Dialogue instead of a chemical maze – new strategy for sustainable crop protection

Climate change creates stress. This provides an opportunity for pests to exploit plant weaknesses and reproduce. For the infested plant, this can be catastrophic and often fatal. But instead of continuing to protect harvest yields with toxic substances as before, the transnational DialogProTec project is now taking a completely new approach: researchers want to intervene in the communication between plants and pests to keep them healthy.

Microalgae - high-quality products for domestic agriculture?

Algae are aquatic organisms that flourish in a huge variety of species. But that's not all: they are also small green mini-factories that can produce all kinds of valuable materials. All they need is water, light, CO2 and a few nutrients that can be recycled from biogas or sewage treatment plants. Researchers have now determined the optimal framework conditions and practicability of process methods for agricultural algae cultivation.

Tübingen biotechnologist Lars Angenent is being awarded the Leibniz Prize by the German Research Foundation (DFG) in appreciation of his outstanding work in the field of environmental biotechnology, it was announced in Bonn on Thursday. The DFG said: “In view of climate change and the resulting need to develop a sustainable food, chemistry and energy economy, his work is highly relevant.”

More animal welfare and better animal health, more climate protection and less environmental impact: Researchers at the University of Hohenheim in Stuttgart are pursuing these goals with a new approach: They are exploring the interplay between farm animals and the millions of microorganisms in the animals’ digestive tracts. The federal and state governments are supporting the university with the construction of a unique research center for around…

Mini-factories for producing bioplastics - 05/05/2022

Bacteria produce bioplastics: resource-saving and very environmentally friendly

Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.

Acid whey as a valuable raw material for platform chemicals and more

There is not much you can do with acid whey, which is why several million litres of it are disposed of every year. This is both costly and not sustainable. However, researchers at Tübingen University have shown: acid whey can be used to produce precursors for biofuels, fine chemicals and antimicrobial livestock feed additives. They have set up the pre-start-up company Wheyfinery in an endeavour to make their scalable biorefinery concept…

Making important raw materials for fine chemicals out of carbon dioxide really works. As part of the Max Planck collaborative project eBioCO2n, a team of researchers from Fraunhofer IGB have successfully performed a first ever fixation of CO2 via a multi-enzyme enzyme reaction driven by electricity yielding a prospective intermediate for the chemical industry. The process for electro-biocatalytic CO2 fixation was recently published and is…

Microbiologists at the University of Tübingen modify bacteria to produce climate-neutral and rapidly degradable bioplastics.

For quite some time now, the European Commission (EC) is putting a special focus on biodegradable and compostable polymers when assessing the general role of bioplastics.

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

Germany generates around 38 kilograms of plastic waste per capita each year. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer Institute for Process Engineering and Packaging IVV are now working to establish a holistic concept for the sustainable use of biologically degradable packaging materials in the cosmetics industry. The project is focusing on polyhydroxyalkanoates (PHAs).

Bioplastics make wood cycles more sustainable

Innovative technologies and bacteria can transform wood residues into sustainable bioplastic packaging. Before bioplastics are broken down into CO2 and water in an environmentally friendly way, they can thus lead lives as products in the cosmetics industry, for example.

Electronic devices are still made of lifeless materials. One day, however, “microbial cyborgs” might be used in fuel cells, biosensors, or bioreactors. Scientists of Karlsruhe Institute of Technology (KIT) have created the necessary prerequisite by developing a programmable, biohybrid system consisting of a nanocomposite and the Shewanella oneidensis bacterium that produces electrons.

For hundreds of millions of years plants have had the ability to harness carbon dioxide from the air using solar energy. The Max Planck research network MaxSynBio is on the trail of building artificial cells as sustainable green bioreactors. The research team led by Tobias Erb from the Institute for Terrestrial Microbiology in Marburg has now succeeded in developing a platform for the automated construction of cell-sized photosynthesis modules.

Simple sugar could soon compete with glyphosate

For many decades, glyphosate has been a common component of agricultural pesticides worldwide, although it is a controversial herbicide that may be harmful. The good news is that a more sustainable alternative is now in sight: researchers from the University of Tübingen have discovered a sugar molecule called 7-deoxy-sedoheptulose (7dSh) which inhibits the growth of plants and microorganisms, but appears to be completely harmless to human cells.

Chemists and microbiologists at Tübingen University discover sugar molecule that inhibits the growth of plants and microorganisms and is harmless to human cells ‒ An alternative to controversial glyphosate?
