A hangar for Cargolifter built at Brand-Briesen Airfield. The hangar (360 m long, 220 m wide and 106 m high), is a technological marvel in itself, is a freestanding steel-dome barrel-bowl construction large enough to fit the Eiffel Tower on its side.
General Definition. Mold spores are microscopic, multi-cellular organisms that reproduce asexually. Molds are fungi, similar to yeasts and mushrooms, and they can grow in any environment with a constant source of moisture. During the growth process, mold spores begin to undergo chemical reactions that allow them to devour nutrients and multiply. These chemical reactions cause fumes to be released into the atmosphere.
Molds may also reproduce by means of sexual spores such as ascospores and zygospores, but this is not common. The form and manner in which the spores are produced, along with the appearance of the hyphae and mycelium, provide the main criteria for identifying and classifying molds.
