In February 2025, the joint project "MagnI-SENSE", coordinated by Fraunhofer IME, was launched. In addition to climate change, regulatory requirements regarding chemical plant protection products (PPPs) also pose major challenges for agriculture. Plant diseases can lead to enormous harvest and yield losses, which is why PPPs are often unavoidable - but excessive use of such products leads to biodiversity loss. The amount of PPP used must therefore be optimally aligned with the actual need in the event of disease. 

MagnI-SENSE is researching four technical innovations that together offer an analysis and monitoring system for farmers to detect yield-relevant plant diseases on site. More precise predictions of the occurrence of harmful organisms will enable appropriate recommendations to be made for the reduced and targeted use of pesticides. This should enable farmers to maximize crop yields and save considerable costs in addition to the positive ecological aspect.

In February 2025, the second General Assembly of the EU-funded joint research program FEASTS (Fostering European Cellular Agriculture for Sustainable Transition Solutions) took place in Amsterdam. Prof. Stefan Schillberg (Institute Manager of Fraunhofer IME and Head of the New Agricultural Systems department in Aachen), Dr. Julius Che Ngwa (Head of the Cultured Meat working group) and Kuo-Hui Chiu (postdoc in the Cultured Meat working group) were there to exchange information with the other consortium members on research activities and novelties in the field of cultured meat. In addition to new technologies and innovations, business models were also presented, while aspects such as social relevance, sustainability, health, ethics and regulations were also discussed. 

FEASTS aims to create a comprehensive, unbiased knowledge base on cultured meat and seafood and its important role in a resilient, equitable and sustainable food system. As one of the program's collaborating partners, Fraunhofer IME is committed to promoting and advancing cultured meat research from within the New Agricultural Systems department.

The Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Federal Environment Agency (UBA) held a workshop on “New Strategies for Regulatory Bioaccumulation Assessment” from March 11-12, 2025. The aim of the event, held at the Saxony-Anhalt State Representation in Berlin, was to optimize bioaccumulation assessment processes when assessing the environmental risks of chemicals. Recognizing the central role that bioaccumulation plays in regulatory substance assessment, the workshop focused in particular on the need for modern alternatives to traditional animal testing, such as in vitro tests (e.g. OECD Test Guideline 319) or the use of non-vertebrate organisms including the freshwater amphipod Hyalella azteca (OECD Test Guideline 321). The suitability of these tests compared to the traditional fish test (OECD Test Guideline 305) and their role in test and assessment schemes was discussed by the 35 participants from authorities, industry and research from ten countries. The workshop offered a varied program with presentations and interactive discussion sessions to promote collaboration between scientific research and regulatory practice.

A joint workshop of the working groups of the Environmental Chemistry and Ecotoxicology Division of the German Chemical Society (GDCh) took place for the first time at Fraunhofer IME in Schmallenberg from 17 to 19 June 2024. Dr. Stefan Hahn from Fraunhofer ITEM, head of the GDCh division, welcomed 30 guests from science, industry and regulation. In addition to numerous technical presentations and stimulating discussions on the “Recording and evaluation of substances in the environment”, the participating colleagues from Fraunhofer IME, Dr. Dieter Hennecke, Prof. Dr. Christoph Schäfers, Dr. Bernd Göckener and Dr. Boris Meisterjahn were able to show the institute and some laboratories to their “chemistry colleagues”. The exchange between the working groups on chemicals assessment, environmental monitoring, atmospheric chemistry and soil highlighted the differences in the approaches, but also the similarities in the methods. All participants are in favour of continuing the format.

Alexandra Loll, a doctoral student at Fraunhofer IME in Schmallenberg, has been awarded the Paul Crutzen Prize in September 2024 for her publication “Short-Term Test for Toxicogenomic Analysis of Ecotoxic Modes of Action in Lemna minor”.

The prize has been awarded by the Environmental Chemistry and Ecotoxicology Division of the German Chemical Society (GDCh) since 2000 for outstanding scientific publications by young scientists in the field of environmental chemistry and ecotoxicology.

