Fodder (Candida maltosa) and baker (Saccharomyces cerevisiae) yeasts using for biologically active glycans obtaining have been studied. The isolated glycans contained homopolysaccharides mannans and glycans. The enzyme- (yield 14%) and autolysates (yield 8,5%) appeared to be perspective for obtaining the biologically active polysaccharides. The intact cells of baker yeasts were less suitable (yield of extracted glucan using the proposed technology was 7,2%). The isolated glycans contained 75–94% of active element and showed the marked inhibiting effect against the tobacco mosaic virus infectiveness and Agrobacterium tumefaciens induction of tumours in the explants of potatoes tubers parenchime. The glycan preparations stimulated germinating power, energy of seeds sprouting, growth and development of tomatoes and tobacco. They may be used in elaboration of complex biopreparations intended for control of virus and bacterial diseases of agricultural plants and in medicine.

Key words: yeasts, Candida maltosa, Saccharomyces cerevisiae, glycans, biological activity, tobacco mosaic virus, Agrobacterium tumefaciens, tobacco, tomatoes, potato.
