摘要:
The challenge for the dairy industry is to add sweeteners to fermented dairy products in order to achieve the ideal sweetness without adding calories. In addition, it would be very beneficial to develop a method to reduce the lactose content of fermented milk products to a level acceptable to lactose intolerant consumers. The above problems were solved by providing variety strains.Mutants of Streptococcus macularis and mutants of calcium lactate strain delbrucki subsp. Bulgaricus, which excretes glucose into milk in a safe and fermented condition, uses the Streptococcus strain and the delbrucki subsp cream strain. Bulgarian image1. This report deals with Streptococcus thermophilus and lackbacillus delbruecki subsp strains. During fermentation, glucose was isolated to bulgaricus at the bottom of milk, as well as mixed crops, including Streptococcus thermophilus and delbrucki subsp. Bulgarianto starter cultures comprising the strains and to dairy products made with the crops. The present method also refers to the use of the strains to decrease the lactose content of a fermented food product and to reinforce the growth of probiotic BB-12®. Claim 1: A strain of Streptococcus thermophilus that ferments galactose, wherein the strain carries a mutation in the DNA sequence of the glcK gene encoding a glucokinase protein, wherein the mutation inactivates the glucokinase protein or has a negative effect on the expression of the gen.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 thermophilus y las cepas mutantes de Lactob
