Alongside fats and carbohydrates, proteins are the main nutrients that the human body needs. Proteins serve as a building material for cells and tissue, can repair bones and tissue or control metabolic processes in the body as an enzyme. Researchers have therefore been endeavouring for years to recreate proteins on the computer and give them better properties. An international research team led by the Technical University of Munich (TUM) has now developed a new method for designing proteins. 

Climate change and dwindling resources are already posing major challenges for industry today. The industrial bioeconomy offers solutions for replacing fossil fuels with renewable raw materials, closing cycles and thus contributing to a resource-efficient and climate-neutral industry.

Electrochaea GmbH is using a promising technology to make the production and, above all, storage of sustainably produced gas even more efficient. It involves microorganisms that are billions of years old, known as archaea, which act as biocatalysts in the conversion of electricity into gas. Following demonstration plants in Denmark, Switzerland and the USA, a biomethanisation plant will now also be built in Japan. According to Electrochaea, a corresponding five-year licence agreement has been concluded with the Japanese energy company Hitachi.

So-called antigen tests have been common knowledge since the coronavirus pandemic at the latest. They have long been used in medical diagnostics to detect certain viruses in saliva, blood or urine. However, the antibodies required for this are largely derived from animal cells or living animals. Now the Hanover-based start-up Phaeosynt wants to produce antibodies from algae. The German Federal Environmental Foundation (DBU) is funding the project with 125,000 euros.

In Europe, 7.5 million tonnes of used clothing end up in the bin every year. This is according to a study by management consultants McKinsey & Company. According to the study, a maximum of 30-35% of textile waste is recycled.

Residual materials from agriculture, forestry, the paper industry and food production have long since become a valuable source of raw materials for new bio-based and sustainable products.

In 2022, Federal Research Minister Bettina Stark-Watzinger signed an agreement to strengthen joint bioeconomy research during her visit to the Australian state of Queensland. With the ‘Joint Declaration of Intent’, Germany and Australia want to expand their long-standing research cooperation.

Wheat is one of the most important food crops in the world and is dependent on a supply of nitrogen. In agriculture, nitrogen is therefore applied in the form of fertiliser to promote plant growth and achieve good yields. However, the right amount is important. Nitrogen that the plant cannot process ends up in the environment and pollutes ecosystems. But how can the supply of wheat be secured without further harming the environment?

Microorganisms such as bacteria, fungi and viruses never act alone. They form communities, interact and thus have a significant influence on humans and nature. One example of this is the microbial community in the human gut, the so-called microbiome. It is only through the interaction of microorganisms that nutrients are metabolised and made usable for the body. However, if the microbiome is composed incorrectly, this can lead to health problems.
