Dairy propionibacteria as probiotics: recent evidences
World Journal of Microbiology and Biotechnology, 2016Nowdays there is evidence that dairy propionibacteria display probiotic properties, which as yet have been underestimated. The aim of this paper is to review the recent highlights of data representing the probiotic potential of dairy propionibacteria, studied both by general selection criteria (useful for all probiotic potentials), and by more specific

Immunomodulation by propionibacteria
Clinical Immunology Newsletter, 1985The ability of bacteria and bacterial products to modulate the immune response to unrelated antigens is well documented. Propionibacteria are amongst the most potent immunomodulators stimulating cell populations involved in nonspecific resistance. Generally, the activated immune system provides protection from infectious pathogens and malignancies via ...

On the specificity of biotin in the metabolism of propionibacteria
Archives of Biochemistry and Biophysics, 1958Abstract A study of the biotin requirement for succinic acid decarboxylation and glucose fermentation by intact cells of P. pentosaceum has revealed an unsuspected specificity in the action of this vitamin. Thus, whereas biotin and dethiobiotin were found to be mutually replaceable for both glucose fermentation and succinate decarboxylation ...

Incorporation of Propionibacteria in Fermented Milks as a Probiotic
Critical Reviews in Food Science and Nutrition, 2015Propionibacteria are mainly found in dairy products and fermented milks but are found in other foods as well. Dairy propionibacteria have recently shown to exert potential probiotic activities such as production of propionic acid, vitamins, bacteriocins, essential enzymes, and other vital metabolites.

Propionin B, an Antiviral Principle of Propionibacteria
Chemotherapy, 2009A fraction, containing propionins B and C, which was active against Columbia SK virus has now been shown to be active against EMC virus in mice. From this mixture, a chromatographically homogenous substance has been separated. This substance is referred to as propionin B and its amino acid composition is described.

Susceptibility of Cutaneous Propionibacteria to Newer Antibiotics
Chemotherapy, 2009The minimal inhibitory concentrations of 18 newer antibiotics were determined for 33 strains of cutaneous propionibacteria, i.e., P.acnes, P. granulosum and P. avidum. All the strains showed high sensitivity to the penicillin and cephalosporin antibiotics tested. They were mostly resistant to aminoglycosides in therapeutically achievable concentrations,

The unconventional antimicrobial peptides of the classical propionibacteria
Applied Microbiology and Biotechnology, 2010The classical propionibacteria produce genetically unique antimicrobial peptides, whose biological activities are without equivalents, and to which there are no homologous sequences in public databases. In this review, we summarize the genetics, biochemistry, biosynthesis, and biological activities of three extensively studied antimicrobial peptides ...

Genetic Studies in Propionibacteria
1999Owing to the absence of toxicity and valuable biotechnological properties, propionic acid bacteria are widely used in industry (food industry, vitamin B12 production). Genetic approaches may help increase strain productivity, change nutrient requirements, confer phage resistance.
