Initially, most plant cell culture reactors used microbial reactors. Because the morphological structure of plant cells is different from that of microbial cells, plant cells are larger than microbial cells, have poor tolerance to shear force and have much lower requirements for oxygen than microorganisms, so microbial reactors are not completely suitable for the growth and production of plant cells. Many plant cell culture reactors different from traditional microbial reactors have appeared and are constantly improving. The reactors used for plant cell culture mainly include stirred reactors, non-stirred reactors and their improved reactors, as well as plant cell immobilization reactors and membrane reactors.
