APPARATUS FOR CULTURING AUTOTROPHIC MICROORGANISMS Russian patent published in 2016 - IPC C12M1/04 C12N1/12 C12N1/20 

FIELD: biology.

SUBSTANCE: invention relates to cultivation of microorganisms. Device for culturing autotrophic microorganisms is disclosed. Apparatus comprises a cylindrical housing divided by horizontal partitions into sections for inlet and outlet of culture fluid and an additional section with inside mirror surface, pipes for inlet and outlet of cooling air, a film-forming device, an incandescent lamp, a bubbling device, a system for recirculation of culture fluid. System consists of a transparent circulation pipe located vertically along axis of symmetry of vehicle. Bubbling device with a mixture of carbon dioxide gas feed branch pipe with air is made in form of annular header in output of culture fluid, wherein inside central tube there is a shaft, circulation on shaft in zone of additional section is fixed rotary blower guide culture liquid from output of culture medium through circulation pipe in section of its input. Lower part of shaft is equipped with impeller made with possibility of rotation around its axis due to gas flow kinetic energy.

EFFECT: invention provides higher yield of biomass, higher quality, reduced dimensions of device, simplified design, reduced power consumption, optimum distribution of gas flow, higher quality of transfer.
