Penicillium Mold Inspection Information Penicillium
Some Penicillium species are fairly common indoor fungi, even in clean environments. This particular specie of fungi can proliferate in abundance in indoor environments. P. species can be found at the sub-basement levels offices and rooms, in libraries, auditorium, storage room of paper materials and also in ventilation systems. Some P. species can produce small, nondescript conidia and complex mixtures of metabolites that are more or less toxic.
Like other molds, spores have the highest concentrations of mycotoxin, although the vegetative portion of the mold, the mycelium, can also contain the poison.
Disease - Exposure to the various penicillium toxin can result in the following ill health effects:
-
Patulin, a toxin from P. expansum: cytotoxic and/or carcinogenic
-
Citrinin, a toxin from P. citrinum, expansum & viridicatum: nephrotoxic
-
Ochratoxin, a toxin from P. cyclopium & viridicatum: nephrotoxic
Poria
Two major differences between poria and ordinary decay fungi are that ordinary decay fungi require the structure to provide the water (green wood, rain and plumbing leaks, condensation), while poria provides its own water through rhizomorphs connected to moist soil outside the structure, and poria dies quickly when deprived of water, while ordinary decay fungi usually just go dormant. These differences make both the detection and control of poria very different from those of ordinary decay fungi. An inspector who does not accurately diagnose poria infection can make a company responsible for repairing extensive decay, including that already repaired, within less than a year; or, in the extreme, razing and rebuilding the entire structure.
