[Biotherapeutic use of yeasts--importance of probiotic products].

Besides their important biotechnological and industrial applications, yeasts have been used during the last years, in obtaining probiotic products, along with lactic acid bacteria and various enzymes. Our study deals with some aspects regarding the use of yeasts as animal and human probiotics, and their possible mechanisms of action. Also, we present information on probiotic products synthesized by international and national companies. Finally, there are described future prospective of research concerning the applications of recombinant yeast strains as basis for obtaining new bio-drugs. In conclusion, the data comprised in this paper, presents an interesting argument for using yeasts as biotherapeutic agents, an alternative to conventional treatments.
