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 ...

the objectives of this paper were production of probiotic yoghurt using l. paracasei ssp. tolerans, and evaluation of ph changes, viable counts, and organoleptic properties of the produced yoghurt. it was observed that the ph decrease during the fermentation period was faster in the milk inoculated with l. paracasei ssp. tolerans plus starter culture. there was a gradual decrease in ph in both ...

Lactic acid bacteria are probiotics widely used in functional food products, with a variety of beneficial effects reported. Recently, intense research has been carried out to provide insight into the mechanism of the action of probiotic bacteria. We have used gene array technology to map the pattern of changes in the global gene expression profile of the host caused by Lactobacillus administrat...

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...

A personalized probiotic microfluidic chip system has been established and used to screen the probiotics which had the highest value of IFN-γ/IL-10 or IL-10/IFN-γ among six probiotics, including L. paracasei BRAP01, L. acidophilus AD300, B. longum BA100, E. faecium BR0085, L. rhamnosus AD500, and L. reuteri BR101. One hundred volunteers were included and their PBMCs were collected and stimulate...

The aim of this study was to evaluate the phenotypic and genetic heterogeneity of lactic acid bacteria (LAB) isolated from "Alheira", a fermented sausage produced in Portugal. LAB were identified to genus and species level by phenotypic characteristics, using genus or species-specific primers and sequencing of the gene encoding 16S rRNA. Two-hundred and eighty-three isolates were grouped into 1...

Studies showed that specific probiotics might provide therapeutic benefits in inflammatory bowel disease. However, a rigorous screening of new probiotics is needed to study possible adverse interactions with the host, particularly when intended for administration to individuals with certain health risks. In this context, the objective of this study was to investigate the role of three lactobaci...
