Abstract
A mathematical model of a multistage bioreactor for continuous conversion of D-sorbitol to L-sorbose has been developed. The model solution presents possibility for determining the biomass concentration along the reactor height and the required number of stages for achievement of a given conversion rate. The mathematical model was tested on the basis of experimental data obtained in a laboratory glass reactor. The experimental conversion rate of D-sorbitol to L-sorbose rose to approximately 37% in the seconnd stage of the laboratory bioreactor. The value was in good agreement with the numerical results from the solution of the model. On the basis of these investigations it may be assumed that full conversion of D-sorbitol to L-sorbose should be obtained in bioreactor with 5-6 stages. © 1991 Taylor & Francis Group, LLC.
