Photoinduced Carotenogenesis in Chlorotic Euglena gracilis.

abstract：:With an experimental system using mass spectrometry techniques and infra-red gas analysis of CO(2) developed for aquatic plants, we studied the responses to various light intensities and CO(2) concentrations of photosynthesis and O(2) uptake of the red macroalga Chondrus crispus S.
