PHOTOBIOREACTOR FOR CULTIVATION OF MICROALGAE Russian patent published in 2021 - IPC A01G33/00 C12M3/00 C12M1/04 C12M1/36 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. A photobioreactor for the cultivation of microalgae is proposed. The photobioreactor contains a cylindrical container thermally insulated on the outside with loading and drain pipes, a lid with holes and a gas bubbler with a discharge pipe located at the bottom. A vertical transparent pipe is inserted through the lid into the container, and the specified pipe is plugged from below and above, and its upper part protruding from the container is provided with a suction pipe connected to the compressor inlet. The discharge pipe is brought out through the lid of the tank, connected by a pipeline to the compressor outlet. A smaller diameter pipe is coaxially placed inside the transparent pipe, and the protruding end of the smaller diameter pipe is open to the atmosphere, and red, blue and white LED strips are evenly fixed on its outer walls. A compressor, LED strips and a temperature sensor are connected to the control unit.

EFFECT: invention provides an increase in the rate of growth and division of microalgae.
