The fermentation of Kluveromycesfragitis on cheese whey was studied to assess the influence of temperature, pH, aeration rate, and lactose concentration on the biomass yield. The observations were analyzed statistically to determine the optimal operating conditions, A total of 17 experiments were conducted, 16 at the design points and 1 additional run to observe the growth of K.fragilis at the design's center point. The statistically significant factors were the temperature and lactose concentration. The optimal conditions for the growth of K.fragilis were: lactose concentration at 5%, temperature at 303 K, aeration rate at 2.0 vol/vol/min, and pH at 5,
