Introduction. The course of energy transformations in the processes of anaerobic fermentation refers to the indices of chemical energy as a result of biochemical reactions. This part of transformations is deeply studied and recognized, however, the synthesis of carbon dioxide in culture media is accompanied by the creation of energetic potentials in gas and liquid phases, is seriously understudied as of today. Materials and methods. The object of this research is the gas-liquid medium in the processes of anaerobic fermentation. Evaluation has been carried out for their energy potentials created on the basis of carbon dioxide synthesis. The theoretical study was carried out on the basis of the Henry's, Pascal and Archimedes laws. Results and discussion. Synthesized in anaerobic processes, carbon dioxide passes two stages of transformation. On the first stage, during the mass transfer between yeast cells and the medium, the concentration of CO2 increases to the saturation index in accordance with Henry's law, and on the second stage the formation of the dispersed gas phase is carried out. The endogenous process of carbon dioxide synthesis, the processes of saturation of the liquid phase and the formation of the dispersed phase are self-loading and those in which the corresponding energetic potentials are created, resulting in a circulating mixing of the media. In cases of using sealed fermentation vehicles, the gas phase is characterized by an appropriate energy potential due to the increased pressure. The levels of energy potentials of the compressed gas medium and dissolved CO2 are thermodynamically determinable and their ratios are interconnected due to the geometric volumes of the liquid and gas phases. The possibility of creating ocal zones of desaturation and saturation of the liquid phase in the total volume of the gas-liquid medium is shown. The presence of such zones means the possibility of regulatory influences on osmotic pressure and the removal of media from saturated and supersaturated states. Conclusions. The energy potential, associated with the saturation gradient of the media on CO2, provides a fast and continuous implementation of restoration in the saturation possibilities of the liquid phase and the activation of fermentation in the case of the saturation circuit restoration.
