Water-soluble mushroom compounds include polysaccharides and beta-glucans, which are known for their immunomodulatory and antioxidant properties. Beta-glucans, for example, have demonstrated promising anticancer effects in animal studies and limited clinical trials through their immunomodulatory activities. Additionally, water-soluble mushroom glucans have been shown to induce TNF-α production and increase proliferation without excessive inflammation in resident macrophages.
The extraction of these water-soluble compounds from mushrooms can be challenging due to the robust structure of hyphae cells. Traditional methods such as Soxhlet and reflux extraction, supercritical carbon dioxide (sCO2), and agitated organic solvent techniques are often time-consuming and energy-intensive. However, alternative methods like ultrasound-assisted extraction (UAE) have emerged as promising techniques for producing water-soluble mushroom extracts.
One company, Vesper Mushrooms, utilizes an ethanol-water extraction process to create water-soluble mushroom extracts. They claim that this method captures a full spectrum of beneficial molecules, including both water-soluble and alcohol-soluble compounds. Their extracts are designed to be easily mixable into various beverages, such as coffee, tea, smoothies, juices, soups, and broths, without affecting their consistency.
Water-soluble mushroom extracts offer better control over the final product's composition, resulting in stronger effects and greater benefits. They can be produced in liquid or powdered forms, providing flexibility in their usage. Furthermore, water-soluble mushroom polysaccharides have been studied for their potential in treating and preventing chronic diseases by reducing oxidative stress levels.

Culinary uses of mushroom oil
Mushrooms have long been valued in culinary traditions worldwide for their rich flavours and potential health benefits. The extraction of oils from these fungal organisms has opened up a realm of possibilities for researchers, culinary experts, and health enthusiasts.
Mushroom oil is rich in essential fatty acids like linoleic acid, oleic acid, and palmitoleic acid, which are integral to a balanced diet. The presence of these fatty acids in mushrooms means they can be seamlessly integrated into various culinary dishes, enhancing both flavour and nutritional content.
The distinct "mushroom flavour" is attributed to the presence of 1-octen-3-ol, which is identified through extraction methods like hydrodistillation and solvent-assisted flavour evaporation (SAFE). The unique nutritional and flavour profiles of mushroom oils enhance gastronomic experiences.
Mushroom oils can be used in cooking, as well as in salad dressings, providing a delectable means of obtaining beneficial fatty acids. They can also be added to coffee or tea, smoothies and juices, soups and broths, without affecting the consistency of the final product.
Some specific culinary uses of different types of mushrooms include:
- Enoki mushrooms, with their long stems and white colour, are often used in Asian cuisine, especially in soups. They add a crunch to salads and sandwiches and a mild flavour to soups and stir-fries.
- Morel mushrooms, with their honeycomb-like shape and intense, deep woods flavour, can be cooked by sautéing, stuffing, or simmering to create flavorful sauces.

Mycoremediation with mushrooms
Mycoremediation is a process that uses mushrooms and fungi to remove waste from the environment. The term is derived from the ancient Greek "mukēs", meaning "fungus", and the Latin suffix "-remedium", meaning "restoring balance". It is a form of bioremediation, which involves the use of biological methods to remediate waste. Mycoremediation has been proven to be an effective, environmentally friendly, and cheap solution for removing a wide range of contaminants from the environment, including heavy metals, organic pollutants, textile dyes, leather tanning chemicals, wastewater, petroleum fuels, polycyclic aromatic hydrocarbons (PAHs), pharmaceuticals, and pesticides.
Mushrooms have been used for consumption for a long time due to their flavour and protein content. However, they are also effective tools for mycoremediation because of their ability to degrade various types of pollutants through enzymatic processes. The enzymes produced by mushrooms facilitate the breakdown of complex molecules into simpler ones like CO2, H2O, and NO3 through a process called biodegradation. This process not only removes pollutants but also transforms them into less toxic products, making the environment safer.
One specific mushroom, the oyster or Pleurotus ostreatus, has been found to possess remarkable water purification capabilities. In a lab-based study, oyster mushroom mycelia successfully removed E. coli from water, achieving a 99.25% removal rate in water made in the lab and a 99.74% removal rate in water taken directly from the Chicago River. Additionally, fungal filters made from mycelial networks have been employed to tackle contaminated water runoff from farms. These filters act as micro-filtration systems while simultaneously releasing enzymes that break down toxic contaminants.
Mycoremediation has also proven effective in addressing the toxic ash and reactive oxygen species resulting from wildfires. For example, in California, hay bales filled with oyster mushroom mycelium were used to clear heavy metals, harmful PAHs, and even TNT from water sources, preventing them from reaching publicly accessible water collections. Furthermore, mycoremediation can be applied to soil contaminated with petroleum-based substances. Mushrooms can break down these contaminants and transform them into non-toxic compounds, allowing them to be safely composted back into the soil.
While mycoremediation offers significant benefits, it is important to consider potential drawbacks. One disadvantage is the time required for mushrooms to adapt to their environment and effectively remediate wastes. Additionally, mushrooms cultivated on industrial wastes may exhibit toxicity or genotoxicity due to the presence of genotoxicants in the waste used for their growth. Therefore, assessing the toxicity and genotoxicity of mushrooms intended for mycoremediation is crucial to ensure their safe and effective use.
