Antifungal Properties of Dairy Propionibacteria
Today global agriculture is facing major challenges. The world’s population is growing rapidly and we need to meet the increasing need for food with new strategies, including environmentally sustainable practices. Production must be enhanced with optimised resource utilisation and improved storage and distribution techniques. In addition, consumer demands for a reduction in artificial preservat...
متن کاملDairy Propionibacteria: Versatile Probiotics
Dairy propionibacteria are used as cheese ripening starters, as biopreservative and as beneficial additives, in the food industry. The main species, Propionibacterium freudenreichii, is known as GRAS (Generally Recognized As Safe, USA, FDA). In addition to another dairy species, Propionibacterium acidipropionici, they are included in QPS (Qualified Presumption of Safety) list. Additional to the...
متن کاملPromising immunomodulatory effects of selected strains of dairy propionibacteria as evidenced in vitro and in vivo.
Immunomodulatory properties of 10 dairy propionibacteria, analyzed on human peripheral blood mononuclear cells (PBMCs), revealed a highly strain-dependent induction of anti-inflammatory cytokine interleukin 10 (IL-10). Two selected strains of Propionibacterium freudenreichii showed a protective effect against two models of colitis in mice, suggesting a probiotic potential predicted by immune-ba...
متن کاملGlycerol Enhances the Antifungal Activity of Dairy Propionibacteria
Dairy propionibacteria are widely used in starter cultures for Swiss type cheese. These bacteria can ferment glucose, lactic acid, and glycerol into propionic acid, acetic acid, and carbon dioxide. This research examined the antifungal effect of dairy propionibacteria when glycerol was used as carbon source for bacterial growth. Five type strains of propionibacteria were tested against the yeas...
متن کاملAutolysis in strains of viridans streptococci.
Seven strains of viridans streptococci of the species Streptococcus sanguis, S. mutans and S. mitis were investigated for autolysis. The effect of pH, salt concentration and temperature on the autolytic process was studied in Na2HPO4/NaH2PO4 buffer. Whole cells and walls of all strains autolysed most rapidly at pH values above 7. Autolysis of whole cells of S. sanguis and one strain of S. mitis...
