Quantitative analysis of bacterial growth and starvation at elevated temperatures — •Mariel García Huiman, Severin Schink, Michael Szabo, and Ulrich Gerland — Technical University of Munich, Physics Department, James-Franck-Str. 1. 85748 Garching

Up to now, the temperature dependence of bacterial behavior regarding growth and viability beyond the physiological temperature is poorly understood. We study the effects of temperature stress on E.coli in minimal nutritional environments. At highly elevated temperatures, short-term starvation causes genetically homogeneous bacterial populations to split into two distinct subpopulations, growing and non-growing. This plays a role in bacterial persistence.
