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?

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.

From biomass to diesel

Using the power of microbes: biochemists from Leipzig and Tübingen use the combined power of microbes and electrolysis to produce fuels from organic material. This new process uses electricity from renewable resources to produce diesel from organic waste and green cuttings, amongst other things, and can therefore also be used for storing wind and solar energy.

A metal enzyme that can cleave benzene rings

Aromatic rings are extremely stable and very difficult to break apart. Prof. Dr. Matthias Boll from the University of Freiburg’s Faculty of Biology and his team work with Geobacter metallireducens, a bacterium that can completely degrade aromatic compounds under strictly anaerobic conditions. While the biological degradation of aromatic hydrocarbons is of global relevance, the chemical resulting from the reduction of benzene rings could also be…

Scale is key: biodata for optimising bioproduction

Biotech research is aimed at improving industrial-scale microbial production, making it more profitable and more competitive. However, laboratory-scale data cannot easily be transferred one to one to large-scale production. New systems biology concepts for the simulation of large-scale production are now set to make this possible.

An ingenious trick of nature: bacterial toxin-antitoxin systems

Cyanobacteria, also known as blue-green algae, are the oldest known form of life and have been around for 3 billion years. It stands to reason therefore that they should be relatively simple and primitive organisms. But this is not quite the case: two scientists from the Institute of Biology III at Freiburg University, Stefan Kopfmann and Prof. Dr. Wolfgang Hess, have discovered that cyanobacteria have developed a clever natural selection…

Soil bacteria to produce new antibiotics

An ever-growing number of genomes of soil bacteria of the genus Streptomyces are being sequenced. Using a method known as “genome mining”, researchers at the University of Tübingen are working on the identification of gene clusters that have the potential to be used in industrial biotechnology for the production of new antibiotics and other pharmaceutically active substances. To achieve this, the biosynthesis gene clusters are integrated into…

DFG research group to unravel prokaryotic immune system

It is difficult to believe that unicellular organisms such as archaea and bacteria can have developed sophisticated strategies to fight off foreign nucleic acids. However, many of these tiny organisms actually possess a virus defence mechanism known as CRISPR/Cas. Compared to this defence mechanism, protective mechanisms such as restriction and modification appear extremely clumsy indeed.
