Nitrites commonly found in food, especially in fermented vegetables, are potential carcinogens. Therefore, limiting nitrites in food is critically important for food safety. A Lactobacillus strain (Lactobacillus sp. DMDL 9010) was previously isolated from fermented vegetables by our group, and is not yet fully characterized. A number of phenotypical and genotypical approaches were employed to c...

At the 1920 meeting of the Society of American Bacteriologists a paper, published only in abstract form (Sherman, 1921), presented some characteristics of Lactobacillus bulgaricus, differentiating this organism from certain other lactobacilli. Eighteen cultures of Lactobacillus bulgaricus were then studied; a number of Lactobacillus casei; a few cultures from feces, assumed to belong to the Lac...

We previously discovered a symbiotic lactic acid bacterial (LAB) microbiota in the honey stomach of the honeybee Apis mellifera. The microbiota was composed of several phylotypes of Bifidobacterium and Lactobacillus. 16S rRNA gene sequence analyses and phenotypic and genetic characteristics revealed that the phylotypes isolated represent seven novel species. One grouped with Lactobacillus kunke...

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...

Early feeding (started during gut metamorphosis and establishment of the hypothalamic-pituitary-interrenal axis) with probiotic-supplemented diets, besides modifying the intestinal microflora, evoked profound effects on the physiology of fish larvae. Using rotifers and Artemia as living vectors, the autochthonous bacterium Lactobacillus delbrueckii delbrueckii or a multispecies probiotic formul...

During the past few years several investigators have reported the isolation of lactobacilli or lactobacilli-like organisms from the rumen liquor of cattle and sheep. Gall and Huhtanen (1951) isolated several gram positive, nonsporeforming rods from rumen fluid which produced lactic acid from glucose, but they were not further identified. Some lactobacilli found by Rodwell (1953) in a sheep's ru...

background probiotics have been used for dairy products such as yogurt and yogurt drinks, however cholesterol content and lactose intolerance are important drawbacks. recently, consumption of non-dairy probiotic food especially for probiotic drink products has been intensified. objectives this research was conducted to determine the suitability of peach as a raw material for producing probiotic...

We identified the proteins synthesized by Lactobacillus delbrueckii subsp. bulgaricus strain LBB.B5 in laboratory culture medium (MRS) at 37°C and milk at 37 and 4°C. Cell-associated proteins were measured by gel-free, shotgun proteomics using high-performance liquid chromatography coupled with tandem mass spectrophotometry. A total of 635 proteins were recovered from all cultures, among which ...
