Identification of geosmin as a volatile metabolite of Penicillium expansum.
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.
متن کاملIdentification and characterization of LysM effectors in Penicillium expansum
P. expansum is regarded as one of the most important postharvest rots of apple fruit and is also of great concern to fruit processing industries. Elucidating the pathogenicity mechanism of this pathogen is of utmost importance for the development of effective and safe management strategies. Although, many studies on modification of the host environment by the pathogen were done, its interaction...
متن کاملProduction of patulin by Penicillium expansum.
Twenty-seven isolates of Penicillium expansum Lk. ex Thom obtained from Europe, Australia, and North America from seven different fruit hosts all produced patulin in culture. Six isolates were essentially nonpathogenic in apple fruits. In culture, patulin generally accumulated to much higher levels than in apple fruits. At all temperatures permitting fungus growth, patulin was produced. However...
متن کاملIdentification of Ethylene as a Volatile Product of the Fungus Penicillium Digitatum.
Experiments reported independently by BIALE (1) and MILLER, WINSTON, and FISHER (8) revealed that the common green mold of citrus fruits, P. digitatum, produces a physiologically active emanation whose effects on plant tissue are the same as those caused by ethylene gas. It was shown by the latter authors and by BIALE and SHEPHERD (3) that this fungus produces this emanation whether grown on it...
متن کاملWhy do food and drink smell like earth?
Fungi have long been associated with earthy odours. One of the main contributors to this odour is geosmin, a sesquiterpenoid metabolite produced by soil living fungi. Some food commodities are liable to contamination by geosmin producing fungi. Under favourable environmental conditions the production of geosmin occurs. One of the producers of geosmin in fruits is Penicillium expansum which also...
