Among the many topics discussed during the Scientific Retreat MAGI in Precision Medicine and Omics Sciences at Villa Hoffmann in Merano, particular attention was devoted to the mid-week sessions on circular bioeconomy and endocrine health. These sessions brought into dialogue specialists in biotechnology, environmental science and endocrinology, and offered a framework in which possible connections between industrial innovation and human reproductive health could be examined and critically discussed.
During the session dedicated to circular bioeconomy, Prof. Iza Radecka and Dr Fidelin Tuchenbou-Magaia from the Faculty of Biotechnology at the University of Wolverhampton presented ongoing and planned work on bacterial biopolymers, in close interaction with MAGI researchers and the multi-omics and modelling teams. Their research explores the possibility of producing biodegradable polymers from bacteria using industrial food-processing waste as the primary substrate. In this scenario, materials that would otherwise be discarded might be converted into biopolymers that, in specific applications, could complement or partially replace traditional petroleum-based plastics. The project therefore sits at the intersection of environmental protection, microbiology and circular economy, and resonated with several other contributions at the retreat devoted to sustainability and public health.
Within this emerging collaborative framework, MAGI is envisaged as playing a twofold role. First, researchers from the institute’s modelling and data-science groups are exploring computational tools that could support the potential scale-up of the bioprocess. Mathematical and statistical models are being developed and tested to describe the dynamics of microbial growth, substrate utilisation and polymer synthesis in bioreactors, with the long-term aim of assessing whether such tools might help maintain stable and efficient production under industrial conditions. These models integrate kinetic parameters, metabolomic readouts and systems-biology concepts, and are being evaluated for their capacity to improve predictability, limit energy and resource waste and inform the design of possible future pilot plants.
Second, MAGI’s genomics, metabolomics and proteomics platforms offer high-resolution multi-omics profiling of microbial strains with putative polymer-producing potential. Because a large number of bacterial species and variants can in principle synthesise biopolymers, systematic selection is essential. By combining genome sequencing, metabolic fingerprints and proteomic characterisation, MAGI scientists aim to help identify strains that appear to offer a favourable balance between yield, robustness and environmental impact, while documenting their properties in a transparent and reproducible manner. This integrated approach is expected to support more rational strain-selection strategies, complementing empirical screening rather than replacing it.
During the discussions in Merano, participants also considered the possibility of developing a joint Marie Skłodowska-Curie Fellowship proposal or similar European training initiatives in the future. At this stage, these ideas remain under evaluation, and the retreat served primarily as a venue to exchange views on potential scientific aims, training components and institutional roles, without committing to a specific funding scheme or timeline.
A complementary line of reflection emerged in the sessions devoted to endocrinology and reproductive health, coordinated together with Prof. Aldo Calogero and Dr Rossella Cannarella. Here the focus shifted from industrial waste streams to environmental contaminants, in particular endocrine-disrupting chemicals (EDCs) such as bisphenol A (BPA) and organotin compounds. Over recent decades, several clinical and epidemiological studies have suggested a decline in sperm counts and qualitative alterations in semen parameters among men of reproductive age, although the extent and causes of these trends remain under active debate. While Mendelian genetic forms of male infertility account for a well-defined subset of cases, increasing attention is being paid to the possible contribution of chronic exposure to EDCs in everyday life.
Building on these observations, MAGI and its partners outlined a prospective programme that could combine several complementary components. Targeted mass-spectrometry measurements are being considered to quantify selected contaminants in biological samples and in relevant environmental matrices. Detailed clinical and instrumental assessments from collaborating endocrinology and andrology clinics, including those led by Prof. Aldo Calogero and Dr Rossella Cannarella, are expected to provide a robust phenotypic framework. Genetic testing for Mendelian forms of male infertility may help to distinguish inherited forms from cases in which environmental factors could play a more prominent role. Finally, MAGI’s multi-omics and modelling units plan to work on integrated analyses linking environmental exposure profiles, molecular pathways and reproductive outcomes, with the hope of identifying patterns that might justify more extensive investigation in larger cohorts.
The broader public-health message emerging from these discussions was articulated in cautious but consistent terms: access to clean water, uncontaminated food and a reduction in plastic-derived and industrial pollutants appears to be an increasingly important consideration for safeguarding reproductive health across generations. By placing circular biotechnology and endocrine-health research side by side, the retreat encouraged participants to reflect on how environmental factors, human biology and molecular technologies may be interconnected.
Taken together, the contributions from Prof. Iza Radecka, Dr Fidelin Tuchenbou-Magaia, Prof. Aldo Calogero, Dr Rossella Cannarella and the MAGI teams illustrated how an interdisciplinary, multi-omics perspective can help to frame both industrial processes and clinical questions within a coherent, sustainability-oriented view. Rather than presenting definitive solutions, these sessions were characterised by the formulation of working hypotheses, discussion of preliminary observations and identification of possible avenues for collaboration. In this way, they contributed to building a shared scientific language through which environmental challenges and human health may be addressed jointly in future projects.
