Brief historical review
The bacteria collection has been generated from research projects funded between 1999 and 2014 by 8 national projects (FEDER, CICYT, PETRI, CONSOLIDER), 7 autonomous (PROMETEO, CSGVA, GVACOMP) and one European "Microbiota of Andean Food: tradition for healthy products "(FP7-PEOPLE-2009-IRSES-nº 247650).
