The fungi isolated from 100 samples of flue-cured tobacco from 12 markets in 2 tobacco belts comprised 11 genera, including 10 species of Aspergillus. The mean percentage per sample isolated from 62 samples of tobacco from Middle Belt markets was Alternaria, 40.6%; Aspergillus niger, 47.8%; Aspergillus repens, 38.0%; and Penicillium, 25.8%. The mean percentage per sample isolated from 38 sample...

Two species from the genus Penicillium, Penicillium expansum and P. griseoroseum (Brasilian isolates) were characterized morphologic and molecularlly. Morphological variability was detected among isolates in regard to colony morphology and to conidia coloration. The molecular characterization was based on the RAPD markers, telomeric fingerprinting and ITS sequencing. A total of 78 RAPD primers ...

The Penicillium roqueforti group has recently been split into three species, P. roqueforti, Penicillium carneum, and Penicillium paneum, on the basis of differences in ribosomal DNA sequences and secondary metabolite profiles. We reevaluated the taxonomic identity of 52 livestock feed isolates from Sweden, previously identified by morphology as P. roqueforti, by comparing the sequences of the r...

I t has been known for some time that Penicillium citrinum Thom when grown on suitable media produces a characteristic lemon yellow colour. Thus Thom in his monograph on “ Cultural Studies of species of 1910), says, “ P. citrinum produces a lemon yellow colour, soluble in alcohol, in media containing sugars, milk, gelatin, bread and potato.” This colouring matter was not isolated, however, nor ...

Grape fruits with blue mold symptoms were collected from house storages in different locations in Korea and were investigated for their association with Penicillium species. A total of 12 isolates of Penicillium were isolated from the collected fruits. Based on morphological and cultural characteristics and β-tublin gene sequence data analysis, they were identified as P. bialowiezense, P. citri...

In the indoor environment, people are exposed to several fungal species. Evident dampness is associated with increased respiratory symptoms. To examine the immune responses associated with fungal exposure, mice are often exposed to a single species grown on an agar medium. The aim of this study was to develop an inhalation exposure system to be able to examine responses in mice exposed to mixed...

Mycotoxins are secondary metabolites produced by several fungi, more specifically those of the genera Aspergillus, Fusarium and Penicillium. They were discovered in the early 1960s, when more than 100,000 young turkeys died in the United Kingdom from an apparently new disease, which was named "turkey × disease". The toxin-producing fungus was identified as A. flavus and the toxin was given the ...

In a survey on the biodiversity of Penicillium species in soils of the National Park of Urmia Lake (NW Iran), eight Penicillium isolates were isolated as members of the section Citrina. Based on a combination of cultural and morphological criteria, the isolates were identified as Penicillium anatolicum, P. sanguifluum,and P. sizovae. The identity of each species was further confirmed using sequ...
