The domain of agriculture is undergoing an evolution, extending its boundaries beyond Earth’s soil and venturing into space research. At the convergence of this evolution is a subject matter often overlooked: Fungi. This paper explores the role of fungi in diverse sectors such as organic farming, humidity control, and even extraterrestrial research, to demonstrate their multi-faceted potential. Drawing upon academic research, permaculture principles, and polysaccharides, the intricate relationships between these areas will be dissected.


The indispensable role of fungi in terrestrial ecosystems is well-known. Their capabilities in decomposing organic matter, forming symbiotic relationships with plants, and even in culinary arts cannot be overstated (Smith and Read, 2008). Nevertheless, the application of fungi reaches beyond the earthly to the cosmic—specifically in the role of space agriculture and sustenance in outer space environments (Horneck et al., 2010).

Humidity Control and Grain Jars

Fungi require specific environmental conditions for optimal growth. One of the critical factors is humidity, which can be regulated through various methods such as grain jars. These jars contain a substrate such as rye or wheat berries, which provides the necessary nutrients and water retention for fungal growth (Stamets, 1993). Humidity control is essential in avoiding undesirable mold or bacterial growth and ensuring the cultivation of the desired fungal species (Ritz and Trinci, 1993).

Permaculture and Organic Farming

In the realm of agriculture, fungi offer a sustainable alternative for food production and soil health. Through the principles of permaculture, which advocate for mimicking natural ecosystems, fungi can be incorporated into organic farming practices. They aid in soil aeration and act as mycorrhizal partners for various plants (Ferguson and Jeffries, 2001). Their root-like structures, or mycelium, provide a network that helps in water retention and nutrient cycling (Jones et al., 2009).

Polysaccharides and Nutrient Absorption

Mycelium produces complex polysaccharides, which are crucial in water absorption and in forming biofilms. These polysaccharides contribute to the structural integrity of the fungal cell wall and also have industrial applications, such as in the production of biodegradable plastics (Rinaudo, 2006).

Fungi in Space Research

A groundbreaking sector that has shown interest in fungi is space research. Given the extreme conditions of outer space, self-sustaining biosystems are crucial for long-term missions. Experiments with Pleurotus ostreatus have indicated that they can grow on a diet of organic waste, thereby recycling waste while producing edible biomass (Blattnig et al., 2011). Moreover, fungal mycelium can adapt to low-humidity environments, which is invaluable in spacecraft where maintaining high humidity is problematic (Wamelink et al., 2019).

Cooking with Mushrooms

The versatility of fungi is not merely confined to technical or scientific applications. In the culinary arts, mushrooms have emerged as a source of complex flavors, meat substitutes, and even as sources of vitamins and minerals (Cheung, 2010). Edible mushrooms such as Agaricus bisporus are rich in polysaccharides and can be a part of various cooking methods from sautéing to grilling (Kalač, 2016).


A multi-disciplinary approach to fungi shows their applications stretching from the microscopic to the macroscopic, from Earth’s permaculture to the distant horizons of outer space. Whether it is the humidity control in grain jars or the involvement of polysaccharides in nutrient cycling, fungi have proven to be resourceful entities in both organic farming and scientific research.


From the soil under our feet to the life-support systems of future space missions, fungi act as silent partners in our journey towards a sustainable future. Through interdisciplinary collaboration and research, we can unravel the full spectrum of possibilities that fungi offer, enriching both our understanding and application of this extraordinary kingdom.
