Modelling bacterial Quorum sensing and effects of nutrient availability
Absztrakt:
Many
bacteria developed a possibility to recognise aspects of their
environment or to communicate with each other by chemical signals. The
so-called Quorum sensing (QS) is a special case for such a
communication, a regulatory system for gene expression. Nutrient
availability does not only influence bacterial growth but also the gene
regulatory system for QS. Further effects which cause e.g. detachment
processes and heterogeneous behaviour within colonies appear. From a
mathematical point of view, ODE, PDE and stochastic approaches are used
to describe and analyse the qualitative behaviour of bacterial quorum
sensing systems.
