Project description:In this study we investigate the molecular physiology of the main S. cerevisiae commercial strain (PE-2) used on Brazilian bioethanol process under two distinct conditions: typical (TF) and flocculated (co-aggregated - FL) fermentation. Transcriptional machinery of PE-2 was assessed by high throughput sequencing-based methods (RNA-seq) during industrial fed-batch fermentations. Data from comparative analysis revealed distinct transcriptional profiles among conditions, characterized mainly by a deep gene repression on FL process.
Project description:We observed through Western blot that Mycobacterium marinum secreted more highly abundant PE-PGRS proteins that are above 130 kDa when treated with compound 36 than mock-treated bacteria. We would like to explore which PE-PGRS proteins are more secreted in this condition and whether other proteins are also differentially secreted between two conditions.

Data from comparative analysis revealed distinct transcriptional profiles among conditions, characterized mainly by a deep gene repression on FL process. We investigated the transcriptional changes in S. cerevisiae PE-2 strain under industrial fermentation conditions using RNA-seq protocols. We analyzed 13 fermentation time-points where 6 time-points on typical fermentation conditions (TF) and 7 time-points on flocculate conditions(FL). The raw data have been submitted to SRA as SRP014755
