How Mold Grows on Inorganic Surfaces
While mold cannot directly get nutrients from inorganic materials like concrete, glass, metal, or plastic, it can grow on these surfaces under certain conditions. If a microscopic layer of organic nutrient, such as dust layers containing carbon sources like human skin, pet dander, insect waste, and dirt, develops on the surface of these inorganic materials, mold can grow This is because these organic materials provide the necessary nutrients for mold growth.
Therefore, even though the surface is inorganic, the presence of organic nutrients in the dust layer allows for mold growth. It’s important to note that moisture is a key factor in this process. Without a source of moisture, mold cannot grow. So, keeping surfaces clean and dry is crucial in preventing mold growth.
