Comparison between all runs of a serial repitching in brewery A

ABSTRACT: The aim of this study was to identify differently expressed genes between all 6 runs of brewery A. A run describes the industrial fermentation of brewery wort. By the end of fermentation the yeast slurry is cropped. These cells are reused for inoculation of another cylindro-conical vessel (CCVs). Results from two loops of two different breweries are summarized in this study. The samples were taken from two serial repitchings of a two breweries. Microarrays were hybridized in a loop approach.

Serial repitching of brewing yeast inoculates is an important economic factor in the brewing industry, as their propagation is time and resource intensive. Here, we investigated whether replicative aging and/or the population distribution status changed during serial repitching in three different breweries with the same brewing yeast strain but different abiotic backgrounds and repitching regimes with varying numbers of reuses. Next to bud scar numbers the DNA content of the Saccharomyces pastor  ...[more]
