EXPLORATORY STUDIES ON THE PHYSIOLOGY AND ECOLOGY OF A PSYCHROPHILIC MARINE DIATOM 1
SUMMARY The effect of light, of 2 wavelengths, and of 3 temperatures on the uptake and evolution of O 2 by the antarctic marine diatom , Fragilaria sublinearis, has been examined with mass spectrometry. The responses of this organism to light, in terms of O 2 exchange, were qualitatively similar to...

Summary: | SUMMARY The effect of light, of 2 wavelengths, and of 3 temperatures on the uptake and evolution of O 2 by the antarctic marine diatom , Fragilaria sublinearis, has been examined with mass spectrometry. The responses of this organism to light, in terms of O 2 exchange, were qualitatively similar to those recorded by Hoch et al. with the blue‐green Anacystis nidulans. In addition, distinctive temperature optima were indicated for O 2 , production and uptake, which help to explain the psychrophilic character of the diatom. The possibility of varying rates of O 2 uptake in the light being associated with photoassimilation of organic substrates has been discussed. |
