Abstract<\/strong><\/span><\/p>\n

In this study, filtered and purified grape juice was fermented at 25\u2103, after the juice was inoculated with instant dry yeast Saccharomyces cerevisiae ATCC\u00ae 2601™ and the fermentation process took 10 days, a sample was taken every 24 hours to measure the total sugars concentration, biomass and ethanol concentration formed during fermentation. The initial conditions were set as follows: initial sugars concentration S_0=200 \u00b1 0.059g\/l, initial alcohol concentration P_0=0g\/l, initial yeast concentration X_0=1.5g\/l, it was observed that 12.66 \u00b1 0.071g of sugars were consumed after one day of fermentation to produce 10.52 \u00b1 0.22g of ethanol, which represents 83.10% of the consumed sugars, and the biomass increased by 0.66 \u00b1 0.273g, which represents 5.21% of the consumed sugars. The consumption of the substrate continues with the increase in the fermentation period, so that the total consumed sugars reached about 95.74% on the tenth day of fermentation, i.e. at a rate of 191.48 \u00b1 1.291 g, and the maximum alcohol concentration on the tenth day also reached 120.1 \u00b1 0.04g\/l. As for the biomass, the maximum concentration of biomass was X_max=15.39 \u00b1 0.04g\/l on the tenth day of fermentation, and the growth rate of yeast cells was \u03bc_max=0.674\/l. The process of biomass formation, substrate consumption, and alcohol production were modeled according to three special equations as a function of time, which were solved by Runge-Kutta and Euler methods, where the results of the solution by Euler method outperformed the results of the Runge-Kutta method in the measurements of biomass, substrate, and ethanol due to the low value of the coefficient of Determination R^2, the mean absolute error MAE, and the mean square error MSE, where the values reached:<\/span><\/p>\n
