The aim of this project is to develop a detailed kinetic model of the CcpA-dependent regulatory network, the key regulon of flux regulation in B. subtilis. Thereby involved are more than 300 genes e.g. catabolism, overflow metabolism, the TCA cycle and amino acid anabolism which are regulated via carbon catabolite regulation (CCR)
Basically extending SYSMO-LAB 1st phase into second with addition of fourth species, Lb. plantarum. The main focus is amino acid metabolism. primary metabolisms, like glycolysis is also interest.

The Sulfolobus systems biology (‘‘SulfoSYS’’)-project represented the first (hyper-)thermophilic Systems Biology project, funded within the European trans-national research initiative ‘‘Systems Biology of Microorganisms’’. Within the SulfoSYS-project, focus lies on studying the effect of temperature variation on the central carbohydrate metabolism (CCM) of S. solfataricus that is characterized by the branched Entner–Doudoroff (ED)-like pathway for sugar (glucose, galactose) degradation and the ...

The electron transport chain of E. coli is branched. Different NAD Dehydrogenases and terminal oxidases are known to be expressed at different oxygen availabilities. By deleting multiple genes mutant strains were constructed that posses a linear electron transport chain. These mutants were investigated in continous bioreactor experiments with limiting glucose and varying oxygen supply.

Cultures grown under standard SUMO conditions were analyzed with respect to heterogeneity in gene expression. To this end GFP reporter strains were constructed and GFP expression at single cell level was monitored by flow cytometry.
In Escherichia coli several systems are known to transport glucose into the cytoplasm. A series of mutant strains were constructed, which lack one or more of these uptake systems. These were analyzed in aerobic and anaerobic batch cultures, as well as glucose limited continuous cultivations.
