Escherichia coli reagiert auf schädliche Umweltreize, wie z.B. Hitzeschock, mit der verstärkten Expression von Stressproteinen, die den Auswirkungen schädlicher Umweltbedingungen auf die Faltung und Funktion der zellulären Proteine entgegenwirken. Transkriptionelle Induktion der Stressgene wird z. B. über alternative Sigma-Untereinheiten der RNA Polymerase erreicht. Basierend auf der Tatsache dass viele Stressproteine auch unter normalen Wachstumsbedingungen essentiell sind wurde in dieser Arbeit die Regulation von Stressgenen während eines Wachstumszyklus von E. coli in geschlossenen Kultur untersucht. Es konnte gezeigt werden, dass die sigma32 abhängige cytoplasmatische Stressantwort während des Wachstums oszilliert mit einer Aktivierung ...
