Development of a symbiotic cottage cheese added with Lactobacillus delbrueckii UFV H2b20 and inulin
نویسندگان
چکیده
The aim of the study was to develop a symbiotic cottage cheese containing Lactobacillus delbrueckii UFV H2b20 and inulin, and to evaluate the survival of this bacterium when the cheese was exposed to conditions simulating those found in the gastro-intestinal tract. Throughout the entire whole shelf-life period of the cheese, the probiotic cell counts were higher than those recommended for probiotic products containing 5% of inulin. The probiotic bacterium exhibited satisfactory resistance to low pH values and to high concentrations of bile salts. The addition of probiotic cells and inulin generated no alterations in the physicochemical characteristics of cheese. 2009 Elsevier Ltd. All rights reserved.

Identification of Lactobacillus UFV H2B20 (probiotic strain) using DNA-DNA hybridization
Sequence analyses of the 16S rDNA gene and DNA-DNA hybridization tests were performed for identification of the species of the probiotic Lactobacillus UFV H2b20 strain. Using these two tests, we concluded that this strain, originally considered Lact. acidophilus, should be classified as Lact. delbrueckii.
متن کاملEffect of probiotics on the development of dimethylhydrazine-induced preneoplastic lesions in the mice colon.
PURPOSE To determine the effect of probiotics on the development of chemically induced (1, 2-dimethylhydrazine) colonic preneoplastic lesions, in mice. METHODS The animals were divided into five groups. The control group was injected with carcinogen alone and the other groups also received probiotics (1- Lactobacillus delbrueckii UFV-H2b20; 2- Bifidobacterium animalis var. lactis Bb12; 3- L. ...

Lactobacillus delbrueckii UFV-H2b20 has been shown to increase clearance of bacteria injected into the blood of germ-free mice. Moreover, it induces the production of type 1 cytokines by human peripheral mononuclear cells. The objective of the present study was to investigate the production of inflammatory cytokines [interleukin-12 (IL-12 p40), tumor necrosis factor-alpha (TNF-alpha), and inter...

We evaluated the ability of Lactobacillus delbrueckii UFV H2b20, a probiotic candidate, to stimulate the production of inflammatory cytokines and to induce macrophage activation and Th1 differentiation in peripheral blood mononuclear cells (PBMC) from healthy volunteers. Our results show that PBMC stimulated with heat-killed Lact. delbrueckii produced elevated levels of IL-12, IFN-gamma and TNF...

The ability of Lactobacillus acidophilus UFV-H2B20 to antagonize Salmonella enterica subsp. enterica ser. Typhimurium and to reduce the pathological consequences for the host was determining using conventional and gnotobiotic animals. Conventional NIH mice received daily by gavage a 0.1 ml suspension containing about 10 cfu L. acidophilus UFVH2B20 and germfree animals received a single 0.1 ml d...
