The possible mechanism of synchronization of NADH oscillations in yeasts were studied. It was shown that the synchronization time depends on cell concentration in suspension. Synchronization of oscillations after acetaldehyde addition was found in Saccharomyces сarlsbergensis whereas in S. сerevisiae oscillations were synchronized after adding potassium cyanide. It is possible, that synchronization of oscillations in S. сerevisiae requires low concentration of acetaldehyde and the high acetaldehyde concentration synchronizes oscillations in S. сarlsbergensis. In addition, a possible mechanism of synchronization by acetaldehyde in proposed.

Key words: yeast, NADH, synchronization, induction time.
