| molecular identification of species from the penicillium roqueforti group associated with spoiled animal feed. | 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 ribosomal internal transcribed spacer region. identities were confirmed with random amplified polymorphi ... | 2000 | 10742236 |
| differentiation of species from the penicillium roqueforti group by volatile metabolite profiling. | species from the penicillium roqueforti group were differentiated by volatile metabolite profiling primarily of sesquiterpenes. a total of 24 isolates from species p. roqueforti, penicillium carneum, and the recently described species penicillium paneum were inoculated on yeast extract sucrose agar. volatile metabolites were collected by diffusive sampling onto tubes containing tenax ta, overnight between the fifth and sixth days of incubation. volatiles were thermally desorbed and analyzed by g ... | 2005 | 15686424 |
| origin of (-)-geosmin on grapes: on the complementary action of two fungi, botrytis cinerea and penicillium expansum. | one of the consequences of rot on grapes is the development of volatile compounds giving fungal, mouldy or earthy odours. among these compounds, (-)-geosmin (trans-1,10-dimethyl-trans-9-decalol), a powerful aromatic compound with an earthy smell is a persistent defect in grape juice and wines made with at least partially rotten grapes. a microbiota analysis of rotten grapes containing (-)-geosmin was carried out on sites from four french regions from 1999 to 2002, to clarify the involvement in g ... | 2005 | 16096689 |
| the sequence of the isoepoxydon dehydrogenase gene of the patulin biosynthetic pathway in penicillium species. | interest in species of the genus penicillium is related to their ability to produce the mycotoxin patulin and to cause spoilage of fruit products worldwide. the sequence of the isoepoxydon dehydrogenase (idh) gene, a gene in the patulin biosynthetic pathway, was determined for 28 strains representing 12 different penicillium species known to produce the mycotoxin patulin. isolates of penicillium carneum, penicillium clavigerum, penicillium concentricum, penicillium coprobium, penicillium dipodom ... | 2007 | 17043910 |
| hydrolysate from a mixture of legume flours with antifungal activity as an ingredient for prolonging the shelf-life of wheat bread. | aiming at identifying antifungal compounds from plant matrices to be used as ingredients in the bakery industry, a water/salt-soluble extract (wse) was produced from a legume enzyme hydrolysate, consisting of a mixture of pea, lentil, and faba bean flours, and assayed towards penicillium roqueforti dppmaf1. agar diffusion assays allowed the selection of the optimal processing conditions for hydrolysis. as shown by hyphal radial growth rate, the inhibition was observed towards several fungi, incl ... | 2017 | 28213038 |
