Transcriptome data for chemostat cultivated samples

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".

The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.

Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

BaCell-SysMO 2 Modelling carbon core metabolism in Bacillus subtilis – Exploring the contribution of protein complexes in core carbon and nitrogen metabolism.

Bacillus subtilis is a prime model organism for systems biology approaches because it is one of the most advanced models for functional genomics. Furthermore, comprehensive information on cell and molecular biology, physiology and genetics is available and the European Bacillus community (BACELL) has a well-established reputation for applying ...

High salinity chemostat cultivation, multiomics sampling (proteome, transcriptome, metabolome, fluxome) and modelling of carbon core metabolism of Bacillus subtilis 168.

B. subtilis was grown in minimal media in a chemostat at different growth rates (µ= max, µ=0.1, µ=0.4) and in the presence of 1.2M NaCl (µ=0.1) with or without glycinebetaine. Transcriptome, proteome and metabolome were investigated.

The reverse transcriptase synthesizes DNA, which complements the mRNA template (complementary DNA, cDNA). Cy3/Cy5-dCTP are incorporated into cDNA during Reverse transcription. The obtained Cy3/Cy5 cDNA are then competitively hybridised onto Agilent microarray slide and subsequently scanned.

Cells were harvested from culture keeping the cells cold to quench the physiological condition of RNA and the cells were mechanically disrupted. RNA was isolated from the cells by conventional acid-phenol method and the quality was checked by Agilent bioanalyser.
