Freeze drying or ultraviolet light exposure are other ways to inhibit mold growth, although they do not kill mold spores permanently. Eliminating mold through these methods is challenging due to paper degradation caused by light exposure over time. There are also some mold species that have preferences for colder temperatures.
Dry rot is spread by spores which are present in most buildings. The minimum moisture content of timber for spore germination is 28–30% (lower than other rots), and the relative humidity must be in excess of 95%. Spores are resistant to desiccation and may still be viable for germination when they are several years old. [2]
Mold allergies are present in a minority of the population that is genetically predisposed to mold, and usually this allergy is not life threatening. Black molds, or so called toxic molds, can ...
The thermal death point, which is defined as the lowest temperature that can kill all cells in ten minutes, is 60 °C. [7] Rhizopus stolonifer can grow in acidic environments with a pH of as low as 2.2. The pH range can vary from 2.2 to 9.6. [9] Ultraviolet irradiation can delay spore germination. [10]
The body of mold consists of a thread-like root that invades the food, a stalk that rises above the food and may not be visible to the naked eye, and spores that form at the end of the stalks ...
[10] Spores need three things to grow into mold: nutrients – cellulose (the cell wall of green plants) is a common food for indoor spores; moisture – to begin the decaying process caused by mold; and time – mold growth begins from 24 hours to 10 days after the provision of growing conditions.
