Magnetically assisted bioreactors directly control the motion of magnetic bio-supports by assisting magnetic field,which improves mass transfer and relative motion between catalyst particles and can be combined with the advantages of fixed-bed,slurry-bed,moving-bed and fluidized-bed reactors. In this paper,magnetic bio-supports are characterized from three aspects,including magnetic material,carrier material and construction method;basic principles for construction of axial/transverse electromagnetic field and permanent magnetic field are summarized;configurations of magnetically assisted stirred reactor,magnetically assisted fixed-bed,magnetically assisted fluidized-bed and magnetically stabilized fluidized-bed reactor as well as their applications in biological and chemical processing are presented. Finally,research of magnetically assisted bioreactor is still in the laboratory, and further development asks for novel bio-compatible magnetic supports,controllable homogeneous large-scale assisted magnetic field and more creative reactor design.
