Penicillium (most commonly P. Chrysogenum, which seems particularly well-adapted to infiltrating the air of residences and buildings), can usually be located either: Though P. Chrysogenum is not usually the most virulently toxic strain of Penicillium, it does produce a number of toxins of moderate toxicity and it is highly allergenic. Resistant isolates were naturally occurring in packinghouses and were not associated with crop losses. Penicillium can, however, also be an airborne threat; many species have been found present in the air and dust of residences and public buildings. Consuming foods which have been contaminated with Penicillium is risky owing to the fact that many species produce highly toxic mycotoxins. Herein, the effects and mechanisms of 2-methoxy-1,4-naphthoquinone (MNQ) as a potential inhibitor of P. digitatumwere studied. Research on the storability of clementine fruits: effect of clone and rootstock on the development of rots in cold storage. According to Wikipedia, “The fungus can be readily transported from the outdoors, and grow indoors using building material or accumulated soil to obtain nutrients for growth.” And, once spores are carried indoors, they easily become established thanks to their low moisture needs: “Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface.” This is particularly likely to happen in areas where rainfall is heavy, such as the coastal United States or the UK; a British study found that Penicillium spores were so prevalent in the indoor air of residential properties they sampled that spore levels indoors actually exceeded outdoor levels by 16 percent. There are 200 species of Penicillium known. Penicillium also produces a range of mycotoxic acids, such as penicillic acid and cyclopiazonic acid; both of these have acute toxic effects in mammalsthey have been shown to be the casual agents of liver and kidney lesion… PHI-8 11Æ432 3Æ78 Alternaria sp.
