| Abstract: | Inducing yeast cells to self-flocculate as a cell immobilization method, the growth kinetics of the floes from Schizosaccharamyces pombe was studied in a experiment scale suspended-bed bioreactor using saccharified solution of starch. It was discovered that oxygen was a kind of limited substrates, and its effects on floc growth corresponded with Monod model. Further, a kinetic model described this floc growth was proposed. |
