Cell4Chem: European research project on the production of green chemicals from residues using microbial communities
Green chemicals are still rare The Cell4Chem project is developing strategies and tools to unlock the full potential of microbial communities. Conversion processes are being researched that can be used to obtain high-quality chemicals (medium-chain carboxylates) from sustainable raw materials.
Medium-chain carboxylates (MCC) are speciality chemicals with a wide range of applications in various industries. However, they have so far been obtained from palm kernel oil or fossil raw materials. An anaerobic fermentation process is an environmentally friendly and value-adding alternative, with which MCCs can be produced from locally available organic residual and waste streams by complex bacterial mixed cultures. However, the applicability of the process is so far limited to a few substrates that are rich in ethanol or lactate.Lignocellulosic residues as a resource
Substrates containing lignocellulose are available in large quantities. The use of such substrates would greatly expand the possibilities for MCC production. However, due to their stable chemical structure, lignocellulosic substrates have so far been unsuitable as feedstock for MCC production.The key: customised microbial communities
To enable the conversion of lignocellulose into MCC, Cell4Chem relies on microbial resource management as a means of targeted process control. Engineered microbial consortia combine MCC-producing bacteria with bacterial specialists that can effectively deal with the complex nature of lignocellulosic biomass.
International and interdisciplinary
The interdisciplinary research team, consisting of cooperation partners in Germany, France, Norway, Spain and Slovenia, pursues research approaches in synthetic biology, bioinformatics, systems biology and biotechnology. The project is coordinated by Dr. Heike Sträuber and worked on at the UFZ by members of the Microbiology Anaerobic Systems (MicAS) working group at the Department of Environmental Microbiology.
Cell4Chem's broad spectrum of methods is applied in a concerted manner to ensure optimal adaptation of microbial consortia in engineered ecosystems for anaerobic fermentation, to release the full potential of microbial communities and to pave the way for their use in biotechnological processes.
Since the start of the project in 2021, numerous presentations and posters have been contributed to various events, an international opinion survey among stakeholders and the general population has been conducted, a workshop on research data management has been held and much more. Currently, a short animated film is being produced to introduce the project to a wider audience.

New biomarkers pave the way for spin-off
Within the BMBF-funded joint project "GlioPATH" (FKZ: 01ZX1402D) of the German Cancer Research Centre (DKFZ), Friedrich Schiller University Jena and the UFZ (Departments of Immunology and Ecological Chemistry), new biomarkers have been discovered for the detection and quantification of different types of cancer and for monitoring specific therapy approaches.
These transcriptional biomarkers allow to assess the activation of aryl hydrocarbon receptors (AHR), which plays an important role in many biological processes, e.g. cancer development, tumour invasion or chronic inflammatory and autoimmune diseases. In the process, the UFZ team researched the interactions of the AHR signalling pathways with the relevant metabolic pathways. This resulted in three joint inventions for which corresponding international industrial property rights were filed under the leadership of the DKFZ.
A team led by UFZ alumni Saskia Trump (formerly at Immunology Department) is now exploiting these intellectual property rights commercially and has founded cAHRmeleon Bioscience GmbH in the Heidelberg Technology Park. The spin-off develops biomarker and companion diagnostic services for precision medicine in cancer immunotherapy for the biopharmaceutical market.
Do you also have a spin-off idea? We would be happy to help you with it!

The UFZ presented solutions for agriculture and forestry at agra Leipzig
agra fair took place again. The agricultural exhibition in Central Germany enabled the agricultural and forestry sector and its service providers to present their latest developments and to exchange ideas.This spring, the
The organisers welcomed 1183 exhibitors and 50450 visitors in two halls and the large outdoor area at the Leipzig Trade Fair Centre. The main topics in 2022 were biodiversity in crop production, animal welfare and agra - forestry.
The UFZ was also there and welcomed visitors to its stand from a wide range of sectors such as agriculture and forestry, society and politics, including the Saxon State Minister for Regional Development, Thomas Schmidt. With the Drought Monitor and the Forest Condition Monitor, information services of the future were presented, as well as new product ideas for agriculture and tried-and-tested products, such as the Leipzig Foam Tester for minimising foam risks in biogas plants. The BMBF-funded BonaRes project provided information on sustainable use of the scarce resource soil.
The innovative plant tomography project received a lot of attention. This new method uses plenoptic cameras to determine plant physiological parameters without contact, thus enabling documentation of the current condition of above-ground plant parts. The in situ sensor technology is interesting for companies with field measurement technology as well as agriculture and forestry.
In addition to the specialist audience, interested members of the public were able to find out about the bee project "Leipzig hums and buzzes" and the UFZ Citizen Science projects FLOW-Monitoring (ecological monitoring of small watercourses and streams) or butterfly monitoring (recording of diurnal butterflies).
The UFZ participated in the supporting programme at the agra - Forstwelt forum with a presentation by Dr Daniel Doktor (Department Remote Sensing / RS) on the planned UFZ forest condition monitor.
All in all, UFZ researchers and the Knowledge and Technology Transfer Department were able to hold interesting discussions with the professional audience and gain insights for further research and transfer work as well as present UFZ projects.Find more Information on the UFZ presentations:

Hydrogen: Key element of the energy transition
The UFZ Department of Solar Materials is successfully researching in this field and the inventors have succeeded in receiving a European Patent (EP3592836) for their "Process for the bioreactive extraction of produced oxygen from a reaction chamber, and use of phototrophic micro-organisms in the recovery of hydrogen".
Patent applications for the process have also been filed in the USA and Canada.
It is a basic process for the production of hydrogen. By using whole-cell biocatalysis, higher yields will be possible in the long term and, in addition, the process avoids the formation of explosive oxyhydrogen gas by binding the oxygen produced directly in the cell. The UFZ has thus achieved another important success on its way to sustainable hydrogen production.
