- Dairy origin:
- Isolated from milk of different animal species
- Dairy origin:
- Infant feces
- Breast milk
Preservation method: -80 °C
Information management: Not specified
- Technological application
- Microbiological safety
- Production of natural antimicrobial compounds (bacteriocins and reuterin)
- Probiotic potential for their use in food
- Some of the strains of interest (4 lactococci, 4 lactobacilli, 2 enterococci and one bifidobacterium) are labeled by fluorescence to allow its monitoring in food
Transference of the material to interested research groups by signature of the correspondent MTA.
The strains are also available to companies, under transference and/or license contracts.
Key words: Lactic bacteria, bifidobacteria, bacteriocins, reuterin, starter cultures, probiotics, dairy products
Summary: The collection of microorganisms has been created during the development of the following research lines:
- Improvement of the microbiological safety of food through biological inhibitory systems
- Bacteriocin-producing lactic bacteria and extracellular enzyme-producing bacteria in cheese maturation
- Characterization and development of autochthonous ferments, in order to alleviate the imbalances in the bacterial groups present in raw milk
- Isolation and characterization of bacteria of human origin with probiotic and technological properties
Brief historical review
- Collection of more than 1000 microorganisms of dairy origin (milk isolates from different animal species and Spanish cheeses) started more than 30 years ago.
- Collection of more than 600 bacteria of human origin (isolated from infant feces and breast milk) started in 2000.
