    Abstract: A Bacillus strain characterized by (i): sensitivity for ampicillin, vancomycin, gentamicin, kanamycin, streptomycin, erythromycin, clindamycin, tetracycline and chloramphenicol; (ii) antimicrobial activity against E. coli and Clostridium perfringens; and (iii) a sporulation percentage of at least 80 when measured after 2 days of incubation. The invention further relates to a method for selecting such strains. Many of the identified strains according to the invention are of the species Bacillus amyloliquefaciens. Some of the Bacillus amyloliquefaciens were further identified as Bacillus amyloliquefaciens subsp. amyloliquefaciens whereas others were identified as amyloliquefaciens subsp. plantarum. A Bacillus strain of the invention may be used as a feed additive to animal feed where it has a probiotic effect.

    Abstract: Described are mutant Streptococcus thermophilus strains and mutant Lactobacillus delbrueckii subsp. bulgaricus strains that excrete glucose into milk when the milk is inoculated and fermented with such strains. Methods for obtaining such strains without genetic modification are described, including methods for obtaining such Streptococcus thermophilus strains by selecting and isolating from a pool of Streptococcus thermophilus strains derived from a galactose-fermenting Streptococcus thermophilus mother strain a pool of Streptococcus thermophilus strains which are resistant to 2-deoxyglucose, and selecting and isolating from the pool of Streptococcus thermophilus strains which are resistant to 2-deoxyglucose a Streptococcus thermophilus strain which exhibits a growth rate in M17 medium+2% galactose higher than its growth rate in M17 medium+2% glucose. The strains are useful for decreasing the lactose content of a fermented food product and for boosting growth of the probiotic BB-12®.

    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 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.
