Molds (sometimes called moulds or mildew) are a diverse subgroups of fungi, a classification which also includes mushrooms, yeasts, rusts and smuts. The term mold usually refers to fungi that appear as woolly or powdery growths on stored fruits or grow in damp areas of the home (e.g., bathrooms). Although molds are often viewed as food spoilers and causers of plant and human diseases, they, like bacteria, are natures organic decomposers in the biotic food chain. Molds are also used in the production of certain foods (e.g., bread, cheese, mushrooms), alcohol, and antibiotics. Under optimal conditions, a single mold spore can germinate and produce a fungal colony with hundreds of thousands of spores in 4 to 9 days. To grow and thrive a fungus requires organic matter and water. The organic matter can almost be any carbon-containing material, such as plant matter, cotton, wood, hemp, wool, leather, soil, house dust or paints. Water can be in the form of standing water, condensation, dampness, or high humidity. Fungi can survive in humidity ranges from 0% to 100% but flourish in the 65% to 85% range. Most allergenic molds release their spores into the atmosphere during dry conditions (humidity below 70%); however, some allergenic fungi (certain mushrooms and Ascomycetes) prefer an environment with high humidity for spore release. Mold allergy is similar to pollen allergy in its symptoms and treatment. However, the growth and spore dispersal of many molds are not as seasonal as that of pollen, and most molds can grow indoors as well as outdoors. People who are allergic to molds may have symptoms that persist for long periods of time, recur several times throughout the year, or are associated with specific environments where molds flourish. Indoor Mold Spores Mold colonies may not be large or colorful enough to be seen with the naked eye, but mold growth should be suspected in the following locations: Areas where musty or ...
