Surface proteins of Propionibacterium freudenreichii are involved in its anti-inflammatory properties.
UNLABELLED Propionibacterium freudenreichii is a beneficial bacterium used in the food industry as a vitamin producer, as a bio-preservative, as a cheese ripening starter and as a probiotic. It is known to adhere to intestinal epithelial cells and mucus and to modulate important functions of the gut mucosa, including cell proliferation and immune response. Adhesion of probiotics and cross-talk ...
متن کاملIdentification of proteins involved in the anti-inflammatory properties of Propionibacterium freudenreichii by means of a multi-strain study
Propionibacterium freudenreichii, a dairy starter, can reach a population of almost 109 propionibacteria per gram in Swiss-type cheese at the time of consumption. Also consumed as a probiotic, it displays strain-dependent anti-inflammatory properties mediated by surface proteins that induce IL-10 in leukocytes. We selected 23 strains with varied anti-inflammatory potentials in order to identify...
متن کاملPropionibacterium freudenreichii Surface Protein SlpB Is Involved in Adhesion to Intestinal HT-29 Cells
Propionibacterium freudenreichii is a beneficial bacterium traditionally used as a cheese ripening starter and more recently for its probiotic abilities based on the release of beneficial metabolites. In addition to these metabolites (short-chain fatty acids, vitamins, and bifidogenic factor), P. freudenreichii revealed an immunomodulatory effect confirmed in vivo by the ability to protect mice...
متن کاملLipase and Esterase Activities of Propionibacterium freudenreichii subsp. freudenreichii.
The lipase and esterase activities of eight strains of dairy Propionibacterium freudenreichii subsp. freudenreichii were studied. A lipase activity was detected on whole cells and in the culture supernatant. The highest activity was expressed at 45 degrees C and pH 6.8. An esterase activity was also detected in the culture medium. The electrophoresis of the intracellular fractions of the cells ...
متن کاملData from an integrative approach decipher the surface proteome of Propionibacterium freudenreichii
The surface proteins of the probiotic Propionibacterium freudenreichii were inventoried by an integrative approach that combines in silico protein localization prediction, surface protein extraction, shaving and fluorescent CyDye labeling. Proteins that were extracted and/or shaved and/or labeled were identified by nano-LC-MS/MS following trypsinolysis. This method's combination allowed to conf...
