A method for cultivation of photosynthetic micro-organisms such as micro-algae, photobacteria, and similar organisms, through circulation within tubes made of transparent plastic material of the suspension of said organisms in an appropriate culture medium, envisages: carrying out agitation/mixing of said suspension in the culture medium in said tubes in a pulsed and non-continuous way; separating the biomass produced from the culture medium by means of sifting with a system of differential-inclination sieves; introducing C02 with total dissolution thereof inside the tubes in which the suspension of said micro-organisms in their own culture medium circulates, introducing also buffer solutions in said culture medium; extracting the oxygen produced in the photosynthesis in a natural way by means of skimmers distributed along the tubes traversed by the culture medium; controlling the temperature inside the tubes in order not to reach temperatures that are harmful to the growth of the photosynthetic micro-organisms by modifying the concentration of the biomass in the culture medium by means of said system of sieves so as to increase the transparency of the culture medium and reduce the solar energy absorbed. |
