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, ...

The developing intestinal microbiota of breast-fed infants is considered to play an important role in the priming of the infants' mucosal and systemic immunity. Generally, Bifidobacterium and Lactobacillus predominate the microbiota of breast-fed infants. In intervention trials it has been shown that lactobacilli can exert beneficial effects on, for example, diarrhea and atopy. However, the Lac...

INTRODUCTION Many reports in literature have underlined particular features of Lactobacillus paracasei subsp paracasei F19, however a critical review of main clinical outcomes has not been performed so far. OBJECTIVES This review summarizes the most relevant reports, in terms of clinical benefits, of Lactobacillus paracasei subsp paracasei F19 administration reviewing it’s historical backgrou...

Background and Objective: The aim of this study was to compare the cytotoxic effects of local probiotic bacteria, including Lactobacillus paracasei, Lactobacillus brevis, while isolated from “Tarkhine” food and the induction of apoptosis in the HT–29 human colon adenocarcinoma cell line and normal fibroblasts. Methods: HT–29 and L–929 cell lines were trea...

One hundred eighty four strains belonging to the species Lactobacillus casei, L. paracasei and L. rhamnosus were screened for their ability to grow under aerobic conditions, in media containing heme and menaquinone and/or compounds generating reactive oxygen species (ROS), in order to identify respiratory and oxygen-tolerant phenotypes. Most strains were able to cope with aerobic conditions and...

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 Allergies are becoming a serious health burden in developed countries. Increasing numbers of clinical trials and animal experiments show that probiotics are new promising tools in allergy prophylaxis. In the present work we compared anti-allergic properties of the recently described probiotic mixture of Lactobacillus casei LOCK0900, L. casei LOCK0908 and L. paracasei LOCK0919 and L. ...

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...

We investigated the effects of the predominant lactic acid bacteria (LAB) on the fermentation characteristics and aerobic stability of total mixed ration (TMR) silage containing soybean curd residue (SC-TMR silage). The SC-TMR materials were ensiled in laboratory silos for 14 or 56 days. LAB predominant in SC-TMR silage were identified (Exp. 1). Lactobacillus fermentum (L. fermentum) and Strept...

Lactic acid bacteria, act as probiotics, isolated from goat milk has various medicinal properties. The studies have found out that the LAB of goat milk plays an important role in prevention of colon and colorectal cancer. It has been observed that along with biologically active peptides, bacterial species of LAB like L. plantarum and L. paracasei has inhibited the proliferation of HeLa cell lin...
