Glucose pulsed L. lactis

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 ...

Comparative Systems Biology: Lactic Acid Bacteria

Challenge: Comparative analyses, as demonstrated by comparative genomics and bioinformatics, are extremely powerful for (i) transfer of information from (experimentally) well-studied organisms to the other organisms, and (ii) when coupled to functional and phenotypic information, insight in the relative importance of components to the observed differences and simalities. The central principle of this proposal is that important aspects of the functional differences between organisms derive not ...

The two lactic acid bacteria L. lactis and S. pyogenes were studied with respect to the concentration of intracellular metabolites involved in glycolysis in time upon a glucose pulse. Models that describe this behavior are also constructed

L. lactis was grown in rich THY medium, strongly concentrated and glucose-pulsed in a MES buffer. Intracellular metabolite concentration is followed in time.

In this experiment we glucose-pulsed an L. lactiss cultures re-suspended in 100 mM MES buffer at pH 6.5. Samples were taken in time to study intra- and extracellular metabolites. These data are used to construct a kinetic model of the catabolism of E. L. lactis

Glucose pulsed L. lactis with 20 mM glucose in 100 mM MES buffer at pH 6.5 and followed intracellular metabolites in time

L. lactis was grown in LAB medium, strongly concentrated and glucose-pulsed in a MES buffer. Intracellular metabolite concentration is followed in time.
