| a preliminary survey of cycloheximide-resistant airborne fungi in turin, italy. | numbers and type of the cycloheximide-resistant part of the aerially transmitted mycoflora of turin were studied. samples from three areas characterized by differing human usage were taken in the first week of march. during each sampling, 12 m3 of air were aspirated, using an one-stage volumetric sieve sampler. fifty-two mesophilic species and eight thermotolerant were isolated. propagule load varied from 2.92 to 120.31 cfu m-3. the following species appear not to have been reported previously f ... | 1993 | 8247094 |
| germination and adhesion of fungal conidia on polycarbonate membranes and on apple fruit exposed to mycoactive acetate esters. | the adhesion and germination of conidia of nine fungal species were assessed on polycarbonate membranes or on the skin of apple fruit in sealed glass bottles injected or not injected with acetate esters. adhesion was determined after dislodging conidia from surfaces using a sonication probe. adhesion and germination of conidia of aspergillus flavus, aspergillus fumigatus, aspergillus niger, penicillium citrinum, penicillium claviforme, or trichoderma sp. on membranes after 48 h were not increase ... | 2003 | 12718401 |
| production of sordarin and related metabolites by the coprophilous fungus podospora pleiospora in submerged culture and in its natural substrate. | rabbit pellets collected from the field were colonized by podospora pleiospora at the exclusion of other coprophilous fungi, suggesting antibiosis. in liquid culture, p. pleiospora produced sordarin (1); sordarin b (2), a new compound in which sordarose is replaced by rhamnose; hydroxysordarin (3); and sordaricin (4). the major compounds 1 and 2 exhibited minimum inhibitory concentrations of 0.5-2.5 microg ml(-1) against the yeasts nematospora coryli and sporobolomyces roseus, but showed little ... | 2005 | 16018317 |
| protein splicing of prp8 mini-inteins from species of the genus penicillium. | inteins are protein-intervening sequences found inside the coding region of different host proteins and are translated in-frame with them. they can self-excise through protein splicing, which ligates the host protein flanks with a peptide bond. in this study, four different species of the genus penicillium were investigated for the presence of inteins inside the conserved splicing-factor protein prp8. we identified 157 to 162 amino acid in-frame insertions in the prp8 protein of penicillium chry ... | 2006 | 16544141 |
| 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 |

| feeding patterns of tyrophagus putrescentiae (sarcoptiformes: acaridae) indicate that mycophagy is not a single and homogeneous category of nutritional biology. | mycophagy should not be considered as a single and homogeneous category of nutritional biology due to the specific symbiotic chitinolytic bacteria associated with mites and fungi. to test interaction among mites, fungi, and chitinolytic bacteria, experiments were conducted on the model species tyrophagus putrescentiae (schrank). mucor sp, alternaria alternata, penicillium claviforme, p. griseofulvum, and verticillium sp. were plated onto malt agar and offered to t. putrescentiae in the laborator ... | 2016 | 27638952 |
| antifungal activity and identification of lactobacilli, isolated from traditional dairy product "katak". | filamentous moulds are the main spoilage microorganisms, responsible for significant economic losses and several healthy risks in human food chain. the lactic acid bacteria (lab), especially lactobacilli could be a natural antagonist of these dangerous organisms. in bulgaria, a very limited data exists on the antifungal activity of lab microbiota of fermented dairy products. in the present study, four active strains were isolated from traditional fermented curd/yogurt-like product "katak", produ ... | 2014 | 24887637 |
| antifungal activity of silver ion on ultrastructure and production of aflatoxin b1 and patulin by two mycotoxigenic strains, aspergillus flavus oc1 and penicillium vulpinum cm1. | the antifungal activity of silver ion from silver nitrate solution was tested against two pathogenic and toxigenic fungal strains. the first was aspergillus flavus oc1, a clinical aflatoxigenic strain that causes fungal keratitis and the second was penicillium vulpinum cm1, a maize-pathogenic strain that is positive for patulin (pat) producing ability. | 2014 | 24746717 |
| manganese-mediated morphogenesis in penicillium claviforme and penicillium clavigerum. | the colonial morphology and growth of penicillium claviforme and p. clavigerum in manganese-deficient, defined medium, were examined with and without manganese supplementation. in unsupplemented medium rendered free of manganese through treatment with a chelating resin, p. claviforme grew but did not produce coremia. similar results were obtained for p. clavigerum on media devoid of added manganese. however, when these media were supplemented with optimal concentrations of manganese both fungi p ... | 1977 | 837256 |

| detection of virus-like particles in the coremia of penicillium claviforme. | a double-stranded ribonucleic acid (dsrna) was isolated from coremial extracts of wild type p. claviforme, by methylated-albumin kieselguhr chromatography. differential centrifugations of the coremial extracts from wt and sh mutant strains yielded two classes of virus-like particles (vlp), of dimensions 25-30 nm, and 50-70 nm. the possible ecological significance of fungal viruses is discussed. | 1975 | 1203766 |
| regulation of coremium morphogenesis in penicillium claviforme. | coremia of penicillium claviforme develop in three stages; primordium formation, elongation, and sporulation. primordium formation was induced by external nutrients, while starvation initiated the differentiation of primordia into coremia with sporeheads. there is strong evidence that external nutrients are not taken up during this differentiation. continued sporulation by mature coremia again required an external nutrient supply. | 1975 | 1141857 |
