Molds can also pose a hazard to human and animal health when they are consumed following the growth of certain mold species in stored food. Some species produce toxic secondary metabolites, collectively termed mycotoxins , including aflatoxins , ochratoxins , fumonisins , trichothecenes , citrinin , and patulin .
In addition to growth on carbon sources, many species of Aspergillus demonstrate oligotrophy where they are capable of growing in nutrient-depleted environments, or environments with a complete lack of key nutrients. Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation ...
S. chartarum is a slow-growing mold that does not compete well with other molds. It is only rarely found in nature, sometimes being found in soil and grain, but is most often detected in cellulose-rich building materials, such as gypsum-based drywall and wallpaper from damp or water-damaged buildings.
Outdoors, molds play an important role in breaking down organic matter like decaying leaves, but inside, mold can spoil foods or grow on damp surfaces and should be avoided, according to the EPA ...
Meiosis occurs during spore development, resulting in haploid dormant spores. Upon exposure to moist nutrient conditions, the spores develop into amoebae, or, in aqueous suspension, into flagellates. The life cycle is completed when haploid amoebae of different mating types fuse to form a diploid zygote that then develops by growth and nuclear ...
Thus, the concept of mold growth, assessment, and remediation is essential in preventing health issues arising due to the presence of dampness and mold. Molds may excrete liquids or low-volatility gases, but the concentrations are so low that frequently they cannot be detected even with sensitive analytical sampling techniques.
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 ...
Mold is a natural part of the environment and plays an important part in nature by breaking down dead organic matter such as fallen leaves and dead trees; indoors, mold growth should be avoided. Mold reproduces by means of tiny spores .
