Chapter 1: A true story of science, mushrooms and pure gold

It was 2019 when a group of Australian scientists from the prestigious CSIRO (Commonwealth Scientific and Industrial Research Organization) were investigating new, sustainable ways to explore and extract valuable minerals from the soil. While studying microbes in the Australian subsoil, they came across a fungus already known for its destructive role in agriculture: Fusarium oxysporum.

This fungus, which often causes wilting in crops like tomatoes and bananas, didn't seem to be anything out of the ordinary. But in a soil sample taken from a former mining area, something caught the researchers' attention: microscopic crystals of pure gold coating the fungal filaments.

At first, they thought it was contamination. How could a living organism, a simple fungal life form, be covered in one of the most precious metals on Earth?

1.1 Then a thorough investigation began.

Under electron microscopy, they observed that the gold was not external dust. It had been produced by the fungus, adhering in a controlled manner to its structure. Chemical tests revealed that it was metallic gold (Au⁰), in its purest form.

The team, led by microbiologist Dr. Tsing Bohu, discovered that this strain of Fusarium Oxysporum had the ability to absorb gold ions (specifically Au³⁺), dissolved in groundwater or trapped in rock particles. Through a biological mechanism not yet fully understood, the fungus chemically reduced these ions and transformed them into metallic gold.

A kind of natural alchemy.

Once reduced, the gold was deposited as tiny nanoparticles on the surface of the mycelium (the body of the fungus). This not only protected the fungus from potential metal toxins but could also be part of its metabolism, enabling it to survive in extreme soils.

"It was as if the fungus were using gold as armor," Bohu said. "It doesn't do it to get rich, of course, but to adapt to its hostile environment. It's an extraordinary evolutionary strategy."

1.2 From disease to screening tool

The discovery wasn't just a curiosity. It opened a new frontier in science: biomining. If a fungus could locate and accumulate gold, perhaps these organisms could be used to:

• Detect hidden gold deposits.

• Extract gold from poor soils without cyanide contamination.

• Recover gold from industrial or electronic waste.

The fungus acts as a natural bioindicator. If it appears in certain areas, it could mean that traces of gold are present, although invisible to traditional methods.

1.3 What if this mushroom lived in your flower pot?

The most fascinating part of the discovery is that Fusarium Oxysporum is not a rare or exclusive organism. In fact, it can be found in common garden soils and flowerpots, although not all strains have the ability to "grow gold."

The idea that a simple flowerpot, on a balcony or in a garden, can house an organism capable of generating pure gold from invisible particles breaks with the classic image of mining and forces us to think of new ways of interacting with the Earth. 

1.4 Is this modern alchemy?

Ancient alchemy sought to transform lead into gold. This fungus does not convert materials into gold as such, but it does perform a real biological transmutation: it converts invisible gold dissolved in water into solid, visible gold through enzymatic and reduction processes.

Instead of furnaces and secret formulas, it does so with microscopic life, in the damp darkness of the ground. It is a living, silent, and completely natural alchemy.
