Methods for cultivating photosynthetic microorganisms are described. The method includes the steps of injecting a liquid culture medium into a photosynthetic reactor according to a controlled flow rate, injecting a gas into the reactor according to a controlled flow rate through a gas injector of the reactor so that the gas injected through the gas injector moves up to as far as the exhaust by circulating in the reaction pipe, in a direction of circulation from the low end to as far as the high end of the reaction pipe, circulating the liquid culture medium with the circulation device, and controlling the circulation device and the gas injector in order to establish in at least one substantially horizontal reaction section of the reaction pipe gas/liquid two-phase flow conditions of the laminated flow or slug flow or elongated bubble flow type.
