“…According to that, different food matrices have been used as probiotic isolation source. In particular, foods containing probiotic bacteria are strongly linked to fermented dairy products, such as cheese, which is considered both a source and a good carrier of probiotics [21,22]. Cheese is characterized by optimal pH values (ranging from 4.8 to 5.6), good buffering capacity, and high fat content, which protects probiotics during the passage through the gastrointestinal tract (GIT) [23].…”

Piacentinu Ennese PDO Cheese as Reservoir of Promising Probiotic Bacteria

et al. 2019

Piacentinu Ennese is a protected designation of origin (PDO) cheese produced in the surrounding area of Enna (Sicily, Italy), using raw ewe’s milk without the addition of any starter cultures. In the present study, the Lactobacillus population of Piacentinu Ennese PDO cheese was in vitro screened in order to select promising probiotic strains to be further used in humans. One hundred and sixty-nine lactic acid bacteria (LAB) were isolated from 90 days ripened cheeses and identified by Rep-PCR genomic fingerprinting, using the (GTG)5-primer, and by MALDI-TOF MS. One hundred and thirteen (113) isolates belonging to QPS-list species were characterized for both safety and functional properties. All tested isolates were considered safe because none showed either gelatinase, DNase, mucinase, or hemolytic activity. Tolerance to lysozyme, bile salts, and acidic conditions, along with ability to survive under simulated gastrointestinal digestion, were observed. In addition, based on antimicrobial activity against pathogens, cell surface characteristics, Caco-2 adhesion abilities, and anti-inflammatory potential, it was possible to confirm the strain-dependent functional aptitude, suggesting that Piacentinu Ennese PDO cheese may be considered a precious source of probiotic candidates.
