Bioeconomy

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…

Researchers find the enzymatic link in the formation of methane from fatty acids by cooperating microorganisms. Microbial production of methane from organic material is an essential process in the global carbon cycle and an important source of renewable energy. This natural process is based on a cooperative interaction between different types of microorganisms: the fermenting bacteria and the methane-producing archaea.

Carbon dioxide is one of the main drivers of climate change – which means that we need to reduce CO2 emissions in the future. Fraunhofer researchers are highlighting a possible way to lower these emissions: They use the greenhouse gas as a raw material, for instance to produce plastics. To do this, they first produce methanol and formic acid from CO2, which they convert via microorganisms into building blocks for polymers and the like.

Nut snack as a sustainable ecological concept

A delicious vegan nut snack that uses no sugar, artificial additives, gluten or palm oil, is full of essential nutrients, and is part of a commitment to environmental and social sustainability. Impossible? An Esslingen-based start-up called kernique proves otherwise. The start-up is currently planning a crowdfunding phase that offers a lucrative deal for investors. The idea catches the zeitgeist, but what exactly makes it stand out?

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

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.

Packaging of the future

What will the packaging of the future look like, and what will be required of it? Can packaging be biobased, recyclable, sustainable and economic? In Baden-Württemberg, there are various approaches to developing packaging with the above properties from various sources including agricultural residual and side streams as well as municipal waste.

Time for climate protection is pressing. One approach to tackle this challenge is to use the greenhouse gas CO2 as a raw material for chemicals. The researchers of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, together with partners from science and industry, were able to produce a value-added terpenoid dye from CO2 adsorbed from air by a combination of electrochemical and biotechnological conversion.

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.

Sensors for the bioeconomy

Sensor networks are one of the keys to achieving digitalisation of the bioeconomy. Sensor networks are on the way to becoming important analysis and control instruments for energy-efficient and sustainable material cycles. Dieter Hertweck, Professor of Business Information Systems at Reutlingen University of Applied Sciences, shows what is already possible in digital agriculture and waste recycling and what is feasible for the future.

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?

The state of Baden-Württemberg is characterised by strong economic expertise in the field of plant and mechanical engineering as well as excellent research institutions in the fields of biology, biotechnology, bioprocess engineering and chemistry. These form an excellent basis for a sustainable economy by promoting technology development and innovation for tomorrow’s bioeconomy.

Flexible biogas plant operation – new concepts for stabilising bioenergy provision

The lack of flexibility with regard to peak demand for electricity – both for consumers and producers – is a well-known problem as far as the production of electricity from renewable resources is concerned. Biogas plants present a particular challenge due to the complex and relatively slow microbial processes involved. A research project called FLEXIZUCKER at the Universities of Ulm and Göttingen aims to make biogas production more flexible and…

Cyanobacteria: real all-rounders – biofuel producers and climate savers

Prof. Dr. Annegret Wilde and Prof. Dr. Wolfgang Hess from the Institute of Biology III at the University of Freiburg have been using the versatile cyanobacteria for quite some time. The two researchers are part of the project "Cyanosys - Systems biology of cyanobacterial biofuel production", which aims to use cyanobacteria for the large-scale production of biofuels from sunlight and carbon dioxide.

Industrial biotechnology: a challenging change to the raw material base

Biogenic raw materials have never been as popular as they are now. Efforts to tap renewable carbon resources are already underway, despite the fact that new oil drilling technologies are boosting fossil fuel stockpiles. In the medium term, industry will have to expand its raw materials base, and in the long term it may have to renew it completely. Industrial biotechnology is one of the key technologies in the transition from an economy based on…
