The given investigation is devoted to the study of the rate of clot formation of modern fermented product - yoghurt. The composition of this product includes microorganisms of two types: Lactobacillus bulgaricus and Streptococcus thermophilus. These organisms split monosaccharides with the formation of lactic acid according to the homofermentative mechanism. It is proposed that the electric and magnetic field with frequency of 2,45gHz is used as the activating action. The activation of microorganisms has been carried out with the direct action of microwaves. The analytical control has been conducted according to the well-known standard methods. The investigation results have been discussed and the idea of accelerating the active transport by means of possible accumulation of additional energy in ATF system has been suggested: the additional energy obtained is spent for the active transport of nutrients and water through the membrane with the help of proteins-carriers. The acceleration mechanism of the second passive type of substance transfer has been suggested which is necessary for the life of microorganisms. It has been stated that the time duration of the technological cycle of yoghurt has been reduced by 25%.
