13C Metabolic Flux Analysis of Bacillus subtilis 168 in continuous high-salinity culture
- Comparison of metabolic flux distribution in carbon core metabolism (EMP, PPP, TCA) of Bacillus subtilis under 3 different conditions: "salt-free" reference, "stress" chemostat, "osmoprotected" chemostat.
- Model created using OpenFLUX and Microsoft Excel
- Model computed using MatLAB

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

Snapshots: No snapshots
3 chemostat experiments:
each in 4 biological replicates incl. 1 fed with labelled glucose
T = 37°C
pH = 7.1
V_R = 300 mL (dasgip parallel bioreactor system)
V_G = 9 sL/h (0.5 vvm)
M9 Minimal medium + 3,4-dihydroxybenzoate (chelating agent) + 1g/L Glucose
n = 1000 rpm
3 conditions:
"reference" without additional sodium chloride as control
"stress" supplemented with 1.2M sodium chloride
"osmoprotection" supplemented with 1.2M sodium chloride and 1mM glycine betaine (osmoprotectant)
