Project description:Helicobacter cinaedi is an emerging bacterial pathogen of immunosuppressed individuals. The species is traditionally thought to require an H2-enhanced microaerobic atmosphere for growth, although it can proliferate under aerobic conditions when co-cultured with epithelial monolayers or supplemented with certain metabolites (notably, L-lactate). The goal of this experiment was to assess the global transcription changes that occur in the H. cinaedi type strain (ATCC BAA-847) under various media and atmospheric conditions. These include bacterial monoculture, as well as co-culture with Caco-2 intestinal epithelial cells. In total, Illumina mRNA-seq (stranded, paired-end) was performed on H. cinaedi grown under 9 in vitro culture conditions (4-5 biologic replicates per condition).

A proteome reference map of the wine lactic acid bacterium Oenococcus oeni ATCC BAA-1163

Project description:Oenococcus oeni is the main lactic acid bacterium that carries out the malolactic fermentation in virtually all red wines and in some white and sparkling wines. O. oeni possesses an array of metabolic activities which can modify the taste and aromatic properties of wine. There is therefore industrial interest in the proteins involved in these metabolic pathways and related transport systems of this bacterium. In this work, we report the characterization of the O. oeni ATCC BAA-1163 proteome. Total and membrane protein preparations from O. oeni were standardized and analyzed by two-dimensional gel electrophoresis. Using tandem mass spectrometry we identified 226 different polypeptides corresponding to 155 unique proteins, which have been classified by their putative function and subjected to bioinformatics analysis.