The publication, which Ms Loll wrote as part of her master's thesis, deals with the toxicogenomic investigation of the duckweed Lemna minor. To do this, she developed a shortened growth inhibition test that was combined with transcriptomics and proteomics. Compared to standardised ecotoxicological tests, this offered the advantage of a rapid evaluation of the test substances' mechanisms of action. Since the aquatic plant had hardly been genomically examined before, the bioinformatic evaluation of the complex transcriptome and proteome data was a particular challenge. The analysis allowed identification of substance-specific molecular fingerprints for both substances (atorvastatin and bentazone) and to propose biomarkers for the respective mechanisms of action. This is an important step towards effect-specific screening approaches, which could considerably facilitate the assessment of the hazards posed by chemicals to the environment.

She received the prize from Dr Stefan Hahn, Fraunhofer ITEM, at „Environment 2024“, the joint annual conference of SETAC GLB and the GDCh Division of Environmental Chemistry and Ecotoxicology, which took place this year in Gießen and Homberg (Ohm).

As part of her doctorate, Alexandra Loll is investigating the ecotoxicity of artificial sweeteners using OMICs methods.

At the beginning of December 2024, the first internal conference on specific topics of research scientists at the Fraunhofer IME location in Schmallenberg took place. Colleagues Karlheinz Weinfurtner, Dr. Sebastian Eilebrecht and Dr. Benedikt Ringbeck organised this new format, which allowed all employees of the division Applied Ecology to get an overview of the diversity of our research.

Over almost two days, the various research projects were presented in 22 talks and 10 posters: The seven sessions covered a wide range of current issues in environmental research, such as the handling of difficult test substances in environmental risk assessment, studies on the degradation of polymers and other substances, pesticide entries into the environment, modelling and OMICs methods, new ecotoxicological test methods with bacteria, algae and fish, and much more!

The lectures and posters were discussed over coffee and cold drinks, and new research projects were reviewed. The success of the conference will not only be reflected in new interdepartmental collaborations but also all participants agreed that this format should be repeated yearly.

The colleagues at Fraunhofer IME in Schmallenberg had been able to use the office space on the 3rd floor of the 6 000-square-metre new building since the previous year, but the first laboratories were occupied in 2024. The staff of the Department of Ecological Chemistry and the Department of Bioaccumulation and Animal Metabolism cleared the old radiation protection area. They transported their often highly specialised equipment for working with radioactive isotopes to their new work environment. They received active support from the maintenance workshop and radiation protection. Where the transport of highly complex measuring instruments could not be carried out with our own resources alone, equipment manufacturers also provided support. Ultimately, the relocation of the laboratories was successfully completed in due time despite very high demands from radiation protection and quality assurance.

Our colleagues have now settled in very well to their new premises and are pleased with the modern, generously sized laboratories. Some shortcomings that only become apparent during operation are being remedied step by step and will certainly keep the maintenance workshop staff on its toes for some time to come.

Anton Windfelder, young scientist in the field of radiology and alternative animal models, was honored with the Young Investigator Award 2024 of the German Radiological Society (DRG). The award ceremony took place during RÖKO Digital, the DRG's annual congress. Anton Windfelder, who works as Junior Research Group Leader for Multimodal Preclinical Imaging at Fraunhofer IME and JLU, impressed the jury with his innovative contributions to experimental medical imaging.

Anton Windfelder uses high-resolution micro-CT imaging to visualize complex anatomical structures in insects such as the tobacco hawkmoth. This research has led to the discovery of new structures in the insect's intestinal tract and provides valuable insights into the digestive system, which has comparable aspects to the human intestine. The findings thus offer relevant insights into new treatment and diagnostic approaches for chronic inflammatory bowel diseases.

Every year, the German Radiological Society (DRG) presents the Young Investigator Award to honor outstanding work and congress contributions by young scientists in order to recognize and promote the achievements of young scientists in the field of imaging.

