COMPARATIVE STUDIES ON INVERTASE ACTIVITY IN STRAINS OF GENUS SACCHAROMYCES YEAST IMMOBILIZED SODIUM ALGINATE

The comparative analysis of yeast strains, immobilized in sodium alginate and not immobilized (cellular density 2,74 x 10 6 ) shows the same pattern for all three strains . In the first 20 minutes, the invertase activity of the immobilized cells represents roughly 50% of all not immobilized cell activity, the differences are significant. For the determination after 30 minutes, the enzyme activity difference stays insignificant for Cross Evolution (-0,02850 Nm fructose), minus distinctly significant for Lallvin QA 23 (-0,2675 Nm reducing sugar) and minus very significant for Ancor (-0,3919 mM reducing sugar).
