    • 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®.
    • 今天的乳制品行业面临的问题是为发酵乳制品添加甜味剂提供替代方案,以达到所需的甜味,而不会增加热量。 此外,建立将发酵乳制品中的乳糖还原至乳糖不耐受消费者可接受的水平的方法将是非常有利的。 上述问题已经通过提供突变体嗜热链球菌菌株和突变体德氏乳杆菌(Lactobacillus delbrueckii subsp。)来解决。 当牛奶被接种并用这种嗜热链球菌菌株和德氏乳杆菌(Lactobacillus delbrueckii subsp),保加利亚乳杆菌(Lactobacillus delbrueckii subsp)保护中的菌株发酵时,保加利亚乳杆菌将葡萄糖排泄到牛奶中。 因此,本发明涉及嗜热链球菌和德氏乳酸杆菌亚种(Streptococcus delbrueckii subsp)保加利亚乳杆菌菌株,其在发酵期间将葡萄糖分泌至乳底物,以及包含嗜热链球菌菌株和德尔布莱克酵母亚种保加利亚乳杆菌菌株的混合培养物,其包含 用培养物制造的菌株和乳制品。 本方法还涉及菌株用于降低发酵食品的乳糖含量和促进益生菌BB-12的生长。
