Key words:probiotics, functional cultures Summary:General objective: contribute to the generation of knowledge about the functions performed by beneficial intestinal microorganisms and those present in food in relation to human health.Current Research Lines-Line 1. Functionality of microorganisms and probiotic foods.-Line 2. Interactions of intestinal microorganisms with the host and with technological challenges.-Line 3. Obtaining, preserving, and cultivating fecal microbiota-Line 4. The microbiota in different physiological and pathological states: dysbiosis, microbial markers of disease and strategies to modulate the microbiota.-Line 5. Bioinformatics tools for the study of the functionality of microbiota and probiotics.
Brief historical review
The group's bacteria collection began in 2016 as part of several projects funded in public research calls. The collection is constantly growing and we are currently including isolates of food origin
