Es produziert für uns Insulin und viele weitere pharmazeutisch wichtige Stoffe. Normalerweise fühlt sich das Bakterium bei 37° Celsius am wohlsten. Höhere Temperaturen verursachen dem kleinen Organismus Stress, Temperaturen über 46° Celsius sind bereits tödlich. Wissenschaftler der Technischen Universität München (TUM) haben nun an E. coli Bakterien untersucht, wie sich Organismen durch Evolution an höhere Temperaturen anpassen.
