摘要：
The dairy industry today faces a problem of providing an alternative to adding sweeteners to fermented milk products in order to achieve the desired sweet taste without the added calories. Furthermore, it would be highly advantageous to establish a method for reducing lactose in fermented milk products to a level which is acceptable for lactose-intolerant consumers. The above problems have been solved by providing mutant Streptococcus thermophilus strains and mutant Lactobacillus delbrueckii subsp. bulgaricus strains that excrete glucose to the milk when the milk is inoculated and fermented with such Streptococcus thermophilus strains and Lactobacillus delbrueckii subsp, bulgaricus strains. Thus, the present invention relates to strains of Streptococcus thermophilus and Lactobacillus delbrueckii subsp, bulgaricus which secrete glucose to the milk substrate during fermentation, as well as to mixed cultures comprising the Streptococcus thermophilus strains and the Lactobacillus delbrueckii subsp, bulgaricus strains, starter cultures comprising the strains and dairy products manufactured with the cultures. The present method also relates to use of the strains for decreasing the lactose content of a fermented food product and for boosting growth of the probiotic BB-12®.La presente invención se refiere a la industria láctea enfrenta actualmente el problema de proveer una alternativa a la adición de edulcorantes a los productos de leche fermentada para lograr el sabor dulce deseado sin las calorías agregadas. Además, sería muy ventajoso establecer un método para reducir la lactosa en los productos de leche fermentada a un nivel que sea aceptable para los consumidores que tienen intolerancia a la lactosa. Los problemas arriba mencionados fueron solucionados proporcionando las cepas mutantes de Streptococcus therrrophilus y las cepas mutantes de Lactobacillus delbrueckii subespecie bulgaricus que excretan glucosa a la leche cuando la leche es inoculada y fermentada con tale