Metamorphosis in the classroom: primary school pupils at Sandfeld School in Giessen have now been able to experience real butterflies and their larvae. During the teaching unit “From caterpillar to butterfly”, junior research group leader Dr. Anton Windfelder from the Laboratory for Experimental Radiology at Justus Liebig University Giessen (JLU) and Fraunhofer IME visited the Sandfeld School and enriched the lessons with 3D models, real tobacco hawkmoth larvae and lots of specialist knowledge about butterflies.

As part of their science lessons, second-grade classes at Sandfeldschule regularly carry out a unit on butterflies. Thanks to the breeding sets of the thistle butterfly financed by the Sandfeld School, students can explore these biological processes firsthand. "The children have a lot of fun with the caterpillars and can learn how to treat animals responsibly," says teacher Bettina Reisinger. "They learn what the animals eat and what significance they have for our environment."

When Windfelder heard about the initiative, he was immediately enthusiastic: "I think it's fantastic that the Sandfeld School is committed to environmental education and species conservation. I definitely wanted to support that." His junior research group works with butterflies and investigates how they can be better protected from environmental toxins such as pesticides.

Fraunhofer promotes a working environment in which all employees feel welcome, respected and a sense of belonging. The differences and diversity of all employees should not only be recognized, but actively encouraged.

Our BfC took this year's Diversity Day as an opportunity to organise a community lunch. All participants came together in the large conference room at 12 noon and everyone brought a dish from their home country (region). All in all, this resulted in an exciting mixture that ranged from Hessian to Portuguese and Indonesian. We exchanged ideas and realised once again that our diversity is a great enrichment.

How do dandelions end up in bicycle tires? The white sap of the dandelion contains natural rubber - a raw material from which many different rubber products can be made. However, natural rubber must first be extracted in sufficient quantities. Not all dandelions are suitable for this purpose. In the popular children's program "Die Sendung mit der Maus," host Siham El-Maimouni explored the process from seed to finished tire.

At Fraunhofer IME in Münster, she accompanied our colleagues step by step. In the greenhouse in Münster, she met dandelion researcher Dirk, who provided a fascinating insight into research on dandelions. In the lab, Silva demonstrated how she analyzes genes that are important for rubber production. Denis and Christian presented the dandelion in jars. Siham also visited our cooperation partners: at the plant breeder Eskusa, Fred demonstrated his self-developed "dandelion vacuum", which produces dandelion fluff in the middle of summer. At the Continental plant in Korbach, Germany, Siham observed the production of bicycle tires.

In November 2024, Dr. Jost Muth from the Department of Functional and Applied Genomics accepted an invitation from the Gemeinschaft zur Förderung von Pflanzeninnovation e. V. (GFPi) in Bonn. The GFPi is a non-profit organization that promotes innovation in plant breeding and research by supporting pre-competitive research activities and promoting the transfer of results. With over 60 members covering the entire agricultural and horticultural value chain, the GFPi plays a central role in the industry.

As part of their Annual Assembly, Jost Muth presented the development of molecular tools for potato breeding at the meeting of the Potato Division.
At Fraunhofer IME, we have successfully conducted research and development in the potato breeding for decades. One highlight is the amylose-free potato for the starch industry, which was achieved by inactivating the enzyme responsible for the biosynthesis of amylose. He also presented the collaborative project “High-throughput Analytics for TILLING-adapted Breeding,” in which an automated genotyping process for tetraploid potatoes was developed.

Our rubber research is currently on display twice at the museum.

Until January 11, 2026, the exhibition "Gene - Vielfalt des Lebens" provides a unique insight into the world of genes with more than 1,200 exhibits on approximately 850 square meters. The special exhibition at the LWL-Museum für Naturkunde in Münster explains interactively and comprehensively what genes are, how they influence the appearance and behavior of all living beings, and how genes can be altered by external influences. In addition to the milestones of genetics, the exhibition also discusses how genes come into contact with everyday life and epigenetic influences. At an interview station, we meet Prof. Dirk Prüfer from Fraunhofer IME, who is working with his team to genetically engineer rubber from dandelions for the production of bicycle tires. They have modified the dandelion to produce sufficient amounts of rubber in the roots. One product - the casing of a bicycle tire made from it - hangs on the wall.

