The invention relates to a microalgae culture system that provides a greater control of the culture due to distribution and the shape of its components, and the possibility to incorporate gases into the medium, resulting in an increased culture yield and lower energy consumption per volume unit. The invention comprises a pond (1) with a circular mantle, PVC parts and a removable lid. Each pond is provided with two aerators: one (12) placed over the liquid livel, adapted to introduce recirculated culture and air, and one shaped as a perforated semicicular pipe (16), placed in a lower position. The operation of both aerators achieves the movement of the culture liquid.
