Antibiotics are made during the second phase of growth when there is a transition in metabolism from primary to secondary metabolism. Primary metabolism is growth related and involves all the normal cellular activities associated with cell growth and division. Whereas secondary metabolism is non-growth linked and is non-essential but many important activities occur during this phase which help the bacterium survive.
One of these activities is antibiotic production and is widespread in streptomycetes ...

The aims of this investigation is to quantify metabolites associated with pathways involved in stress responses for parameterising models of oxidative stress metabolism; the measurement of metabolic fluxes of metabolites of interest with intracellular concentrations

A further investigation of the variation of FNR number in E.coli Cyo/Cyd mutants is carrying out at different oxygen supply levels. The agent-based FNR and ArcBA model is going to be used for this prediction. The number of Cyo or Cyd and other unrelated agents would be set as ‘0’ at the initial XML file with which the model starts. According to the restrictions of supercomputer ‘Iceberg’ (serviced provided by the University of Sheffield), certain parameters, such as memory per node, would be ...
A key insight, emerging from discussions and data between the projects PIs, was the importance of switching rates in bistable systems. While the existence of multiple steady states in bistable systems can be described by universal models (that do not differ between different systems), switching rates from one stable state to another depend on the molecular details of the system under consideration.
