摘要： A method is provided for optimally supplying autotrophic organisms with CO.sub.2 nutrient, the requirement for the nutrient fluctuating in dependence on growth and thus on the incident light, temperature and the density of the organisms. The pH in a culture channel containing the organisms is continuously measured and the introduction of CO.sub.2 into the culture channel is regulated in response to the measured pH. An arrangement is provided for practicing the method and comprises a channel in which a suspension of the organisms can be moved in one direction, at least one discharge means in the channel for introducing the CO.sub.2 gas into suspension, at least one control member connected to the discharge means for controlling the operation of the discharge means, at least one pH measuring means in the channel for immersion into the suspension, and a circuit connecting the pH measuring means and the control member to actuate the control member for introducing the CO.sub.2 in response to the pH measured by the pH measuring means.
