Mold growth is primarily supported by a moist environment, which can be a result of high humidity, dampness, and a lack of ventilation, especially in sealed conditions like long-term storage of a casketed body.
The condition which favors or supports mold growth is primarily a moist environment. Mold thrives in areas where there is high humidity or dampness, which can be caused by a lack of proper ventilation, leaks, or condensation. Situations like the long-term storage of a casketed body can create such an environment, especially if the area is sealed and prevents the evaporation of moisture.
Storage of food or laboratory materials like cultures also requires careful control of moisture to prevent mold growth. Furthermore, the presence of organic material serves as a food source for mold, and darkness can also provide a favorable condition for many types of mold to proliferate.
Other contributing factors mentioned include air conditioning systems that can incubate bacteria and mold, exposure to sources of mold such as houseplants, soil, and surrounding gardens, and the impact of elements such as pollen and dust.
In reference to other biological occurrences, water molds are a specific type of mold that live in water or moist soil and are parasites of plants and animals, further emphasizing the link between moisture and mold growth. Considering this information, the condition most supportive of mold growth with regard to the long-term storage of a casketed body would be a moist environment.
