SPRUCE BARK POLYPHENOLS AS METABOLIC BOOSIERS FOR YEAST DEVELOPMENT

摘要

The present study has aimed to investigate the influence of anthocyanidins extracted from spruce bark (Picea abies) on the development of Saccharomyces cerevisiae yeast. The biostimulatory effect follows the so-called dose-effect relationship. At a concentration of 400 mg/L bioactive product, the yield in the substrate increases by 16% with an increase in protein biomass of approximately 80%. These results are encouraging, if the possibilities of developing larger scale applications in terms of protein production are considered.
