I am PhD student at Prof.Uwe Voelker lab in Department of Functional Genomics. My area of research is microbial functional genomics in particular analysing the whole transcriptome(by microarray and other molecular biolology methods) of B.subtilis under various stress conditions. I use QconCAT strategy for absolute quantification of carbon metabolic enzymes via MRM(multiple reaction monitoring) by LC-MS/MS. I also perofrm experiments for understanding of dynamics of SigmaB network for modelling.
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 ...

The objective of this project is an integrated understanding the metabolic, proteomic and genetic network that controls the transition from growth to glucose starvation. This transition is a fundamental ecophysiological response that serves as a scientific model for environmental signal integration and is pivotal for industrial fermentations of Bacillus that occur predominantly under nutrient starvation.

The main aim of this experiment is to actively grow B.subtilis in presense of glucose until high optical density in an aerobic fermentor and then, at a definite point of the growth, the glucose supply is shut down which leads to complete glucose exhaustion in the media. Simultaneusly samples for transcriptomics, intra and extracellular metabolomics, intra and extracellular proteomics are harvested through out the experiment.

Array hybridisation was done at Roche Nimblegen Inc. It cannot be displayed over here.
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.
