Problems solved by technology

However, the shear force in the existing draft tube airlift reactor still causes great damage to plant cells, and there is no solid surface on which cells can attach, which affects the growth of cells and the generation of metabolites
In addition, when using the existing airlift bioreactor to cultivate plant cells, the inoculation amount should not be too large, otherwise the cells will easily brown and even die due to insufficient oxygen supply

Abstract

The bioreactor includes main body, guide tube, external light sources and gas distributor. The main body is a circular or square transparent tube and with inoculating port, air outlet and liquid replenishing port in the upper wall and air inlet in the lower wall; the guide tube is fixed inside the main body with some interval to the upper and the lower wall of the main body; the gas distributor is communicated with the air inlet; and the external light sources are arranged around the main body. It features that the guide tube made of metal screen is set in the center of the main body and the gas distributor is below the guide tube. Inside the bioreactor, plant cells are attached to the screen to grow with reduced airflow shearing force. The bioreactor is suitable for large scale growth of plant cell and has the advantages of simple structure and convenient operation.
