The influence of lactic acid bacteria (LAB) on CD4(+)Foxp3(+) cells has not been investigated, although it has been reported that CD4(+)Foxp3(+) cells might be involved in the inhibition of allergic symptoms. Hence we examined the effect of orally administered LAB on CD4(+)Foxp3(+) generation. Oral administration of Lactobacillus plantarum NRIC0380 significantly inhibited antigen-specific IgE p...

Lactic acid bacteria (LAB) are essential for the manufacture of fermented dairy products. Studies on the physiology, biochemistry and genetics of these microorganisms over the last century have contributed considerably to the improvement of fermentation processes and have resulted in better and safer products. Nevertheless, the potential of LAB is far from being maximized. The sophistication of...

Most data dealing with the biopreservative activity of lactic acid bacteria (LAB) are focused on their antibacterial effects. Food spoilage by mould and the occurrence of their mycotoxins constitute a potential health hazard. Development of biological control should help improve the safety of products by controlling mycotoxin contamination. Data have actually shown that many LAB can inhibit mou...

Some lactic acid bacteria (LAB) secrete a polysaccharide polymer. This extracellular polysaccharide, or "exopolysaccharide" (EPS), is economically important because it can impart functional effects to foods and confer beneficial health effects. LAB have a "Generally Recognized As Safe" (GRAS) classification and are likely candidates for the production of functional EPSs. Current challenges are ...

The effect of Monascus purpureus extract (MPE) on probiotic lactic acid bacteria (LAB) was investigated to ascertain its application in fermented foods. Viable count of LAB was not affected after 24 hours of incubation in Man Rogosa Sharpe (MRS) broth containing MPE. The agar well-diffusion assay did not show any inhibition zone. The biotransformation of isoflavone glycosides by LAB in culture ...

Lactic acid bacteria (LAB) were isolated from ovine milk and cheeses manufactured in the South Region of Brazil. Among 112 bacterial isolates investigated, 59 were chosen through a screening for LAB. Among these 59 strains of LAB, 21% showed antimicrobial, proteolytic and lipolytic activities. Based on this screening, Lactobacillus plantarum LCN 17 and Lactobacillus rhamnosus LCN 43 were select...

Lactic acid bacteria (LAB) are popularly used as probiotics, and some strains of LAB have anti-allergic functions in vivo. Although in vitro studies show that LAB modulate the T helper type (Th) 1/Th2 balance and inhibit IgE secretion by inducing IL-12, it is not known how LAB regulates allergies in vivo. In this study, we evaluated in vivo IL-12 production after oral administration of Lactobac...

Lactic acid bacteria (LAB) are receiving increased attention for use as cell factories for the production of metabolites with wide use by the food and pharmaceutical industries. The availability of efficient tools for genetic modification of LAB during the past decade permitted the application of metabolic engineering strategies at the levels of both the primary and the more complex secondary m...

Exopolysaccharides as well as other bioactive substances of Lactic acid bacteria (LAB) attracted much attention due to its specific structure and functions, e.g. tolerance to gastrointestinal (GI) stress, adhesion on the intestinal mucosa, inhibition against pathogens, and modulation of immune system. In this mini-review, we have summarized the recent progress of exopolysaccharides of Lactobaci...
