Summary
Some physiological data of cells of Pichia farinosa immobilized on sintered glass Raschig rings were compared with data from free cells. Glucose consumption and productivity of total polyols (arabitol, glycerol and erythritol) showed a simultaneous “inter-lag” phase. Enzymes that catalyse steps of the pentosephosphate pathway (glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, transaldolase and polyol dehydrogenase) showed a distinct increase after transfer of the cells into production medium. The activity of glycerol-3-phosphate dehydrogenase was generally low. Only alcohol dehydrogenase presented the inter-lag phase mentioned above.
