems. The metabolic processes of living organisms are for the most part enzyme catalyzed. The ...

Assimilation 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 ...

Heavy 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...
