More and more consumers are turning to plant-based meat substitutes. Even though these products look very similar to their animal counterparts, the difference is noticeable when consumed. In terms of texture and taste, they often cannot yet compete with the original. Symrise AG, based in Holzminden, Germany, will work with researchers at Wageningen University in the Netherlands to improve the sensory quality of meat substitute products.

Microorganisms such as bacteria, fungi and yeasts are the invisible little helpers of the bioeconomy. Thanks to them, biological resources can be tapped, new bio-based products manufactured and production processes made more sustainable. To draw attention to the diversity of microbes and their great potential for application, the members of the Association for General and Applied Microbiology (VAAM) vote for the Microbe of the Year. This year, Bacillus subtilis is in the spotlight.

Biodegradable plastics do not disappear from the environment as quickly and easily as their name promises. Instead, many plastics degrade only very slowly or partially. Researchers at the University of Bayreuth have developed a new approach that could alleviate this problem: They incorporate enzymes into the plastic during production that later effectively degrade the material in wastewater treatment plants or composting facilities.

Plants have several protective strategies against insect pests: They can mechanically make it difficult for them to pierce or eat the leaves. They can make their taste or nutritional value unattractive. Or they can go one step further and produce substances that harm predators. But sometimes, in the course of evolution, insects fight back and bypass these defense methods. The cabbage white butterfly is a case in point.

From vanilla crescents to pepper nuts: Cookies and pastries are very popular at Christmas time. Many of these treats contain imported spices that only grow in faraway countries like India. As an alternative, vanilla and pepper could soon also thrive in domestic indoor farms. Osnabrück University of Applied Sciences has now paved the way for this. After two years of construction, the "Indoorfarm - Agricultural Systems of the Future" research center was officially opened at the Haste campus at the end of November.

Coat hooks are usually made from conventional plastics. Every year, up to ten billion of them are produced worldwide to display textiles such as socks, caps or scarves in fashion stores. However, only a small proportion of these are recycled. Disposable hooks in particular pose a recycling challenge due to their size. Yet this could soon change: With a textile hook made from plant-based biopolymers, traceless materials is now starting field trials for the first pilot product.

Euglenoids are found primarily in shallow and sweet waters such as ponds and village ponds, but also in the sea, brackish water or even salt lakes. The exceptionally wide distribution of these single-celled organisms makes them survival artists that have long fascinated researchers worldwide. However, of the 1,000 known species, only 20 have been studied.

Electromobility is experiencing rapid growth. However, important issues relating to the charging infrastructure for electric cars remain unresolved. Further, there will continue to be areas of application in the mobility sector for which battery-electric solutions are less suitable. Synthetic, CO2-neutral fuels could cover these areas. A team of researchers at Coburg University of Applied Sciences is now investigating another approach to producing biogenic, climate-friendly diesel.
