ABSTRACT: The growth rate of two probiotic strains with documented health effects was studied in ultra-high temperature treated milk separately and beside each other. The probiotic strains were Lactobacillus acidophilus (La-5) and Bifidobacterium lactis (Bb-12). Fermentation was followed for 12 h at 37 ˚C and the samples were analyzed for pH, titratable acidity and viable counts of probiotic ba...

background and objectives: importance of development of novel probiotic fermented milk and challenge made for its acceptability is well known. in this research, the impact of different inoculation sizes of yogurt and dl-type starter culture (mesophilic and thermophilic lab) on titratable acidity, viscosity, sensorial and microbial properties of fermented milk was investigated; and finally, prob...

The taxonomic standing of Bifidobacterium lactis and Bifidobacterium animalis was investigated using a polyphasic approach. Sixteen representatives of both taxa were found to be phenotypically similar and shared more than 70% DNA-DNA relatedness (76-100%), which reinforces the conclusions of previous studies in which B. lactis and B. animalis were considered to be one single species. However, t...

background and objectives: dental caries, caused by oral microbial flora, is considered as one of the most common infectious diseases in human. the aim of this study was to determine the effect of short-term consumption of probiotic yogurt containing bifidobacterium lactis on salivary streptococcus mutans and lactobacilli in students with initial stages of dental caries. materials and methods: ...

Objectives. The aim of the study is to compare the clinical effectiveness of the probiotics-Saccharomyces boulardii and Bifidobacterium lactis-in children who had been diagnosed with rotavirus gastroenteritis. Materials and methods. Seventy five patients aged between 5 months-5 years diagnosed as rotavirus gastroenteritis were included in the study. The patients diagnosed as rotavirus gastroent...

CONTEXT Constipation is a very common symptom in the general population. One way of non-pharmacological treatment of constipation is through the addition of probiotics to food. OBJECTIVES The aim of this study was to evaluate de effect of the consumption of a fresh cheese, enriched with Bifidobacterium lactis Bi-07 on the symptoms of constipated women. METHODS A randomized controlled trial,...

Two commercially available Bifidobacterium spp. (Bifidobacterium infantis and Bifidobacterium lactis) were compared for their capacities to protect immunodeficient bg/bg-nu/nuand bg/bg-nu/+mice from orogastric and lethal candidiasis. Both Bifidobacterium spp. prolonged the survival of Candida albicans-colonized adult and neonatal bg/bg-nu/numice. The bifidobacteria affected the production of an...

The proteolytic system of Bifidobacterium animalis subsp. lactis was analyzed, and an intracellular endopeptidase (PepO) was identified and characterized. This work reports the first complete cloning, purification, and characterization of a proteolytic enzyme in Bifidobacterium spp. Aminopeptidase activities (general aminopeptidases, proline iminopeptidase, X-prolyl dipeptidylaminopeptidase) fo...

Probiotics are bacteria that are commercially available as dietary supplements. One of the important properties of probiotics is their ability to survive in the intestine. Recent evidence has identified kynurenic acid (KYNA) as a bactericidal constituent of intestinal fluid. These data led us to study the influence of KYNA on the viability of selected probiotics. We found that KYNA supported th...
