The bioreactor - for the production of cultures of photosynthetic microorganisms or plant cells dispersed in nutrient-containing aqueous solutions - comprises reaction tubes (31) that are essentially transparent to solar radiation and lie at a shallow angle, generally of between 2 DEG and 6 DEG , to the horizontal, between two collectors (35, 43) at different levels; a nozzle (36A, 36B) is provided at the lower end of each tube (31) to blow in air (or the like) in an alternating manner as a propellant to carry the culture upwards and to remove toxic gases generated by the photoreactions; some of the tubes (31), acting alternately, return the culture from the upper collector (43) to the lower collector (35); the in-blown gas and the gas produced by the culture is removed or optionally recovered from the upper collector (43). |
