Seit 1871 gewährleistet die BAM Sicherheit in Technik und Chemie und schafft so Vertrauen in Innovationen und Zukunftstechnologien. Mit unserer Arbeit tragen wir dazu bei, den Wirtschaftsstandort Deutschland zu stärken und auf gesellschaftliche Herausforderungen wie die Energiewende oder den Klimawandel zu antworten.

Im Rahmen der Vortragsreihe „Wissenschaft mit Wirkung“ hat die BAM führende Köpfe aus der Wissenschaft eingeladen, um die Entwicklungen der BAM in den Themenfeldern und die Wirkung von Wissenschaft für die Gesellschaft gemeinsam zu beleuchten. Sie sind herzlich zur Teilnahme an den virtuellen Vorträgen eingeladen.

SummaryMost habitats on Earth are characterized by extreme environmental conditions. All these environments are at the edge of habitability and range from equatorial to polar regions, from marine to terrestrial environments and from surface to deep subsurface ecosystems. Environmental niches in extreme environments are in general characterized by extraordinarily hot, cold, acidic, alkaline or dry conditions, or are subjected to high salinity, radiation or pressure. Desert soils, for example, are characterized by extreme heat during the day and very low temperatures at night. In addition, there is a lack of water and nutrients, as well as high salt content and high UV radiation. In this lecture multiple examples will be given illustrating that a large number of different microorganisms can be found in such habitats, despite the extreme conditions. These microorganisms – called extremophiles - have adapted perfectly and are therefore able to colonize virtually any niche on Earth - no matter how hostile it may appear – as long as it is not too hot. Geomicrobiologists want to understand the structure and function of microbial communities in extreme environments, their life strategies and adaptation mechanisms as well as their reaction to changing environmental conditions. Finally, extremophiles are also useful model organisms to learn more about potential life beyond Earth.

This lecture ist part of the LECTURE SERIES Microbes and Environmental Chemistry 14.10. - 18.11.2021. Join us for a virtual trip around the world: on six Thursdays from 14 October to 18 November, always from 4 to 6pm. Six renowned international scientists will share their ground-breaking observations of processes on this planet. The spotlight is on interactions of living organisms and landscapes /materials as mediators of global change in all regions of the Earth.
