Mold spores are often spherical or ovoid single cells, but can be multicellular and variously shaped. Spores may cling to clothing or fur; some are able to survive extremes of temperature and pressure. Although molds can grow on dead organic matter everywhere in nature, their presence is visible to the unaided eye only when they form large ...
The spores are wind-dispersed and they are often extremely abundant in outdoor air. Indoors Cladosporium species may grow on surfaces when moisture is present. Cladosporium fulvum, cause of tomato leaf mould, has been an important genetic model, in that the genetics of host resistance are understood. [4]
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. Mold colonies can grow inside buildings, and the ...
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 ...
Mold illness isn’t easy to define, and the path from home mold growth to debilitating chronic health symptoms is complicated. But often the story starts like this: Moisture in a home can cause ...
Cladosporium cladosporioides is a darkly pigmented mold that occurs world-wide on a wide range of materials both outdoors and indoors. It is known for its role in the decomposition of organic matter and its presence in indoor and outdoor environments.
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
A variety of other mold species, such as Penicillium or Aspergillus, may appear to grow on non-cellulosic surfaces but are actually growing on the biofilm that adheres to these surfaces. Glass, plastic, and concrete provide no food for organic growth and as such cannot support mold or mildew growth alone without biofilm present.
