Beschreibung
Zusammenfassung:	Disclosed is a method of development and selection of baker's yeast strains that can exhibit high raising activity in sweet and/or lean dough in the bakery and pastry industries. The method includes the steps of: (i) developing the baker's yeast strain, preferably with the process of multiple crossing, by using the combination of one or more than one of the mutagenesis, evolutionary engineering, asexual hybridization, recombinant DNA technology and sexual hybridization methods; (ii) preparing the synthetic or flour-based selective nutrient medium, preferably the synthetic nutrient medium having a sugar content of 0%, 15% and/or 25%, and incubating the strains developed in multiple well plates inside the nutrient medium prepared; (iii) scanning the strains incubated by using a high-resolution optical scanner, or by the naked eye or a device with a spectrophotometric reader, preferably by using a high-resolution optical scanner, and selecting the strains that perform the best acidification.
