Aminopeptidase activities of Propionibacterium freudenreichii dairy isolates
This study was undertaken to achieve more information on the aminopeptidase activities expressed in Propionibacterium freudenreichii strains naturally occurring in milk and dairy products. Fifty four strains belonging to both subspecies freudenreichii and shermanii were analyzed for activity towards different amino acyl β-naphthylamide (βNA) derivatives. The ability to efficiently hydrolyze ami...
متن کاملOccurrence of Propionibacterium freudenreichii bacteriophages in swiss cheese.
We isolated bacteriophages active against Propionibacterium freudenreichii from 16 of 32 swiss cheese samples. Bacteriophage concentrations ranged from 14 to 7 x 10(5) PFU/g, depending on the sample and the sensitive strain used for detection. Only a few strains, 8 of the 44 strains of P. freudenreichii in our collection, were sensitive. We observed that multiplication of bacteriophages occurre...
متن کاملEmmental Cheese Environment Enhances Propionibacterium freudenreichii Stress Tolerance
Dairy propionibacteria are actinomycetales found in various fermented food products. The main species, Propionibacterium freudenreichii, is generally recognized as safe and used both as probiotic and as cheese starter. Its probiotic efficacy tightly depends on its tolerance towards digestive stresses, which can be largely modulated by the ingested delivery vehicle. Indeed, tolerance of this bac...
متن کاملIn vitro Assessment of Some Probiotic Properties of Lactobacillus fermentum Isolated from Pickled Garlic
Background: Dominant Lactic Acid Bacteria (LAB) originally isolated from traditional non-dairy fermented foods, may harbor unique characteristics such as probiotic properties. In this research, probiotic potential of dominant LAB isolated from pickled garlic was studied. Methods: After isolation of dominant LAB from pickled garlic produced with apple cider vinegar, the isolate was identified...
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 ...
