Comparison of the response to bile of Lactobacillus casei BL23 and its derivative strain TC01

ABSTRACT: The response to bile of Lactobacillus casei BL23 and its derivative strain TC01 was investigated. TC01 strain carries a complete deletion of gene LCABL_02080 which encodes a two component signal transduction response regulator. Lactobacillus casei BL23 and TC01 strains were grown in MRS medium at 37C without shaking until O.D. 595 nm. reached 0.5. The cultures were then two fold diluted with prewarmed MRS medium (control) or MRS supplemented with 0.2% bovine bile (treatment) and incubation continued for 45 min. Cells were then harvested and total RNA purified.

Hybrid wine yeast strains

Project description:This experiment is the analysis of the transcriptomes of several hybrid yeast strains obtained by crossing natural (from wine) isolates of S. cerevisiae and S. uvarum. All isolations have been done from hybrid strains growing in exponential phase in YPD. Keywords: Strain comparison Transcriptomic analysis of three independent replicates of each yeast strain growing in exponential phase. Each replicate has been hybridized on a different macroarray (F19-F22-F24) as indicated in the sample files. A single DNA (S. cerevisiae 3002 wine strain) genomic hybridization, from the same labeling reaction, was done on the same macroarrays for normalization.

Recovered Fermentation

Project description:Gene expression analysis of a time course experiment of a synthetic must (nitrogen-poor) fermentation by a natural wine yeast, supplemented at 72 hours with 200 mg/l of nitrogen Three replicates of five time points taken at 24, 48, 80, 96 and 144 hours after yeast inoculation. Time points 24 and 48 hours are common to Sluggish fermentation. Time points at 80, 96 and 144 hours are exclusive of this experiment.

Normal, sluggish and recovered fermentation

Project description:Gene expression analysis of time course experiment of [1] a synthetic must (nitrogen-rich) fermentation by a natural wine yeast; [2] a synthetic must (nitrogen-poor) fermentation by a natural wine yeast; and [3] a synthetic must (nitrogen-poor) fermentation by a natural wine yeast, supplemented at 72 hours with 200 mg/l of nitrogen. This SuperSeries is composed of the following subset Series: GSE5835: Normal Fermentation GSE5836: Sluggish Fermentation GSE5837: Recovered Fermentation Keywords: SuperSeries Refer to individual Series, and to genomic hybridization of the individual membranes used for normalizing single samples.
