What is Mold?
Mold (or mould) is a term used to refer to fungi that grow in the form of multicellular thread-like structures called hyphae. Fungi that exist as single cells are called yeasts. Some molds and yeasts can cause health effects and food spoilage, others play an important role in biodegradation or in the production of various foods, beverages, antibiotics and enzymes.
Mold is also found in damp building materials where it often appears like stains and comes in a variety of colors. A must smell is an indication of microbial growth even when there is no visible growth.
Mold growth requires moisture. The sources of moisture could be washing, cooking, air humidifiers, condensation or leaks from plumbing or from the outside. Poor ventilation contributes to higher humidity levels and leads to condensation, which also allows mold growth.
