Abstract

To investigate the modulation of OA-responses by light intensity, cells of E. huxleyi strain RCC 1216 were acclimated to ambient and high pCO2 (380 vs. 1000 µatm) under limiting and saturating light intensities (50 vs. 300 µmol photons m-2 s-1). Growth rates and cellular quotas of POC and PIC were measured. Photosynthetic O2 evolution was measured as a function of light and of [DIC].
