Key words:

filamentous fungi, yeasts, bacteria, University of Extremadura, Food Hygiene and Safety


It is a small collection that the Food Hygiene and Safety group of the University of Extremadura has been making throughout its journey, from strains obtained from doctoral theses and from the projects of the group. We have a wide variety of filamentous fungi, mostly from meat products.

Brief historical review

Since 1992 we began to isolate and identify different microbial strains from meat products. The first ones (molds and yeasts) come from Iberian hams. Lately we are also isolating bacterial strains from milk and sheep cheeses, along with those of meat products with which we continue to work.
