Natural substance with herbicide potential - 10/12/2020

The same but different: What makes sugar 7Sdh a better herbicide?

The sugar 7-deoxy-sedoheptulose (7dSh) is produced by cyanobacteria and inhibits the same metabolic pathway as the broad-spectrum herbicide glyphosate, thus making it an excellent herbicide candidate. Despite this amazing similarity, the microbiologist who discovered 7dSh, Prof. Dr. Karl Forchhammer, believes that this sugar has clear ecological advantages over glyphosate.

Products made from bio-based plastics must undergo the same testing procedures as conventional plastic products to access the market of the European Union (EU). Thereby a health risk for consumers is excluded. Plastics intended to be certified as biodegradable or compostable must undergo additional tests.

Learning from honey bees

Biosensors are used in medical diagnostics and food and environmental analyses, to name just a few examples. apic.ai, a start-up based in Karlsruhe, uses honey bees as bioindicators to gain insights into the state of the ecosystem. The company also uses artificial intelligence (AI) methods for their ecotoxicological investigations.

Microplastic in waters – mini waste as maxi problem

New studies reveal that rivers are major contributors to marine ecosystem pollution. A study commissioned by environmental authorities in BW and four other German states analysed samples from 25 rivers to gain an idea of the occurrence of microplastics in German inland waters. In addition, Dr. Natalie Orlowski from the University of Freiburg is analysing microplastics pollution in the Dreisam River.

Textiles: water-repellent thanks to fungal proteins

Outdoor lovers and athletes love them: water-repellent jackets and trousers. However, many consumers are unaware that the chemicals used to functionalise the textile surface often pollute the environment. Organic fluorine compounds (perfluorocarbons = PFC) are usually added to textiles to make them water-repellent. Scientists at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Hohenstein Group are researching an…

Nanofur for cleaning up accidental oil spills in water

Accidental oil spills such as those following oil disasters need to be cleaned up as quickly as possible. Researchers from the KIT in Karlsruhe have now developed an environmentally friendly process that can eliminate oil spills effectively. Nanofur is a material that imitates the fine hairs of aquatic ferns and is capable of absorbing large amounts of oil within a relatively short time.

The aluminium trees of Sulawesi

Trees of the genus Symplocos in the Indonesian mountain rainforest store so much aluminium in their leaves that it can be used for dyeing textiles. A research project at the University of Ulm aims to preserve the traditional dyeing methods of Indonesian weavers, protect these rare trees and increase our knowledge of aluminium-accumulating plants.

Pesticides and their effect on the environment

Ecotoxicologists from Tübingen are calling for new interdisciplinary approaches in order to improve investigations into the effect of pesticides on the living environment. They expect that a more effective and more frequent combination of field work and laboratory analyses will provide them with a clearer picture of the overall situation. This knowledge will enable all stakeholders involved in solving environmental issues to draw the right…

Determination of the risk potential of particulate matter from wood combustion

Polycyclic aromatic hydrocarbons found in particulate matter in our environment are currently being studied by a network of institutes and research institutions, both in Germany and around the world. The impact of polycyclic aromatic hydrocarbons and other toxic components of particulate matter on human and animal health is not yet known in detail. However, their impact on the development of lung diseases such as asthma and other chronic…

Worn down and financially exhausted, but more popular than ever

When academic toxicologists in a German state join forces, it is virtually headline news. This is because the discipline is on the red list. Only in Baden-Württemberg does the number of toxicologists at university institutes justify the joining of forces. The ironic thing about this is that the competence of the rare species ”toxicologicus” is in greater demand than ever.
