The paper’s aim is to emphasize the variety of the yeasts populations which are present in the musts from inland and Tokaj areas. The study is based on the alcoholic fermentation on the four strains which were selected for this purpose, the isolation of the specific yeasts and the quantification of the obtained results through in the data base. From the fermentative dynamics’ point of view, the differences occur depending on the growing environment and on the strain types which were considered.The minerals play an important role in increasing the biotechnological properties of the wine yeasts Saccharomyces bayanus, Saccharomyces ellipsoideus regarding the fermentative activity and multiplication speed.
