What are the interactions of lactic acid bacteria and Propionibacteria?
IMPORTANCE Interactions of lactic acid bacteria (LAB) are often studied in association with yeasts or propionibacteria in various fermented food products, and the mechanisms underlying their interactions are being quite well characterized. Concerning interactions between LAB, they have mainly been investigated to test antagonistic interactions.
What are thermophilic lactic acid bacteria?
The thermophilic lactic acid bacteria are best known for their role in yoghurt-type products and as ripening agents in Swiss-type and Italian cheeses. There are now several studies, which show the broad spectrum of strains used for the manufacture of a great variety of products and which point to an interesting pool of potentially useful starters.
Does Propionibacterium freudenreichii cause apoptosis?
We have previously shown that consumption of Propionibacterium freudenreichiiby humans increased the amount of this probiotics in feces but also increased the total short chain fatty acids to a concentration of 50 mM [48]. These propionibacterial metabolites produced in vivo in the gut [22, 49, 50] accordingly trigger apoptosis [3]
Is lacticin 3147 a pore-forming bacteriocin?
The results suggest that lacticin 3147 is a pore-forming bacteriocin which acts on a broad range of gram-positive bacteria, including Listeria monocytogenes, and Bacillus subtilis.
