fluidized bed and a liquid-liquid droplet spray column. Another objective was to identify the conditions for which this new type of bioreactor would perform superior to a conventional bioreactor. Outline In Chapter 2, the fluidization behavior of different types of gel beads is presented for a 2-phase liquid-fluidized bed. However, a conventional fluidized bed bioreactor (FBB) operating under high perfusion velocity is incapable of providing the desired performance due to the resulting damage to cell-containing microcapsules and large void volume. In this study, we developed a novel diversion-type microcapsule-suspension fluidized bed bioreactor (DMFBB).

Fluidized-bed bioreactors are necessarily immobilized-cell reactors. A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

 · The fluidized-bed bioreactor (FBBR) is an application of the LS fluidized bed. These bioreactors can be run in a single or double column system, depending on the treatment process being carried out. The FBBR is an attached-growth process. The microbes attach to the fluidized media and form a biofilm on the surface . A liquid-fluidized bed or packed bed with gel beads is attractive as an immobilized-cell bioreactor. The performance of such bioreactors is influenced by the physical behavior of these beads.

Thus the great filtration of a fluidized bed sump. Another myth is that the fluidized bed K1 media needs to have several weeks of submersion before it can form a biofilm which weights it down and allow it to circulate in the sump. In truth there will be small bubbles in the K1 media when it is first put into the sump.  · fluidized bed bioreactor In this system, care must be taken to avoid the destruction and decomposition of immobilized enzymes. The particle size of immobilized enzymes is an important factor for the formation of a smooth fluidized bed.
