Cultures of Penicillium expansum produce a musty, earthy odor. Geosmin [1,10-trans-dimethyl-trans(9)-decalol] was identified by gas chromatography-mass spectrometry from headspace samples of P. expansum cultures. Olfactory comparison of P. expansum cultures with a geosmin standard indicated geosmin is the primary component of the odor associated with P. expansum.

Sixty isolates of Penicillium expansum were tested for patulin production in decaying apples. All the isolates were found to produce the mycotoxin patulin as determined by thin-layer chromatography. Since patulin is known to be stable in many apple products, the results indicate that apple products made partially from apples decayed by P. expansum will contain patulin which may present a health...

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 ...

در حال حاضر اندازه گیری شدت بیماری در مراکز پژوهشی با استفاده از وسایل دستی و یا از طریق مقیاس دهی چشمی بیان می شود. با گسترش چشم گیر علوم رایانه ای در اندازه گیری دقیق و سریع شدت بیماری، پژوهشی به منظور ارزیابی پتانسیل کنترل بیولوژیک دو مخمر pichia guilliermondii (a6)وcandida membranifaciens (a4)در تلفیق با سیلیکون (si) در غلظت های 1/0%، 3/0% و 5/0% و ترکیب آن ها در کنترل جدایه های p1 و p2 از ...

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...

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...

Among the species that cause blue mold, isolates of Penicillium expansum are the most prevalent and virulent species, causing more than 50 percent of postharvest decay. We report the draft genome sequence of P. expansum R19 in order to identify fungal virulence factors and to understand the mechanism of infection.

Fungicides are the most common agents used in postharvest treatment of fruit and are the most effective against blue mould, primarily caused by Penicillium expansum. Alternatively, blue mould can be treated with antagonistic microorganisms naturally occurring on fruit, such as the bacterium Gluconobacter oxydans. The aim of this study was to establish the antifungal potential of the G. oxydans ...
