Mechanism of water extraction from gypsum rock by desert colonizing microorganisms

Abstract

This research provides an in-depth analysis of how microorganisms are able to survive in the world’s driest non-polar place, the Atacama Desert, Chile. We show that these organisms extract water from gypsum rocks in this desert, enabling these colonizing microorganisms to sustain life in this extreme environment. We believe the results in this work could not only shed light on how microorganisms can obtain water under severe xeric conditions, but also provide insights into potential life in even more extreme environments, such as Mars, as well as offer strategies for advanced water storage methods.