Our dandelion can also be seen in the special exhibition "ZUKÜNFTE. Material and Design of Tomorrow" at the GRASSi Museum for Applied Art in Leipzig. In three chapters, the exhibition seeks answers to the question of the future role of design in society. The third chapter of the exhibition, "Material Lab", presents current research projects at the interface of biology, design, art and industry. Here, materials and products are shown that already exist and represent viable alternatives - such as the rubber from our dandelion. This locally produced raw material is now being used to make bicycle tires that are already on the market. And the tire is well received, as it is almost a work of art in itself, with many features such as small dandelions on the casing.

12th May 2024 - International Day of Plant Health

Molecular Biotechnology

The United Nations has declared May 12 as International Plant Health Day. Its aim is to raise global awareness of how protecting plant health can help end famine, reduce poverty, protect biodiversity and the environment and promote economic development. To feed the world in 2050, agricultural production must be increased by 50 percent. Protecting crops from pest infestation is of central importance. Every year, up to 40 percent of harvests worth 200 billion euros are lost due to pests and plant diseases.

At Fraunhofer IME, we contribute to advancing research and innovation in the field of plant health. Plant health is crucial for ensuring food security, protecting the environment and promoting sustainable agriculture. Our research and collaborations aim to develop innovative solutions to combat plant diseases, pests and other threats. We focus our R&D activities from self-protection mechanisms to pathogen detection and pest control.

"ReCO2NWert"

In April 2024, the industrial research project "ReCO2NWert" (implementation of the resource transition in the chemical industry through biotechnological CO2 utilization in regional value chains) started, which is funded by the BMBF as part of the structural change program. Together with nine project partners from science and industry, the Fraunhofer IME is using biotechnological processes to develop a platform technology that prevents CO2-containing exhaust gases from escaping into the environment in the first place. For this purpose, microorganisms are used as biocatalysts that utilize processed carbon-containing flue gases and, at the same time, convert them into valuable substances that can be used in industrial processes. The Industrial Biotechnology department at the Fraunhofer IME is responsible for manufacturing the production strains in the project. Modern methods of metabolic engineering and chemical analysis are used for further strain improvement.

The "ReCO2NWert" platform technology developed in the project converts the CO2-containing waste gases from the Weisweiler (Germany) waste incineration plant into synthesis gas and makes them usable for industrial applications through a gas fermentation process and subsequent purification of the resulting products. The aim is to turn the Rhenish mining area into a sustainable, bio-based industrial environment and serve as a demonstrator for the economic viability of the process. Ideally, the platform will ensure that different industry branches are connected with each other in the future, thus creating new circular economic cycles.

New OECD Test Guideline on Hyalella azteca Bioconcentration Test (HYBIT)

In June 2024, OECD published a new OECD Test Guideline on a Hyalella azteca Bioconcentration Test (HYBIT) as OECD TG 321. The test, which provides a non-vertebrate test for bioconcentration in aquatic environments, was developed over the last years under the leadership of the IME in collaboration with partners from authorities, industry and research. HYBIT has been developed in such a way that it is as close as possible to the concept described in OECD TG 305 (I) (fish flow-through test).

In addition to the established flow-through regime commonly applied in bioconcentration studies, semistatic regimes are permissible as options in studies carried out according to the new Test Guideline. Both regimes have been validated as part of a multilaboratory ring trial. The international ring trial demonstrated that the HYBIT protocol is robust and transferable among laboratories, allowing comparable performance even in labs with limited prior experience with Hyalella azteca or bioconcentration testing. The aqueous exposure test is most applicable to organic chemicals with log KOW values between 1.5 and 6.0 but may still be used with highly hydrophobic chemicals (having log KOW >6.0), if a stable and fully dissolved concentration of the test chemical in water can be demonstrated. In October 2024, the European Chemical Agency (ECHA) announced that the Member State Committee unanimously approved the non-vertebrate test HYBIT to be used as the standard information requirement under REACH where applicable.
