CRISPR/Cas9 and genetic engineering laws - 27/11/2019

Transgene-free plant breeding using genome editing

Plant geneticists from Tübingen have used genome deletion to breed a variety of tomato that is resistant to powdery mildew. The CRISPR/Cas9 technology that they used enabled them to achieve this in a relatively short period of time. They also demonstrated beyond any doubt that the new tomato variety contains no foreign DNA and is indistinguishable from naturally occurring deletion mutants.

Microplastics waste is a valuable resource – it is just in the wrong place

The negative image of plastic persists and is not getting any better in the face of the ongoing debate about microplastics which are basically everywhere. Plastic pollutes the environment. The globe is littered with huge quantities. We have to modify the production and utilisation of macroplastics as well as fundamentally rethink the way we dispose of them. ‘Out of sight, out of mind’ mentality must become a thing of the past.

Plant pots made of natural fibres – "bio", no ifs or buts

Plastic plant pots are not good for the environment; strictly speaking, they should not even be disposed of in recycling bins. Alternatives such as coconut fibre pots are compostable, but not pollutant-free and not "bio" at all. The Karlsruhe-based company Fiber Engineering has developed a truly ecofriendly way to grow plants: pots made of hemp or grass, which are preserved with biological components and decompose completely within a…

Magnetised algae as microrobots for medical and environmental purposes

Algae, for most of us, is something that lives in water courses that we occasionally find unpleasant. However, that is to do them a wrong. These extremely versatile and frugal organisms might in future prove to be extremely important. Scientists at the University of Stuttgart are investigating how algae can be used as microrobots in biomedicine and environmental remediation.

Two-part interview part 2 | Prof. Dr. Ortwin Renn on the green genetic engineering debate - 26/08/2019

"Green genetic engineering is a scapegoat, but no longer an innocent one"

Many scientists are expecting revolutionary advances in research to come from new molecular biology tools such as the CRISPR/Cas gene scissors. These methods are very important for agriculture, especially plant breeding and nutrition. However, the debate on green genetic engineering 2.0 looks like it may once again be heading for ideological battles. We talked with Prof. Dr. Ortwin Renn and asked him about opportunities for better communication.

How can we achieve the internationally agreed climate targets? The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB makes the greenhouse gas CO2 usable as a carbon source for the chemical industry. With a patented catalyst synthesis, screening for the optimal catalyst in high throughput and combined (electro)chemical-biotechnological processes, various concepts are available to CO2 emitting industries.

Sustainable energy storage using egg shells

Germans consumed 235 chicken eggs per head. While egg white and egg yolks are processed into cakes, pasta or scrambled eggs, the shell predominantly ends up as organic waste. This despite the fact that eggshells are complex composites of lime and protein fibres. “It has repeatedly been shown over recent years that natural products are excellently suited for energy storage,” explains Professor Maximilian Fichtner from the Helmholtz Institute Ulm,…

Providing Growledge - resources and products for the bioeconomy

Miscanthus and hemp are biomass plants that can be used as raw materials for a wide range of products and can be grown on land areas that are currently underutilised. A European consortium led by the University of Hohenheim in Baden-Württemberg has started a five-year project to demonstrate the economic potential of these plants.

The European Union's Horizon 2020 project MAGIC has reached a milestone by uploading a beta version of its Decision Support System for farmers and end users, showing marginal land and an overview of industrial crops suitable to be grown on this land.

The alternative: “bioplastics”

Plastic waste takes years to decompose and pollutes the environment. Nevertheless, plastics are an indispensable part of everyday life. It is therefore all the more important to find a meaningful alternative that is sustainable, environmentally friendly and has better properties and more functionality than conventional plastics. In addition, such an alternative should not be dependent in any way on fossil resources.

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.
