Choroplast Pigments of Deuterated Green Algae


IT has recently been found that green algae can be successfully grown in 99.6 per cent deuterium oxide1. Algae such as Chlorella vulgaris and Scenedesmus obliquus adapted to deuterium oxide thus provide a source of highly deuterated organic compounds. Since the organisms grow in deuterium oxide with carbon dioxide as the sole carbon source, the cells must be equipped for photosynthetic activity even though their organic matter is constructed with deuterium in place of hydrogen.
