Comparison of growth, acidification and productivity of pure and mixed cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus delbrueckii subsp bulgaricus 398
International audience; Pure and mixed controlled-pH batch cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus delbrueckii subsp. bulgaricus 398 have been conducted. The characteristics of growth and acidification and the productivity of the cultures were compared. During the mixed cultures, the growth characteristics revealed a pronounced stimulation of S. thermophilus whereas L. bulgaricus metabolism was not significantly improved. The final total population was 1.4 to 4.9 higher than in pure cultures. The acidification characteristics were not enhanced by the mixed culture conditions. The productivity of mixed cultures was 1.7 to 2.4 times higher as compared to…
