Comparison of glycolytic NADH oscillations in yeasts Saccharomyces cerevisiae and Saccharomyces carlsbergensis.
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 carlsbergensis whereas in S. cerevisiae oscillations were synchronized after adding potassium cyanide. It is possible, that synchronization of oscillations in S. cerevisiae requires low concentration of acetaldehyde and the high acetaldehyde concentration synchronizes oscillations in S. carlsbergensis. In addition, a possible mechanism of synchronization by acetaldehyde in proposed.
