Revealed: The Surprising Role of Fungus in Lab Innovations — Discover How It’s Creating Incredible Structures!

Researchers have crafted an innovative living material that draws inspiration from natural structures like bone and coral. This project, led by Chelsea Heveran from Montana State University, combines fungus and bacteria to create a substance that might enable buildings to grow, repair themselves, and lower greenhouse gas emissions tied to construction.

The foundation of this new material is made from mycelium, the root-like structure of fungi. The team used the species Neurospora crassa as the base. To enhance its strength, they introduced the bacterium Sporosarcina pasteurii, which reacts with urea in the environment to produce calcium carbonate—a substance also found in eggshells and seashells.

Heveran and her team took cues from how bones develop in nature. They noted that bones are strong yet lightweight, thanks to a process called biomineralization that occurs on a framework of collagen. By merging mycelial scaffolding with bacterial mineralization, they aimed to imitate this balance.

What stands out is that previous attempts at creating living materials typically lasted just a few days. In contrast, this fungal-bacterial combination remained viable and stable for at least a month. Heveran expressed excitement about the possibilities this presents. With further engineering, they hope to imbue these materials with traits like self-healing, environmental sensing, and detoxification.

The environmental implications of this research are profound. Concrete production is responsible for over 5% of global human-made greenhouse gas emissions. By introducing biologically active materials, we could significantly shrink the carbon footprint of construction. Aysu Kuru from the University of Sydney, who wasn’t involved in the research, pointed out that using mycelium as a base material is a simple yet powerful idea.

The concept also hints at a future where buildings aren’t merely static structures but living systems capable of growth, self-repair, and environmental responsiveness. While more research is necessary to enhance the longevity and scalability of these materials, the potential to reshape our approach to construction is exciting.

This blend of biology and architecture could mean we’re moving toward a future where we cultivate our buildings instead of just building them. As we refine these fungus-based materials, we might just uncover the next generation of sustainable construction solutions.
