Abstract
The effects of pH, temperature, and inoculum composition on Streptococcus thermophilus 404 and Lactobacillus bulgaricus 398 mixed cultures were studied. Linear quadratic models according to these three variables were proposed to express the growth and acidification characteristics, as well as the final proportion between the two strains. Initial and operating conditions, allowing maximization of these characteristics were determined. Finally, a graphic method to predict both final total concentration and final proportion of the two bacteria as a function of pH, temperature and inoculum composition is presented.
