Study on Fermentation Kinetics of the Yeast Cells Immobilized in the Carriers of Ceramics
陶瓷载体固定化酵母发酵动力学研究

Spherical and rashig ring ceramics carrier were used to immobilize yeast cells to study the kinetics of their fermentation. The results showed that the kinetics constants of fermentation of the cells immobilized in the ceramics carrier were influenced by the diffusion inside and outside the carrier. The kinetics constants measured are for spherical carrier. Michaelis constant (K,) = 5.3g/L, maximum velocity (Vm) =0. 49g - (g - h)-1, inhibition constant of substrate (Kiss) =278g/L, maximum level of product resistance (Pm) =120g/L; for Rashig ring carrier; K, = 4. 1g/L, Vn = 0. 55g - (g -h)-1,Kis=320g/L,Pm = 140g/L.
