Studies on Scenedesmus acutus growth. The incorporation of 14C‐glucose by Scenedesmus acutus under light and dark periods

Qualitative and quantitative estimations of alcohol-extractable compounds from (14)C-glucose-incorporated Scendesmus acutus cells were performed at various intervals of time. After two hours of incubation with (14)C-glucose in light, amino acids were synthesized at 65% and sucrose at 26% of the total input label. In the dark incorporation, 30% of the total radioactivity was found in amino acids and 46% in sucrose. Leucine and valine were detected only during the oxidation of glucose in light. The concentration of serine increased more in the presence of light, as compared to dark. These results on the oxidation of glucose are discussed in this article.
