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 کاملAcetate-replacing Factors for Lactic Acid Bacteria
The stimulatory effect of sodium acetate on growth of lactic acid bacteria was first demonstrated by Snell et al. (1). Guirard et al. (2) investigated the role of acetate in the nutrition of certain lactic acid bacteria and showed that acetate serves a dual purpose in media, (a) that of a buffer and (b) that of a probable precursor of various lipides. It was further demonstrated (3) that some b...
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 کاملLactobacillus delbrueckii as the cause of urinary tract infection.
Lactobacilli are part of the normal bacterial flora of the vagina and are typically considered contaminants when cultured from urine specimens of female patients. Here we describe the case of a female patient with chronic pyuria and urinary tract symptoms in which Lactobacillus delbrueckii was determined to be the causative microorganism.
