[Macroscopic fluctuations in the alcohol dehydrogenase reaction]

When studying alcohol dehydrogenase reaction spontaneous oscillations of reaction rate were revealed. The value of these fluctuations essentially exceeded measuring error. The fluctuation amplitude had the maximum value when minimum buffer concentrations were used. Distribution of fluctuations according to their values was polymodal in all experiments. These oscillations seem to be classified as "macroscopic fluctuations" which have been revealed by S. Shnoll & coll [3].
