Jena, July 21, 2026 – A research team led by Prof. Dr. Kirsten Küsel at the Friedrich-Schiller-Universität Jena has gained new insights into the adaptability of microorganisms in groundwater. In the journal Nature Microbiology, they presented the concept of “microbial frugality.”

How microbes survive at the limit
The concept describes how microorganisms persist in deep rock pores and aquifers under extreme nutrient deficiency. Through evolutionary adaptations, they reduce their energy consumption to a minimum and enter a standby state. This allows them to maintain central metabolic cycles even with minimal resource supply.
Significance for climate protection and water quality
Groundwater is one of the world’s most important sources of drinking water. The research from Jena shows that the microbes residing there contribute significantly to chemical stability and the regulation of climate-relevant gases such as methane or nitrogen compounds. Protecting these hidden ecosystems is therefore directly linked to the security of our drinking water supply.
Background: Research at the Cluster of Excellence
The Jena Cluster of Excellence “Balance of the Microverse” investigates the complex interactions of microbial communities. The scientific work in Jena underscores the city’s role as an international center for microbiology and fundamental ecological research, which has significance for global climate protection far beyond regional borders.
