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.
