Acetate stimulation of Lactobacillus delbrueckii and its replacement of nucleosides.
Studies of the acetate stimulation of lactobacilli have led to the discovery of two acetatereplacing factors now known as lipoic and mevalonic acids (Guirard et al., 1946; Skeggs et al., 1956). These two acetate-replacing factors have been shown to be active for many microorganisms. However, there still remain some lactic acid bacteria which require acetate for early growth and for which lipoic...

متن کاملInactivation of Lactobacillus delbrueckii bacteriophages by heat and biocides.
The effect of several biocides and thermal treatments on the viability of four Lactobacillus delbrueckii phages was investigated. Time to achieve 99% inactivation of phages at 63 and 72 degrees C in three suspension media (Tris Magnesium Gelatin (TMG) buffer, Man Rogosa Sharpe (MRS) broth and reconstituted nonfat dry skim milk (RSM)) was calculated. Thermal resistance depended on the phage cons...
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 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.
