) 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.
