Use of Schizosaccharomyces pombe to produce stable pigments during red winemaking

This work has studied the production of stable pyranoanthocyanin pigments during fermentation using S. pombe and Saccharomyces cerevisiae. Along the fermentation, anthocyanins were determined by HPLC-DAD/MS, acetaldehyde was measured using GC-FID and pyruvic acid was quantified by enzymatic tests. Results show that S. pombe strains produce higher amounts of pyruvic acid, and therefore also of vitisin A, than Saccharomyces controls.
