Abstract
Comparison of the production of L‐phenylacetylcarbinol (L‐PAC) from benzaldehyde by cells of Torulaspora delbrueckii immobilized in calcium alginate and barium alginate showed that cells immobilized in calcium alginate beads were usable for up to six cycles compared with nine cycles for barium alginate‐immobilized cells. Barium alginate‐immobilized cells yielded a total of 2.17 g of L‐PAC in nine cycles whereas in the case of calcium alginate‐immobilized cells, a total of 1.17 g of L‐PAC was formed when 400 mg benzaldehyde and 400 mm^3^ of acetaldehyde were used in each cycle as substrate and co‐substrate respectively.
