Abstract
The continuous ethanol production by free and Ca‐alginate‐entrapped cells of the yeast Saccharomyces cer. IBT H 191 was investigated in a membrane reactor and in a CSTR, respectively. An empiric productivity model for free‐cell fermentation was found to be valid for immobilized cells if no external diffusion resistance existed within the reactor. In such a case the fermentative power of the immobilized cells was identical with this one of the free cells. A change of the ethanol‐tolerance behaviour of the cells as a result of the cell‐immobilization did not occur.
