Abstract
Four different strains ofLactobacillus delbrueckii subsp.bulgaricus (Ss1 and Yop12) andStreptococcus salivarius subsp.thermophilus (Ss2 and Yop9) were isolated from two different yogurt sources in Argentina. In medium containing different carbon sources: lactose, fructose, sucrose or glucose plus fructose, the growth of a mixed culture (Yop12+Ss2) shows stimulation ofS. thermophilus and inhibition ofL. bulgaricus with respect to pure cultures. Both microorganisms in mixed culture grew less well on glucose plus galactose. However, in medium with glucose or galactose, both microorganisms were stimulated.
