Bottom-fermenting Saccharomyces pastorianus strains driving brewing fermentation processes are usually reused several times. It is still unclear, whether the number of successions may have an impact on cell physiology prompting consequences for brewing quality. In this study, fermentation performance of up to twenty consecutive runs in a brewery was investigated. For each run mRNA expression levels of cellular marker molecules, which are known to correlate with metabolism, hexose transport, agin ...[more]

Comparison between all runs of industrial serial repitching 1

Project description:The aim of this study was to identify differently expressed genes between all runs of four serial repitchings from a German brewery. In the brewery the number of successive runs varied from 17 to 20. 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 four loops are summarized in this study. The samples were taken from four serial repitchings of a German brewery (brewery A). Microarrays were hybridized in a loop approach.

Comparison between all runs of a serial repitching in brewery A

Project description: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.

Comparison between a first and a last run of industrial serial repitching

Project description:The aim of this study was to identify differently expressed genes between first and last runs of serial repitchings from four different German breweries. In the breweries the number of successive runs varied from 4 to 22. 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 eight microarrays are summarized in this study. The samples were taken from four German breweries. Microarrays were hybridized in a dye swap approach: Dye-swap 1: brewery A runs 1 vs. 22; Dye-swap 2: brewery B runs 1 vs. 5; Dye-swap 3: brewery C runs 1 vs. 4; Dye-swap 4: brewery D runs 1 vs. 8

Comparison between Saccharomyces cerevisiae HS 10, HS 34 and HS 12, HS 37

Project description:Gene expression of different flocculent (HS 10 and HS 34) and powdery (HS 12 and HS 37) yeast strains compared to each other during exponential and stationary growth phase was analysed. The isolation of RNA was done by disruption of the cells under liquid nitrogen using mortar and pistil and then the Qiagen RNeasy Midi Kit with some modifications within the manufacturers´ protocol and the Qiagen RNase-Free DNase Set were applied. 6 µg of the total RNA per sample was used for each microarray experiments. The indirect labelling by the tyramide-signal-amplification method (MicromaxTM TSATM labelling and detection Kit from Perkin Elmer life sciences) was used to increase the Cy3 and Cy5 signals of microarray detection. Each cDNA containing Biotin- and Fluorescein-nucleotides respectively was purified with a QIAquick PCR purification kit and suspended in 11 µl of the formamide containing hybridization buffer. The slides were hybridized at 42°C over night under a cover slip. The microarrays were scanned by the Axon 4000B scanner; image intensity data were extracted and analysed with GenePix® Pro 6.0 software. Data from different scans of Dye-swap experiment were extracted by GenePix Pro 6.0 software, normalized and united. An outliertest has been applied in order to find outliers amongst the gene replicats. Subsequently, a t-test (1% and 5% probability of error) has been used in order to find regulated genes. Keywords: sorted yeast cells Microarray experiments were realised with dye swap.

Comparison between stationary phase S. cerevisiae H155 cells, exponential phase cells and stressed cells

Project description:The sensibility of the used low-density arrays was tested by applying the lab strain S. cerevisiae H155. Important abiotic parameters were tested as they were introduced as elevated osmotic, pH or ethanol stress to the cells. Results from one loop including samples from cells in five different conditions are summarized in this study. Microarrays were hybridized in a loop approach.

Investigation of colominic acid effects on immortalized Schwann cells

Project description:The purpose of the present study is to influence of CA coating on immortalized Schwann cells in vitro in comparison to standard culture conditions as well as to laminin as a positive standard. CA is a homopolymer of polysialic acid (PSA), which has â attached to the neuronal cell adhesion molecule (NCAM) â emerged as particulate attractive candidate for promoting morphological plasticity of axonal processes during axonal path finding and activity-dependent remodelling. For this purpose self-spotted microarrays with 352 neurospecific genes were hybridized with mRNA from immortalized Schwann cells cultivated on different coating conditions: In order to enable a comprehensive comparison to the established coating material laminin as well as to standard coating conditions (cultivation on the cell culture surface) a loop-design has been chosen, which is based on the dye-swap design and facilitates a direct comparison of the different states. Results from 3 microarrays are summarized in this study. The samples originate from different coatings. Microarrays were hybridized in a loop design with one common reference using a dye swap approach.
