Myronenko National University of Food Technologies Key words: ABSTRACT Gas-liquid medium Alcohol Carbon dioxide Energy potential Solubility Circulating circuit The article concerns to the estimation of energy poten- tials of gas-liquid media. Such potentials are represented by the aggregate of the chemical energy of dissolved sugars in the conditions of anaerobic fermentation processes, which are culminated with the formation of ethyl alcohol and carbon dioxide with the release of free energy in 230 kJ/mole of fermented glucose. From the last 169 kJ it is transformed into heat energy, which should be removed from the culture medium, and 61 kJ is used by yeast cells. The self-propelled formation of dissolved carbon dioxide with the subsequent synthesis of the dispersed gas phase leads to the initiation of the circulating circuits of the gas-liquid mixture amplified by the effects of thermal circulation circuits. The presence and continuous renewal of the dispersed gas phase indicates the presence of the potential for the formation of the phase- surface, and the presence of the gas-retaining ability of the system means a certain level of potential energy of a swollen gas-liquid medium. For anaerobic fermentation, the gas-holding ability is de- termined by a combination of two sources, namely the for- ced introduction the dispersed mass of air into the medium and synthesized carbon dioxide in a medium. Thus, internal microbiological transformations lead to the formation of flows of thermal energy, material flows of C 2 N 5 OH and CO 2 , the kinetic energy of circulating circuits, the potential energy of dissolved carbon dioxide and swollen media. In addition, under the influence of hydrostatic pressure, a gradient of saturation level of the liquid phase on СО 2 is formed, which completes by the additional driving factor of the circulating circuits. The physical basis of the potentials of dissolved gases in the form of manifestations of the presence of a gravi- tational field and Henry’s law is shown, mathematical for- malizations are proposed in the estimations of the energy potentials of soluble gases and the possibilities of inten- sification of mass transfer processes due to their release in ripple regimes.
