Recent research shows effectiveness of biosurfactants - 28/11/2023

Combating oil spills - biosurfactants can stimulate microbial oil degradation

Oil spills from drilling platforms and tankers cause environmental pollution and a loss of biodiversity. Researchers at the University of Stuttgart, among others, are now using biosurfactants to improve the management of oil spills: their latest research shows that biosurfactants lead to better microbiological degradation of oil components in seawater compared to conventional dispersants.

Eco-friendly artificial turf: a sports pitch that’s good for people and the environment

There are thousands of artificial turf pitches in Germany. They are extremely practical, but often not at all environmentally friendly. When it rains or the pitch is used, plastic particles from the rubber granules can be released into the envronment, where they remain. Researchers at the University of Stuttgart along with the company TECNARO are now developing an artificial turf with an infill that biodegrades as soon as it leaves the pitch.

Konstanz chemists develop mineral plastics with numerous positive properties from sustainable basic building blocks and, together with biologists, demonstrate the material's excellent microbiological degradability.

Can biosurfactants increase microbiological oil degradation in North Sea seawater? An international research team from the universities of Stuttgart und Tübingen, together with the China West Normal University and the University of Georgia, have been exploring this question and the results have revealed the potential for a more effective and environmentally friendly oil spill response.

PeePower™ – energy from urine

The objective of the PeePower™ BUGA 2023 collaborative research project is to produce green hydrogen and platform chemicals from wastewater. This fits in nicely with BUGA 2023’s (German National Garden Show) four major themes, namely, climate, energy, environment and food security.

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.

ValBio-Urban brings bioeconomy research to users

Reducing carbon dioxide emissions and the capture and utilization of CO2 are important steps towards achieving a climate-neutral and sustainable economy. Accordingly, as part of the ValBio-Urban research project, an interdisciplinary team from the University of Stuttgart is developing bioeconomic approaches to solutions that will be implemented with companies from Baden-Württemberg.

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.

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.

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.

Scientists to combat antibiotic-resistant bacteria in wastewater

In Germany, around 1,500 tonnes of antibiotics per year are administered to humans and animals. As a result, more and more bacteria are developing resistance to common antibiotics. As part of HyReKA, a cooperative project funded by the BMBF, scientists led by Professor Thomas Schwartz from the KIT are investigating how antibiotic-resistant pathogens spread and how they can be prevented from doing so.
