The direct conversion of starch hydrolysate (15 Dextrose Equivalent) to ethanol using a coimmobilizate of amyloglucosidase and Saccharomyces cerevisiae was studied in a batch stirred tank reactor. The performance of the reactor for various system parameters viz. stirrer speed, pH, initial substrate concentration and temperature has been studied. The ethanol productivity is limited by inhibition for initial substrate concentrations above 75 g/l. The optimum pH and temperature of reaction is 5.0 and 30 °C respectively. © 1992 Springer-Verlag.

The transient state analysis of the consecutive sequence of reactions S → P1 → P2 taking place inside a porous spherical coimmobilized biocatalyst is discussed for the case in which each step follows Michaelis Menten type kinetics. The theoretical analysis includes intraparticle diffusional limitations. The model equations are solved by the explicit finite difference method. The effect of various parameters of importance on the batch reactor performance is discussed. Comparison of the model with experimental results has been shown. © 1994 Springer-Verlag.
