    Abstract: The present invention relates to mutants of lactic acid bacteria which are resistant towards the antibiotic D-cycloserine and/or functionally equivalent antibiotics and which were found to give an increased texture when grown in milk while maintaining the other growth properties of the parent strain. The present invention, furthermore, relates to compositions comprising such mutants, and to dairy products fermented with the lactic acid bacteria resistant towards D-cycloserine and/or functionally equivalent antibiotics.

    Abstract: 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®.

    Abstract: The Lactobacillus curvatus strain deposited as DSM18775 is used as a biopreservative culture in a wide range of meat products due to its production of bacteriocin. The present invention relates to Lactobacillus curvatus strains having an extended lag phase of at least 24 hours at 30° C. relative to DSM18775. In a presently preferred embodiment, the strains are mutants of DSM18775, such as the Lactobacillus curvatus strain deposited as DSM32590 and the Lactobacillus curvatus strain deposited as DSM 32591. Further, the invention relates to a method for inhibiting Listeria in a food product comprising adding bacteria of a Lactobacillus curvatus strain according to the invention to a food product in a concentration of at least 105 CFU/g.
