[Influence of plant extracts on the metabolic activity of the yeast Saccharomyces cerevisiae 39]. / Vliianie nekotorykh rastitel'nykh ékstraktov na metabolicheskuiu aktivnost' drozhzhei Saccharomyces cerevisiae 39.

Addition to the nutrient medium of the extracts of camomile, nettle, mint, or Saint-John's-wort to a concentration of 0.5-4% was established to activate the yeast growth. The maximum effect was recorded on the addition of the extracts to the poor "water" medium. The extracts of camomile and Saint-John's-wort were shown to inhibit the alcohol dehydrogenase activity of the yeast cells, whereas the extracts of nettle and mint increased the activity of this enzyme by 62-70%.
