Fungi: the Unsung Heroes of Sustainability

Fungi don't just grow on old loaves of bread; they also hold potential for large-scale sustainable applications such as construction materials, mushroom leather, and meat substitutes. Professor Arthur Ram from Leiden University, specializing in Fungal Genetics and Biotechnology, illustrates how these organisms can contribute to sustainability.

In construction materials and the packaging industry, the use of fungi is on the rise. Companies are experimenting with fungi as an alternative to traditional materials like styrofoam and packaging materials. Fungi can create a sturdy structure by forming fungal threads when grown on a substrate such as straw. This mycelium can then be pressed into molds, creating various shapes.

Fungi Producing Cheese Protein

Ram and his team are not only exploring applications in the materials industry but also focusing on biotechnological aspects. They aim to have fungi produce proteins, such as casein, the main protein in cheese. Through genetic manipulation, fungi can be prompted to produce these proteins, potentially offering a sustainable alternative to animal proteins.

Breaking Down Plastics

Another fascinating aspect of their research is focused on breaking down lignin, a substance that is typically difficult to degrade and mainly used in combustion processes. Ram and his team are attempting to have fungi produce enzymes that can effectively break down lignin, which could lead to the production of valuable building blocks for bioplastics.

The application of fungi has the potential to contribute to achieving sustainability goals, according to Ram. He emphasizes that fungi can play a role in addressing various challenges in sustainability and may even contribute to all seventeen Sustainable Development Goals of the United Nations.
