INTRODUCTION Food supplemented with probiotic bacteria is a rapidly growing sector of the market. The aim of the present study was to evaluate and compare the acid production of selected probiotic strains available in commercial products. METHODS Six Lactobacillus strains (Lactobacillus plantarum 299v and 931; Lactobacillus rhamnosus GG and LB21; Lactobacillus paracasei subsp. paracasei F19, ...

Probiotics could represent an effective alternative to the use of synthetic substances in nutrition and medicine. The data concerning the efficacy of probiotics are often contradictory. This paper focuses on the enhancement of the efficacy of probiotics by their combination with synergistically acting components of natural origin. Maltodextrins can be obtained by enzymatic hydrolysis of starch ...

BACKGROUND The incidence of human Campylobacter jejuni infections is progressively increasing worldwide. Probiotic compounds might open up valuable tools to decrease pathogen burden and subsequent pro-inflammatory immune responses, but in vivo data are scarce. METHODS AND RESULTS Secondary abiotic mice generated by broad-spectrum antibiotic treatment were perorally challenged with the commerc...

Lactic acid fermentation is the simplest and safest way of preserving food and has probably always been used by humans. Species such as Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus paracasei, Lactobacillus acidophilus, and Lactobacillus salivarius are common in the human mucosa, from the mouth to the rectum. In food, L. paracasei and L. rhamnosus are usually associated with d...

BACKGROUND The resistance of Helicobacter pylori to the antibiotic therapy poses the problem to discover new therapeutic approaches. Recently it has been stated that antibacterial, immunomodulatory, and antioxidant properties of lactoferrin are increased when this protein is surface-linked to biomimetic hydroxyapatite nanocrystals. OBJECTIVE Based on these knowledge, the aim of the study was ...

this paper investigates the removal of iron and zinc from aqueous solution with dairy wastewaterin three different biomasses such as lactobacillus delbrueckii ssp bulgaricus (lb-12), streptococcus thermophillus(stm-7) and a combination of both this bacteria culture (yc-380) and the optimization of removal efficiencyusing minitab program. a full 23 factorial design of experiments was applied to ...

Competition of commensal and probiotic bacteria with pathogens for adhesion and colonization is one of the important protective mechanisms of gastrointestinal tract. In this study, we examined the ability of Lactobacillus paracasei to inhibit the adhesion of pathogenic Salmonella enterica to human colon adenocarcinoma Caco-2 cells. Caco-2 cells were grown for 6 or 21 days to obtain nondifferent...
