Disaster recovery and restoration can be veiled in mystery to the many who have not undertaken specific training. This glossary explains technical terms to assist both report writing and the understanding of those technical terms so often misunderstood.
Definition
| Alternaria: |
Common outdoor fungi found in soil. Alternaria's primary growth season is late summer and early autumn. Alternaria is an allergen. |
| Environmentally Adaptive Fungi: |
Any number of fungi that are common to outdoors and are not common growth elements in healthy buildings. Air samples will indicate many of the fungi that are common outdoors, are brought into a building from building occupants, air currents and ventilation. Education Note: Environmentally adaptive fungi are those outdoor fungi, which under the right growth conditions (temperature and humidity), take hold and grow indoors on nutrient rich building materials. Cladosporium and Alternaria are fungi which grow mainly on above ground on dead organic material. They are adaptable indoors when the indoor nutrient requirements are ideal. Other environmentally adaptive fungi are Aspergillus and Penicillium, which are prevalent in the tracked in soil and airborne dusts. Both Aspergillus and Penicillium contain species that will grow well on indoor building materials and contents, when ideal temperatures and humidity exist. See Environmentally Adaptive Bacteria |
| Viable Fungi Colours: |
When fungi and molds are alive they are multi-colored from red, pink to orange. Some common examples are: Black Color Fungi - Alternaria, Chaetomium, Ulocladium and Stachybotrys. Stachybotrys produces a very deep black to dark purple color. Green Color Fungi - Aspergillus and Penicillium species. When these species sporulate, they turn a velvety green. The mycelia growth itself, is typically white. White Color Fungi - Fusarium, yeasts and mycelia growth, indicating the start of mold growth or young non-sporulating growth, such as identified on Acremonium, Aspergillus and Penicillium, during their youth growth cycle and before maturity. |
