Emerging Nonthermal Technologies for the Production of Postbiotics

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 6, November 2025.
ABSTRACT Postbiotics, defined as nonliving microbial cells and their components that confer health benefits to the host, represent a significant advancement in functional foods and dietary supplements. Compared to probiotics and prebiotics, postbiotics offer advantages in product stability, safety, and formulation flexibility. In general practice, heat

Rēwena sourdough fermentation with Propionibacterium freudenreichii: Impacts on structure and texture [PDF]

Rēwena sourdough is a unique form of bread that has cultural significance in Māori cuisine. It is unique due to its use of mashed potatoes as a carbohydrate source in its starter culture (Sun et al. 2022).

Genomic diversity of 24 Propionibacterium freudenreichii 1 strains

, 2011
High-throughput sequencing technologies have the potential to decipher genomic diversity at a moderate cost. Propionibacterium freudenreichii is an Actinobacterium used in cheese technology (responsible for aroma and holes in Swiss cheese) and that has

Genome-scale model guided design of Propionibacterium for enhanced propionic acid production

Metabolic Engineering Communications, 2018
Production of propionic acid by fermentation of propionibacteria has gained increasing attention in the past few years. However, biomanufacturing of propionic acid cannot compete with the current oxo-petrochemical synthesis process due to its well ...

Freezing of Vaginal Swabs Prior to DNA Purification Does Not Statistically Significantly Affect Microbiome Composition

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
The vaginal microbiome is vital to women's health. We assessed the effects of short‐term storage and human DNA depletion on microbial profiles. While overall composition remained stable, trends in beta diversity and internal controls suggest subtle effects on low‐abundance species, highlighting the need for robust analytical design.

Detection of aminotransferase activity of Propionibacterium freudenreichii after SDS-PAGE

, 2002
Aminotransferases (ATs) had previously been detected after native electrophoresis. We show now that aminotransferase(s) of Propionibacterium freudenreichii can be detected after sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE ...

Isolation, Characterisation and Vitamin B12 Production Optimization of P. freudenreichii from Turkish Traditional Kars Gravyer

Fermentation
In this study, nine different Propionibacterium freudenreichii strains were isolated from Kars Gravyer produced by traditional methods in Turkey and identified by sequencing the 16S–23S intergenic region using species-specific primers.
