Microbial Stress Banner

For the 6th time the European Federation of Biotechnology organizes the 3-days meeting on microbial responses to stress with a program that covers both fundamental and applied aspects.
The meeting welcomes, amongst others, microbiologists, biotechnologists, system biologists, biochemists, and molecular biologists from both the academic and industrial sectors.
As a satellite event to this meeting the COST action EuroMicropH will organize a 2 days Open Meeting (18-19 September 2023), which will share a joint session with the EFB Microbial Stress meeting at the same venue.


Over time microorganisms developed different molecular mechanism to sense, respond and adapt to stress conditions. These mechanisms can drive gene expression and provoke changes in protein composition, metabolism, morphology and physiology. Which molecular mechanisms exist to sense stresses? How are signals conveyed within a cell or a microbial community? Which cellular responses are triggered? Which possibilities to analyze the stress response exist?
Synthesis of value-added products at levels relevant for industrial production often requires microorganisms to perform at conditions different to optimal physiological conditions or is even triggered under these conditions. Stress in this context includes but is not limited to physical (pH, temperature, aeration), chemical (high substrate and product concentrations), and metabolic (carbon, energy and redox) parameters. How can stress responses be mitigated or exploited in a bioproduction environment? Which implication does it have for strain design?
Microbial life can be found in almost all ecosystems on Earth. Various biotic and abiotic stresses serve as evolutionary drivers. Harsh conditions associated to these ecosystems include high or low temperatures, salt stress, high or low pH, etc. have triggered the development of specialized microorganisms referred to as extremophiles. These organisms display a broad range of sophisticated mechanisms to deal with the challenges of ecological niches. Which evolutionary drivers shape microbial life?
Soil is a complex, heterogenous habitat, which is important for plant growth and performance. Agricultural practice depends on the soil composition and performance, which is significantly influenced by microorganisms. Changing climatic conditions, agricultural practices and the input of man-made substances lead to changing stresses that affect microorganisms.
Human cells are in direct contact with multiple microbial communities primarily via intestine and skin. Lifestyle, nutrition and diseases are some of the environmental factors influencing and changing the interactions between microbes and the host organism. Which stress mechanisms are associated to this complex network of interactions?
