Enzymes are now indispensable for many industrial sectors. Their potential to naturally refine products or accelerate production processes as catalysts makes protein molecules secret stars of biotechnological processes. Detergent manufacturers in particular can no longer do without these multi-talents. More and more textiles today consist of a mixture of fibers - such as cotton and polyester.  In addition, there are new materials for outdoor textiles made mainly from synthetic fibers. This also poses new challenges for detergents.

Along with soya and corn, sugar cane is one of the most important crops in Brazil. It is used to produce not only sugar but also biofuels such as ethanol. However, processing produces enormous amounts of bagasse - fibrous remains - which up to now were not used efficiently. Instead, the lignocellulosic residual material is burnt in inefficient incinerators and usually disposed of in landfills or scattered on fields. But ash is more than just burned biomass. It contains nutrients such as phosphorus, which are essential for plant growth.

When you think of fuel cells, you don't necessarily picture bacteria. However, microorganisms also need energy for their metabolism and obtain it through electrochemical processes. Excess electrons are released into the environment by the unicellular organisms. Biotechnologists want to take advantage of this fact to drive microbial fuel cells. The project "Textile Carbon Electrodes for Microbial Fuel Cells" (TexKoMBZ) has developed a special anode that makes future industrial-scale applications seem realistic.

Many people suffer from food allergies. According to estimates by the German Allergy and Asthma Association (DAAB), around six million children and adults are affected in Germany alone. Peanut allergy is particularly widespread. So far, allergy sufferers have had to do without allergy-causing foods such as peanuts or mustard, as the condition cannot yet be cured.

Pre-processed food needs to become healthier, this is the mission of practically all producers. Sugar promotes obesity, salt cardiovascular diseases. When it comes to reducing the amount of these ingredients in a product, however, manufacturers' primary method has been to lower the recommended portion size. Tests with alternative, healthier formulations have shown that products that contain less sugar or salt than consumers are used to rarely meet their taste expectations - and fail to capture the market.

They sit tight on the seabed, and even the waves hitting the coast can’t harm them – mussels. The secret of their resilience lies in their feet: The shellfish’s feet produce a protein that sticks underwater like no other substance. Be it stone, metal, or plastic: the mussel adhesive sticks extremely well to almost any surface.

Germany has a recycling problem, even if it appears to be different at first glance. While the Federal Environment Agency reported a recycling rate of 99.4% for 2017, slightly more than half of the 6.15 million tonnes of collected plastic waste was thermally recycled, i.e. used to generate heat in waste incineration plants, cement works or power stations. Material recycling amounted to only 2.87 million tonnes (46.7%). This process conserves around three times as much of the energy contained in the plastic as can be used thermally by burning it.

"No action without reaction" is a phrase that implies that every action has consequences. The shift from a petroleum-based economy to a sustainable, bio-based one entails multi-faceted changes - on a global scale. Sociologist Maria Backhouse is convinced that "no social changes, including technological developments, take place in a vacuum", but are "permeated by social inequalities from the global to the local level".

Herring, pike-perch or salmon: fish is among the top healthy foods. The demand has been high for years. According to the Federal Statistical Office, in 2018 each person in Germany consumed about 13.7 kilograms. But Myron Peck knows that climate change will dictate which fish ends up on the plate in the future.
