A device for growing microorganism cultures, is new. A device for growing microorganism cultures, is new. The device comprises: (a) a reaction tank provided with at least one supply of nutrients; (b) means for dispersion and removal of gas; and (c) a cone-shaped internal conduit, extending towards the top of tank and provided with at least one entry opening close to its bottom end and at least one exit opening close to its upper end, with a heat source situated in this conduit or at least partially under its entry opening, with the surface of exit opening being smaller than that of entry opening and smaller than lateral surface of cylinder whose bases are, respectively, formed by entry opening of conduit and its projection onto the base of reaction tank. The entry opening of cone-shaped conduit may be in its large base and its exit opening is situated close to its smaller base. The gas dispersion means are situated in lower part of reaction tank, outside cone-shaped conduit and in the zones of tank not lying below the entry opening of cone-shaped conduit but close to the outer sides of it. The upper end of the cone-shaped conduit is joined to a vertical conduit extending outside reaction tank after traversing nutrient supply tank and serving as gas exit. Nutrient supply tank is joined to nutrient supply connector. At least one part of a vertical conduit starting from the upper end of cone-shaped conduit is made of thermoconductive material. The reaction tank is also provided with means of water supply and at least one exit pipe for the mixture of water and microorganisms, running from the lower part of reaction tank, preferably from the point below the entry opening of cone-shaped conduit.
