The nature of some growth stimulatory substances for Lactobacillus delbrueckii.
In addition to the usual amino acids and vitamins, Lactobacilus delbrekii strain 730 (ATCC 9649) has been shown to require pyridoxamine phosphate (McNutt and Snell, 1950), thymidine (Kitay, et al., 1950), and an unsaturated fatty acid (e. g., oleic acid) (Kitay and Snell, 1950) for growth. In addition to these absolute requirements for growth, partial acid hydrolyzates of casein further stimula...
متن کاملDNA Probe for Lactobacillus delbrueckii.
From a genomic DNA library of Lactobacillus delbrueckii subsp. bulgaricus, a clone was isolated which complements a leucine auxotrophy of an Escherichia coli strain (GE891). Subsequent analysis of the clone indicated that it could serve as a specific DNA probe. Dot-blot hybridizations with over 40 different Lactobacillus strains showed that this clone specifically recognizes L. delbrueckii subs...

متن کاملExopolysaccharides Produced from Lactobacillus delbrueckii subsp. bulgaricus
Lactobacillus delbrueckii subsp. bulgaricus, which has been widely used as a fermented milk starter, is a type of probiotic, and certain strains are able to produce exopolysaccharide (EPS). EPS produced from L. bulgaricus contributes to the physical and biological function of dairy products by regulating immune response, and this tendency seems to place EPS with acidic groups. To date, six type...
متن کاملPyelonephritis and Bacteremia from Lactobacillus delbrueckii
Lactobacilli are normal colonizers of the oropharynx, gastrointestinal tract, and vagina. Infection is rare, but has been reported in individuals with predisposing conditions. Here we describe the case of a woman with pyelonephritis and bacteremia in which Lactobacillus delbrueckii was determined to be the causative agent.
