Abstract
An infrared CO2 analyzer was used to measure production and assimilation of CO2 by 11 marine or freshwater algae in acidic media. Considerable differences among the algae were found in the concentration of CO2 required to saturate photosynthesis and in the compensation concentration of CO2. High compensation values were always lowered by lowering the O2 concentration, even to concentrations which did not reduce respiration in the dark. It was concluded that respiration was inhibited during photosynthesis. In four of the algae, respiration was replaced by a different process of CO2 production during photosynthesis.
