The fosABCDXE operon encodes components of a putative fructose/mannose phosphoenolpyruvate-dependent phosphotransferase system and a beta-fructosidase precursor (FosE) that are involved in the fructooligosaccharide (FOS) utilization pathway of Lactobacillus paracasei 1195. The presence of an N-terminal signal peptide sequence and an LPQAG cell wall anchor motif in the C-terminal region of the d...

INTRODUCTION Intestinal lactobacilli have been successfully used as probiotics to treat gastrointestinal disorders, but only limited data are available for the probiotic properties of oral lactobacilli to combat oral diseases. We aimed to characterize oral lactobacilli for their potential probiotic properties according to the international guidelines for the evaluation of probiotics, and to sel...

We aimed at evaluating the association between intestinal Lactobacillus sp. composition and their metabolic activity with the host metabolism in adult and elderly individuals. Faecal and plasma metabolites were measured and correlated to the Lactobacillus species distribution in healthy Estonian cohorts of adult (n = 16; < 48 y) and elderly (n = 33; > 65 y). Total cholesterol, LDL, C-reactive p...

Lactic acid fermentation is a natural method of antimicrobial food protection. Antagonistic activity of Lactobacillus sp. bacteria, taking part in this process, is directed mainly against the same or other microorganisms. In this work we determine the impact of the presence of xylitol and galactosyl-xylitol on the antagonistic activity of 60 Lactobacillus sp. strains against indicator molds (Al...

In the present study, polyphasic analysis [cultivation, combined with the fingerprinting of individual isolates, and denaturing gradient gel electrophoresis (DGGE)] was applied to study whether similar features concerning the diversity and temporal stability of selected bacterial groups could be detected intra-individually in two different niches - the oral cavity and the colon - from ten adult...

Bile salt hydrolases (BSH) results in microbes releasing enzymes conferring physiological functions for both the producing organisms and host subsequently lower serum cholesterol. In recent years, these attributes have generated interest towards screening of lactic acid bacteria (LAB) functional food production. this present study, lactobacilli (n=34) (13 L. casei, 6 paracasei, 11 brevis, 3 pen...

Objective: The aim of the present study was to assess the antithrombotic properties of different strains of orally available antithrombotic lactic acid bacteria (LAB). Research Methods & Procedures: Antithrombotic activity, antiplatelet reactivity and/or thrombolytic activity, were measured in seven strains of LAB and LAB cell-free-extracts (LAB filtrates) using the shear-induced platelet react...
