Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [ 1 ] Aspergillus penicillioides is typically found in indoor air, house dust , and on substrates with low water activity , such as dried food, papers affected by foxing , and inorganic objects such as binocular lenses. [ 2 ]
“Most people say, ‘Aspergillus and Penicillium are the bad kinds of mold, so you just have to find them and remove them,’ but that’s not true,” Peccia says. “It’s way more ...
In 1975, Woolf et al. [32] proposed that the inherited disorder phenylketonuria protects against ochratoxin A poisoning through the production of high levels of phenylalanine. Ochratoxin is a competitive inhibitor of phenylalanine in the phenylalanyl-tRNA-synthetase-catalyzed reaction thus preventing protein synthesis, which can be reversed by ...
Health problems associated with high levels of airborne mold spores include allergic reactions, asthma episodes, irritations of the eye, nose and throat, sinus congestion, and other respiratory problems. [22] Several studies and reviews have suggested that childhood exposure to dampness and mold might contribute to the development of asthma.
The three molds include aspergillus, penicillium and cladosporium. The report states the mold growth is "indicative of a catastrophic loss of HVAC functionalities leading to atmospheric disruption."

All are produced by Penicillium and Aspergillus species. The three forms differ in that Ochratoxin B (OTB) is a nonchlorinated form of Ochratoxin A (OTA) and that Ochratoxin C (OTC) is an ethyl ester form Ochratoxin A. [18] Aspergillus ochraceus is found as a contaminant of a wide range of commodities including beverages such as beer and wine.
Ochratoxins are a group of mycotoxins produced by some Aspergillus species (mainly A. ochraceus and A. carbonarius, but also by 33% of A. niger industrial strains) and some Penicillium species, especially P. verrucosum. Ochratoxin A is the most prevalent and relevant fungal toxin of this group, while ochratoxins B and C are of lesser importance.
