Impact of a Saccharin Higher Homolog on Saccharomyces cerevisiae

Saccharin is an organic compound, which is often used as a calorie-free artificial sweetener. It salts are being produced for the market for over 80 years. Saccharin and its derivates are very applicatory oriented, therefore researchers synthesize more and more active ingredients, which could potentially show better performance. This work considers the effect of biological activity of a newly synthesized saccharin derivative Me- thyl 4-hydroxy-1,1-dioxo-2H-1,2-benzothiazine-3-carboxylate (6Sac) on yeast Saccharomyces cere-visiae. Qualitative comparison of the studied activity with the activity of the saccharine sodium salt is presented. Our results were gained by two different ways of viability detection: counting dead/live cells dyed with methylene blue and counting colony-forming units (CFU). The study has shown that the saccharine derivative with an ester functional group has negative effect on growth and repro-duction of yeast. The qualitative comparison of the activity of the tested substance with the already known activity of saccharine sodium salt is a convenient method for following the model organism Saccharomyces cerevisiae.
