Vegan cheese alternatives have one thing in common: they contain neither casein nor whey protein - although these proteins are crucial for the characteristic flavour and texture of cheese made from animal milk. Formo has found a way to produce these essential milk proteins - especially caseins - with the help of microorganisms. The Berlin-based food tech start-up uses precision fermentation to produce animal-free cheese products.

The wood-processing industry produces large quantities of wood waste, which until now has either been disposed of at great expense or utilised for energy. Waste wood treated with wood preservatives can currently only be incinerated in special large-scale power plants, as the exhaust air has to be cleaned of the harmful substances. In the ‘H2Wood – BlackForest’ project, Fraunhofer researchers and their partners have now specifically sought alternative uses for wood waste in the Black Forest region, which is heavily characterised by wood processing.

The soil fungus Mortierella alpina is no stranger to biotechnology: It is already being used to produce long-chain fatty acids, which are used as food supplements for baby food, for example. Researchers from Jena now report that the soil fungus could also be the key to sustainable agriculture.

Traditionally, the Federal Ministry of Food and Agriculture (BMEL) organises the World Food Conference in Berlin at the start of the Green Week to kick off the year. This year, around 2,000 representatives from politics, business, science and civil society will once again discuss global agricultural and food policy issues in the CityCube from 15 to 18 January. The 17th edition of the Global Forum for Food and Agriculture (GFFA) will focus on the topic of ‘Shaping a sustainable bioeconomy’.

Fish is one of the most popular foods in Germany. In order to meet the high demand and avoid overfishing, fish such as salmon and trout are often bred in aquacultures. However, enormous quantities of wild stocks are processed into fishmeal and fish oil and added to the feed. In this way, the farmed fish are supplied with vital and polyunsaturated omega-3 fatty acids such as docosahexaenoic acid (DHA), which are essential for a healthy diet.

Wood is a versatile and sought-after raw material in Germany and has to be imported in large quantities due to the high demand. An alternative to wood could be plants from paludiculture, as peatland plants also contain important wood components such as cellulose and lignin. Reeds and peat mosses are already being used for building materials, animal feed and food. Now the paper industry could also benefit from peatland plants as a wood substitute. Researchers at the Fraunhofer Institute for Process Engineering and Packaging IVV have now provided proof of this.

How can nutrients such as phosphorus and nitrogen, which are removed from the environment through the cultivation and consumption of food, be returned? This question was the focus of the ‘zirkulierBAR’ project, which was supported by the Federal Ministry of Education and Research (BMBF) from 2021 to 2024 as part of the REGION.innovativ funding programme. Following the completion of the three-year project, which was coordinated by the Leibniz Institute of Vegetable and Ornamental Crops (IGZ), the consortium has now summarised its results and findings in a handbook.

Humus is known to be good for the soil. The complex mixture of organic matter, such as dead animal and plant remains, serves as a food source for plants and soil microbes alike and is therefore a driving force for plant growth and soil health. It is primarily the humic substances contained in humus that ensure that moisture and nutrients are bound in the soil, convert microbial biomass into nutrient-rich biostimulants and make these available to plants. In practice, however, things often look different.

Potting soils usually contain peat, which is formed from dead plant remains in bogs. However, peat extraction destroys the habitats of many plants and animals as well as a valuable carbon store. There are now alternative plant substrates such as coconut pulp and fibres. However, the raw materials have to be imported from India or Sri Lanka. In the TOPKO project, researchers at Oldenburg University of Applied Sciences and industrial partners now want to prove that regional raw materials are also suitable as a peat substitute for plant substrates.
