| Abstract: | The operational characterization of a fluidized-bed bioreactor for ethanol fermentation using Ca-alginate immobilized yeast cells is described. An additional air stream is supplied to the fermenter to ensure and maintain satisfactory fluidization behavior of beads and to avoid slug formation. The influence of physical properties such as bead density and liquid density on the fluidization quality and stability are discussed. |
