5. Brewing

??? • Introducing new Saccharomyces cerevisiae strain (Y190 strain) from Schwab lab for Y2H o Aim of the experiment: The Y190 Saccharomyces cerevisiae is a special strain for Yeast-two-hybrid. This strain carries a Gal4 and Gal80 deletion to higher the signal/noise-ratio of protein-protein interactions. Reporter for protein-protein interactions are HIS3, lacZ and MEL1 and are encoded in the genomic DNA. Transformation markers are trp1, leu2 and cyhR2 and are encoded on the transformation plasmids. • Inoculation of YPD medium with S. cerevisiae and brewing yeast strain 34/70 (part 2/3) o Aim of the experiment: Discrimination of growing ability in wort medium. • Electroporation of electrocompetent E. coli with P698+699
