It is also toxic to mammals, as proven by rodent studies: “At relatively high doses, patulin is acutely toxic in mice and rats, causing gastrointestinal lesions, distension and haemorrhage in the stomach and small intestine… LD50 values (lethal dose) of 20-100 mg/kg bodyweight have been reported for patulin administered orally to mice and rats.” (. There are 200 species of Penicillium known. The name penicillium originates from Latin to mean painters brush because of the structure of the conidial spores which are fluffy in appearance. The common occurrence of Penicillium species in food is a particular problem. Exposure to mold in the home is not good for your health, even if it is the kind of mold that antibiotics are made from. Because of their small size, they take long to settle and can be inhaled deep into the lungs.

The zone immediately around the mold—later identified as a rare strain of Penicillium notatum—was clear, as if the mold had secreted something that inhibited bacterial growth. Other species of Penicillium are useful in the food and drug industry and have beneficial effects of humans. on ceiling tiles by John C.S. In decaying organic matter: Plant debris and spoiled food provide an ideal environment for Penicillium, so compost heaps, improperly kept houseplants, and spoiled food should always be removed from the indoor environment as soon as possible. It is also found in paint and compost piles. Growing in cellulose materials within homes and buildings (e.g. Indoor air sampling for mould spores may be conducted to help in evaluating the air quality after occupants’ complaints of ill health, to determine the effectiveness of remediation procedures, to assess health hazards or to proactively monitor indoor air quality. Penicillium – This mold genus includes hundreds of species, some of which are used to produce the antibiotic penicillin.

Please click for the rest of my pages on fungi Penicillium chrysogenum (also known as Penicillium notatum) is the source for penicillin, the first antibiotic. While it is relatively easy to identify Penicillium which has grown extensively on stored food items thanks to the mold’s often vivid blue-green or yellow color, properly identifying the various types of this mold which may infiltrate indoor air is far more challenging. ; Microscopically, P. chrysogenum shows typical filamentous hyphae with conidia, which are the asexual spores of the fungi. Usually only one of those features of P. chrysogenum – the drug-making one – is considered beneficial to humankind, but I would argue that it being common also does us a favor. Citreoviridin: Citreoviridin has been shown to have strongly neurotoxic effects at high doses; in lab animals, exposure has been demonstrated to cause paralysis in the extremities, followed by convulsions and respiratory arrest. Commonly found in soil, food, cellulose and grains (17, 5). There are more than 200 known species and most of them grow quickly and spread easily from one place to another.

Animals were fed a control diet first, and an increase in weight proved the formulation to be satisfactory. However, about ten percent of people may be allergic. This process of identification will, however, only be able to tell you that you are dealing with a species of Penicillium, not which species exactly or what type of mycotoxins it is producing. Other species can produce toxins that damage internal organs and are potential carcinogens. Penicillium also produces a range of mycotoxic acids, such as penicillic acid and cyclopiazonic acid; both of these have acute toxic effects in mammals—they have been shown to be the “casual agents of liver and kidney lesions in mice fed with contaminated corn.”[11].

Penicillium chrysogenum as a model system for studying cellular effects of methylglyoxal. Damp building materials and items like books, boxes, and wood stored in moist basements are a particular hazard. The antifungal protein of Penicillium chrysogenum (PAF) inhibits the growth of important pathogenic filamentous fungi, including members of the Aspergillus family and some dermatophytes. Penicillium mold is like other types of mold, it can cause structural damage and health concerns if its rapidly growth. Penicillium chrysogenum is the most common specie found in indoor environments and is responsible for many allergic reactions in those with a sensitivity. The patient underwent a second pulmonary right lobectomy and was successfully treated with oral itraconazole. Since the discovery of penicillin from Penicillium chrysogenum, scientists have continued to search for new antibiotics produced by filamentous fungi belonging to the phylum Ascomycota.More recently the potential of fungi as producers of mammalian enzyme inhibitors has been recognized.
