Abstract
Net inorganic carbon assimilation by Sargassum muticum was recorded in the light up to pH 9.9 and at pCO2 down to less than 5 p.p.m. Carbon uptake was measured on the basis of changes in the CO2 released by acid from 1-ml samples of the experimental seawater, and also calculated from pCO2, and pH according to standard tables. The pCO2 was monitored by infrared gas analysis. It was concluded that this alga assimilated HCO3− ion directly in photosynthesis.Keywords
