Mushrooms break down organic matter and absorb energy through mycelium
Mushrooms are the fruiting bodies of fungi. They get their energy by decomposing dead or decaying organic material, such as fallen leaves, dung, wood, and even plastic and nuclear waste. This process of breaking down organic matter is critical in maintaining healthy soil, recycling leaf litter, and providing food for the bacteria and animals that live in the soil.
The mycelium is the root system or vegetative body of a mushroom. It is a dense network of thin filaments called hyphae, each surrounded by a robust fungal cell wall. The mycelial network intertwines with the substrate the fungus is growing on, such as wood, soil, compost, or grains, forming an inseparable mass. The purpose of the mycelium is to find and break down food sources in the substrate and collect nutrients and water for the creation of the mushroom.
The hyphae secrete enzymes onto their food source, which break down biological polymers into smaller units. These smaller units are then absorbed into the mycelium by facilitated diffusion and active transport. The enzymes break down the surrounding dead organic matter, and the hyphae facilitate the movement of the nutrients to the mushroom.
Through their mycelium, fungi can also partner with the roots of plants, creating a cross-kingdom web known as a mycorrhizal network. This allows the fungi to help plants absorb water and nutrients from the soil, while the plants provide sugars and fats to the fungi.

Mushrooms can be combined with bacteria to generate electricity
Mushrooms, or fungi, obtain their energy by decomposing dead or decaying organic material, such as fallen leaves or dung. They break down organic things and absorb energy through mycelium.
In recent years, researchers have discovered a way to combine mushrooms with bacteria to generate electricity. This combination of mushrooms and bacteria is called a "bio-hybrid" or "bionic mushroom".
The process involves using 3D printing to deposit bacterial cells onto the surface of a mushroom. The bacteria used in this process are photosynthetic and are capable of producing electricity. When light is shone on the mushroom, the bacteria begin to photosynthesise and produce electrons, which flow into a network of graphene nanoribbons, creating an electric current.
The amount of electricity produced depends on the density and alignment of the bacteria, with more densely packed bacteria producing more electricity. While the amount of electricity generated by these bionic mushrooms is currently small, researchers believe that this technology has the potential to be used in various fields, including defence, healthcare, and the environment.

Mushrooms can be used to create biodegradable batteries
Mushrooms, the fruiting bodies of fungi, obtain power by decomposing dead or decaying organic material. They break down organic matter and absorb energy through mycelium.
Now, scientists have discovered that mushrooms can also be used to create power. Researchers at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have created a biodegradable battery using mushrooms. The battery is 3D-printed with fungal cells mixed into the printing ink. The fungal cells can use cellulose as a nutrient and help break down the battery after use. This unique feature makes the battery entirely recyclable and compostable.
The process of creating this battery involves structuring the electrodes in a specific way to provide microorganisms with easy access to nutrients. The fungal battery is encased in beeswax and can be stored in a dried state. It can be activated on location by simply adding water and nutrients. The simple sugars act as good nutrient sources, feeding the fungi as part of the electricity-generating process.
While these fungal batteries do not produce a lot of electricity, they can power small sensors or temperature monitors for a few days. This makes them suitable for use in agriculture or research in remote regions. The creation of these batteries adds to the growing body of research that utilizes fungi in various applications, such as clothing, housing, and meat alternatives.
In addition to the Swiss researchers' work, scientists in Austria have developed myceliotronics, which are electronic components made from mushrooms. These components can be used as flexible circuit boards, casings, and separators for zinc-carbon batteries. The mycelium skin of a tree fungus acts as the substrate, making up around 37% of the circuit board's mass. This skin is harvested and covered with a copper layer, then galvanized with gold to create traces, the circuit board equivalent of wires. The porous structure of the mushroom makes it an effective battery separator.

Mushrooms can be used to infect and control insects
Mushrooms are the fruiting bodies of fungi that obtain their energy by decomposing dead or decaying organic material. Fungi do not depend on light for energy, unlike plants, and can easily grow in the dark.
Some mushrooms, like Ophiocordyceps unilateralis (commonly known as the zombie ant fungus), are parasitic and infect insects. This fungus is usually found in tropical rainforests and infects ants from the Camponotini tribe, including carpenter ants. The fungus enters the insect through spores that attach to their exoskeletons and eventually break through using mechanical pressure and enzymes. The spores then grow through the bodies of the insects, making them faster, stronger, and more aggressive. The fungus also alters the behaviour of the infected insect, making it leave its nest and attach itself to the underside of a leaf, an area suitable for fungal growth. The insect then dies, and the fungus grows into a fully-fledged fruiting body that sprouts from the insect's flesh. This behaviour is termed the "death grip".
Another example of a parasitic fungus is Cordyceps, which also infects insects through spores. These mushrooms contain a bioactive compound called cordycepin, which has the potential to be developed into powerful new antiviral medications and cancer drugs.
These fungi can control insect brains and manipulate their behaviour to reach death locations that are optimal for spore dispersal. They can alter the accumulation of dopamine and other chemicals in insects, thereby causing precise behavioural manipulation.

Mushrooms can be used to accelerate decomposition
Mushrooms are the fruiting bodies of fungi, which obtain their energy by decomposing dead or decaying organic material, such as fallen leaves or dung. Mushrooms can break down organic matter and absorb energy through mycelium, which consists of thread-like hyphae. This process of decomposition can be accelerated by mushrooms, as they can grow on dying organic matter and cause the surrounding area to deteriorate and rot.
The ability to accelerate decomposition can be further enhanced by manipulating the growth and spread of spores, which contain internal energy storage that enables them to germinate and initiate the decomposition process. By controlling the spores, one can influence the speed and extent of decomposition.
In addition to their role in decomposition, mushrooms have recently been explored for their potential in generating electricity. Scientists have discovered that certain bacteria, such as cyanobacteria, can be combined with mushrooms to create a mini energy farm. This is achieved by 3D printing the bacteria onto the curved surface of a mushroom, allowing the microbes to capture energy from light and produce an electric current. While the amount of electricity generated is currently small, it showcases the potential of mushrooms in sustainable energy production.
Furthermore, mushrooms have been used in innovative ways, such as in the creation of "mushroom batteries." Swiss researchers have taught fungi to generate electricity by mixing fungal cells with 3D printing ink, resulting in a biodegradable battery. This technology could be particularly useful for powering devices in remote regions, such as temperature sensors for agricultural or research purposes.
Overall, mushrooms play a significant role in accelerating decomposition, and their unique abilities continue to be explored for various applications, including sustainable energy solutions.
