Understanding the importance of microbiomes for planetary health

14. August 2023

Cluster of Excellence "Microbiomes Drive Planetary Health"

Microbiomes Drive Planetary Health: Under this title, 30 scientists led by microbiologist Michael Wagner from the University of Vienna pool their competences. Together, they aim to understand how microbiomes – specific communities of microorganisms occupying all ecosystems, animals, plants and humans – regulate planetary health. Based on this knowledge, they intend to significantly advance the understanding of global change and solutions for a sustainable future. With their ambitious project, the team was able to succeed in the competitive excellence programme of the Austrian Science Fund (FWF).

Bacteria, archaea, viruses, fungi and protozoa are joining forces as 'microbiome': They are the foundation of the biosphere, regulate global cycles, purify water and air, influence our climate and help us with food production. Microbes live in each and every niche on and in the bodies of plants and animals. Microbial communities are also part of the human body and inhabit the gut. As such, they can prevent diseases, influence the effectiveness of drugs, regulate body weight and (jointly) control our behaviour. How exactly these tiny microbes are doing this, how they function, how they interact with each other and other organisms and how they react to disturbances has not been studied thoroughly yet.

What is the excellence initiative?

With the excellence initiative excellent=austria, Austria is opening a new chapter in basic research: Five clusters of excellence will launch cooperative projects at an unprecedented dimension at eleven locations from the summer of 2023 onwards. Researchers involved in the initiative have the opportunity to contribute outstanding research achievements in individual fields as well as in interdisciplinary areas and to firmly position this field of research at the highest international level in the long term in Austria. The University of Vienna is involved in all five Clusters of Excellence.

Seven research institutions, a joint aim – understanding the microbiome

To bridge this research gap, 30 scientists from different disciplines are cooperating in a Cluster of Excellence by the Austrian Science Fund (FWF). "We are extremely glad that we are given the opportunity to combine and further develop microbiome research and research on planetary health, two of the most important research areas of the 21st century with our endeavour," emphasises Michael Wagner, Scientific Director of the Cluster. The University of Vienna cooperates in the platform with the Austrian Institute of Technology (AIT), the Institute of Science and Technology Austria (ISTA), the Medical University of Graz, the Austrian Academy of Sciences with the Research Center for Molecular Medicine (CeMM), the TU Vienna and the Johannes Kepler University Linz. "With our Cluster of Excellence, we are creating entirely new synergies by dissolving the boundaries between red and green microbiome research in Austria and, thus, linking medicine and environmental research directly. We want to learn to understand the basic principles of microbiomes to, then, strengthen planetary health by modelling and influencing them in a targeted way," he adds.

For a sustainable future

Michael Wagner and his colleagues from the Centre for Microbiology and Environmental Systems Science at the University of Vienna have done pioneering work in Austria in the area of functional analysis of microbiomes and they have already made ground-breaking findings. In 2015, the researchers pulled off a great coup by describing the comammox bacteria for the first time ever: The discovery of these extraordinary ammonia-eating bacteria led to a change of view on the global nitrogen cycle in microbiological research. It opened up new opportunities for a more sustainable agriculture and waste water treatment.

With their task force on planetary health they are going one step further: If the scientists succeed in decrypting common basic principles of interaction and responses to disturbance in environmental and human microbiomes, we can more accurately predict global change and influence microbiomes in a targeted way at the same time, serving both human and planetary health. "This is indispensable for navigating our Earth towards a more sustainable future," says Michael Wagner.
