As a mycologist with extensive experience in studying the biology and ecology of fungi, I am well-equipped to address the question of whether fungi require oxygen for growth. Fungi, a diverse group of organisms that include yeasts, molds, and mushrooms, are heterotrophic, meaning they obtain their nutrients from external sources. They are capable of growing in various environments, from the soil to the human body, and even in extreme conditions such as the Arctic and the deep sea.
The life cycle of a fungus typically involves the absorption of nutrients from its surroundings, which are then converted into energy through metabolic processes. Oxygen plays a crucial role in this process, particularly for aerobic respiration, which is the process by which many fungi generate energy. During aerobic respiration, oxygen is used to break down organic molecules, releasing energy in the form of adenosine triphosphate (ATP), which is essential for the fungus's growth and reproduction.
However, it is important to note that not all fungi are obligate aerobes; some are facultative anaerobes, meaning they can switch between aerobic and anaerobic respiration depending on the availability of oxygen. In anaerobic conditions, these fungi can utilize alternative pathways, such as fermentation, to generate energy, albeit less efficiently than aerobic respiration.
In indoor environments, the availability of oxygen is generally sufficient for the growth of most fungi. The air we breathe is composed of approximately 21% oxygen, which is more than adequate for the respiratory needs of most fungi. However, the growth of fungi is not solely dependent on oxygen; other factors such as temperature, humidity, and the presence of suitable substrates also play significant roles.
For instance, some fungi thrive in damp and humid conditions, which are conducive to their growth and spore dispersal. The presence of organic matter, such as wood, paper, or fabrics, provides a substrate for fungi to colonize and extract nutrients. Additionally, certain fungi are adapted to specific environmental conditions and may require specific temperatures or pH levels to grow optimally.
In summary, while oxygen is a critical component for the growth of many fungi, especially those that rely on aerobic respiration, it is not the only factor that determines fungal growth. The interplay of various environmental factors, including oxygen, temperature, humidity, and the availability of nutrients, all contribute to the successful establishment and proliferation of fungal species.

Fungi, like all living organisms, require three essential factors for life: air, food and water. Fungal growth in the indoor environment is dictated by the availability of these three factors. Just like humans, what most fungi "breathe" is oxygen, which is generally abundant in indoor environments.
