By an integrated factorial experiment, optimal proportions of the quantity of inoculation yeast [Saccharomyces cerevisiae], molasses dosage and degree of initial dilution were established for periodic yeast cultivation. An equation describing the process was derived. This equation makes it possible to assess yeast yield at any value of the above parameters within their extreme limits. Yeast cultivation under optimized conditions results in a 25% increase of the economic coefficient of reproduction as compared with the control, thus approximating the theoretically conceivable value.
