Acetate-ester hydrolase activity for screening of the variation in acetate ester yield of Cyberlindnera fabianii, Pichia kudriavzevii and Saccharomyces cerevisiae

Esters constitute an important class of aroma compounds and contribute significantly to the aroma of yeast-fermented beverages. Ester formation is well studied in Saccharomyces cerevisiae, while production of aroma compounds by non-conventional yeasts has received little attention. The selection of such strains for co-culturing with S. cerevisiae offers opportunities for product innovations. Therefore, we performed a comparative analysis of the...
