Special Issue Information

Dear Colleagues,

This Special Issue, titled “Role of Microorganisms in Functional Dairy Products”, aims to explore the role of microorganisms in enhancing the nutritional, functional, and sensory properties of dairy products, with a focus on the diversity and functionality of probiotic and starter cultures, as well as on emerging microbiome research in the development of novel dairy products. This Special Issue aims to bridge traditional practices and modern molecular approaches and explore the interdisciplinary approaches contributing to the advancement of functional dairy foods.

The role of microorganisms in developing new and improving existing dairy products has long been recognized, but recent advancements in molecular biology, genomics, and bioinformatics have provided new insights into how these microorganisms can enhance the nutritional, functional, and sensory properties of dairy foods. This Special Issue aims to explore the diverse and dynamic role of microorganisms, particularly probiotics and starter cultures, in the development of innovative functional dairy products. We seek to explore and explain the mechanisms through which microorganisms can impact health, improve nutrient bioavailability, and contribute to the sensory properties of dairy products.

This Special Issue will provide a scientific platform for researchers investigating the molecular and functional properties of the microorganisms used in dairy production. It will welcome original research articles, reviews, and short communications focused on the molecular characterization of microbial strains, genomic and metabolomic profiling, the use of bioinformatics tools to understand microbial mechanisms, the role of probiotics in gut health and immune modulation, advancements in fermentation technologies, bioactive compound production, and the regulatory aspects that ensure safety and quality in functional dairy products. Through this Special Issue we aim to provide a deeper understanding of the contribution of microbials to dairy science and advance the development of sustainable, functional dairy products.

We welcome original research articles, reviews, and short communications that provide novel insights into the following topics:

  • The molecular characterization of microbial strains;
  • Genomic and metabolomic profiling;
  • The use of bioinformatics tools to explain the mechanisms underlying the functional properties of microorganisms;
  • The mechanisms of probiotic action, and their impact on gut health, immune modulation, and the bioavailability of nutrients;
  • Innovations in fermentation technologies and the development of dairy products for special dietary needs (lactose-free, enriched with omega-3-fatty acids);
  • Bioactive compound production and the role of microorganisms in producing peptides, exopolysaccharides, and other health-promoting metabolites;
  • The safety and regulatory aspects of functional dairy products, including tools and guidelines for ensuring safety and product quality.

The antimicrobial potential of the strain Lactiplantibacillus plantarum CNPC001 in fermented raw goat milk against contamination indicators (Escherichia coli, Staphylococcus spp., Salmonella spp., as well as yeasts and molds) was assessed. To do this, two distinct treatments were produced in triplicate in raw goat milk, one only with the starter Streptococcus thermophilus QGE (T1) and the other with the starter and Lp. plantarum CNPC001 in co-culture (T2). The main bio-preservative effect of Lp. plantarum CNPC001 in co-culture with S. thermophilus was verified against E. coli and Staphylococcus spp., in which E. coli was completely inhibited at the end of fermentation and Staphylococcus spp. remained below the method threshold (<2.00 log CFU/g) from the 14th day up to the end of storage. For Salmonella spp., a significant difference between the fermented milks was verified at the end of fermentation process, in which the absence of this microorganism was only verified in the T2. No significant differences between the T1 and T2 were verified for yeast and molds. The viability of Lp. plantarum remained above 7 log CFU g−1 for 28 days of storage. Therefore Lp. plantarum CNPC001 in co-culture with S. thermophilus QGE was able to demonstrate a bio-preservative effect in fermented raw goat milk, inhibiting the growth of E. coli, S. aureus, and Salmonella spp. Full article

This study explored the development of a novel whey-based fermented beverage enriched with juice concentrates and health-promoting ingredients, emphasizing its bioactive properties. The formulation included whey protein isolate (5%), juice concentrates (10% apple, raspberry, and cranberry), and inulin (4%). Fermentation was carried out with the following strains: Lacticaseibacillus rhamnosus (LGG), Lacticaseibacillus casei (431), and Lactobacillus helveticus (R0052) at 2%. Antimicrobial activity was evaluated against pathogens including Listeria monocytogenes (strains 33423 and 33413), Staphylococcus aureus (113 and Newman), Bacillus cereus (DPC 6089), Escherichia coli (NCTC 9001), and Salmonella Enteritidis (NCTC 6676). Antioxidant capacity was measured using 2,2-Diphenyl-1-picrylhydrazylradical (DPPH) and Ferric Reducing Antioxidant Power (FRAP) assays, and angiotensin-converting enzyme (ACE) inhibitory activity was assessed. All bioactivities were found to be high in fermented whey beverage and a further significant increase was observed after simulated gastrointestinal digestion. This fruit-flavored whey beverage demonstrated notable antimicrobial and antioxidant activities, highlighting its potential for functional food applications aimed at combating harmful bacteria and oxidative stress.
