Featured. Molds are a large and taxonomically diverse number of fungal species in which the growth of hyphae results in discoloration and a fuzzy appearance, especially on food. Growth rates of xerophilic species closely related to X. bisporus, viz. There are multiple avenues of exposure to the toxic and allergenic components of microorganisms. Step #1. To investigate the competitive characteristics of X. bisporus at low a(w), both X. bisporus strains were grown in dual-culture with xerotolerant species Aspergillus flavus and Penicillium roqueforti, and xerophilic species A. penicillioides, C. inops, C. xerophilum and Eurotium chevalieri, on glucose-fructose agar plates at 0.94, 0.84, 0.80 and 0.76 a(w) and at 25 C. This mold, xerophilic, can from time to time be found on chocolate, dried fruits and baked goods. The Xerophilic types of fungi grow in drier conditions, with only minimal moisture. Optimal conditions for growth of both X. bisporus strains were approx. In the majority of cases where Stachybotrys is found indoors, water damage has gone unnoticed or ignored since it requires extended periods of time with increased levels of Black mold is the most commonly known name of toxic mold among the public.

Water activity (aw) is measured as the humidity above a substance relative to the humidity above pure water (Aw = 1.0). Some molds require relatively very low levels of available moisture for them to grow. For instance, droughts weaken plants, making them more susceptible to damage and infestation (11, 13).
