Responses of Staphylococcus aureus exposed to HCl and organic acid stress.

Project description:Staphylococcus aureus is an important food poisoning bacterium. In food preservation, acidification is a well-known method. Permeant weak organic acids, like lactic and acetic acids, are known to be more effective against bacteria than inorganic strong acids (e.g., HCl). Growth experiments and metabolic and transcriptional analyses were used to determine the responses of a food pathogenic S. aureus strain exposed to lactic acid, acetic acid, and HCl at pH 4.5. Lactic and acetic acid stress induced a slower transcriptional response and large variations in growth patterns compared with the responses induced by HCl. In cultures acidified with lactic acid, the pH of the medium gradually increased to 7.5 during growth, while no such increase was observed for bacteria exposed to acetic acid or HCl. Staphylococcus aureus increased the pH in the medium mainly through accumulation of ammonium and the removal of acid groups, resulting in increased production of diacetyl (2,3-butanedione) and pyrazines. The results showed flexible and versatile responses of S. aureus to different types of acid stress. As measured by growth inhibition, permeant organic acid stress introduced severe stress compared with the stress caused by HCl. Cells exposed to lactic acid showed specific mechanisms of action in addition to sharing many of the mechanisms induced by HCl stress. Data is also available from http://bugs.sgul.ac.uk/E-BUGS-87

Food-associated Lactiplantibacillus plantarum C9O4 reverts inflammation and apoptosis in intestinal epithelial cells: a proteomic insight

Project description:Nowadays, Western diets and lifestyle lead to an increasing occurrence of chronic gut inflammation, that represents an emerging health concern with still a lack of successful therapies. Fermented foods, and their associated Lactic Acid Bacteria, have recently regained popularity for their probiotic potential including the maintenance of gut homeostasis by modulating the immune and inflammatory response. Our study aims to investigate the cross-talk between the food-borne strain Lactiplantibacillus plantarum C9O4 and intestinal epithelial cells in an in vitro inflammation model. Cytokines profile shows the ability of C9O4 to significantly reduce levels of IL-2, IL-5, IL-6, and IFN-γ. Proteomic functional analysis reveals an active host-microbe interaction that highlights an immunoregulatory role of C9O4, able to revert both the detrimental effects of IFN-γ through the JAK/STAT pathway and the apoptosis process in inflamed cells. These results suggest a promising therapeutic role of fermented food-associated microbes for the management of gastrointestinal inflammatory diseases.

Differences between static supernatant-, static biofilm- and flow biofilm-cells of two Lactiplantibacillus plantarum strains.

Project description:This study was conducted to analyze phenotypic and proteomic differences of two Lactiplantibacillus plantarum strains (WCFS1, model strain from human saliva, and CIP104448, stool isolate) when a biofilm was produced under static conditions (well researched), or with the addition of flow (novel).

Proteomic profiling of extracellular vesicles of the Lactiplantibacillus plantarum strains

Project description:The study was conducted on a model of Lactiplantibacillus plantarum, one of the most studied species widely used in the food industry as a probiotic microorganism and/or microbial starter culture. As a result of step-by-step selection from the L. plantarum 8p-a3 strain isolated from the «Lactobacterin» probiotic, the L. plantarum 8p-a3-Clr-Amx strain was obtained, showing increased resistance, compared with the parent strain, to amoxicillin-clavulanic acid (MIC 20 mcg/ml) and clarithromycin (MIC 10 mcg/ml). The L. plantarum strain DMC-S1 was isolated from the intestine of Drosophila melanogaster Canton-S line. Extracellular vesicles of this bacterium can play a significant role in the drug-resistance development and host-microbe interactions.

LACTIPLANTIBACILLUS PLANTARUM STRENGTHENS THE INTESTINAL BARRIER: INVOLVEMENT OF THE ENDOCANNABINOIDOME

Project description:Probiotics have been suggested to ameliorate the function of the intestinal epithelial barrier and so have several mediators and receptors of the expanded endocannabinoid system, the endocannabinoidome (eCBome). Here we cocultured three live strains of Lactiplantibacillus plantarum with intestinal epithelial organoids to study their effects on the gut barrier function and the possible involvement of the eCBome in this effect. All three L.plantarum strains variously reduced the trans-epithelial permeability of intestinal organoids and promoted increased mRNA expression of several tight junction proteins and intestinal barrier proteins. Concomitantly, the three strains upregulated the expression of genes encoding biosynthetic enzymes (i.e., NapePLD, Abdh4, Gde1, Daglb) and receptors (i.e., Cnr1, Cnr2, Gpr55, and Ppara), while concurrently downregulating the expression of two essential catabolic enzymes (i.e. Faah and Naaa), involved in the signaling of several eCBome mediators known for their role in regulating the intestinal epithelial barrier. Selective inhibitors of eCBome mediator degrading enzymes FAAH and MAGL, i.e., URB597 and JZL184, increased N-acyl-ethanolamine (NAE) and 2-monoacylglycerol (2-MAG) levels, respectively, enhanced the expression of intestinal epithelial barrier genes and reduced the trans-epithelial permeability of organoids, as for L. plantarum strains. Interestingly, inflammation-induced trans-epithelial permeability in organoids was also reversed by both FAAH and MAGL inhibitors. We surmise that elevated endogenous levels of either NAEs or 2-MAGs promote improvement in small intestine trans-epithelial permeability and that L. plantarum strains may exploit this mechanism to promote these beneficial effects.
