| [evolution of the microbiological parameters of cured ham]. | the main microbiological and physico-chemical parameters in dry-salted ham previously selected were determined along the elaboration process. all determinations were performed at 2 levels: surface and internal. all bacterial groups showed a similar behaviour, increasing along the first stages up to the third month of drying, then decreasing to numbers similar to the initial ones. only the halotolerants maintained fairly high numbers during last stages. some groups were almost absent at internal ... | 1993 | 8484910 |
| detection of volatile metabolites of moulds isolated from a contaminated library. | the principal fungal species isolated from a contaminated library environment were tested for their microbial volatile organic compound (mvoc) production ability. aspergillus creber, a. penicillioides, cladosporium cladosporioides, eurotium chevalieri, e. halophilicum, penicillium brevicompactum and p. chrysogenum were cultivated on suitable culture media inside sample bottles specifically designed and created for direct mvoc injection to a gc-ms instrument. the fungal emissions were monitored o ... | 2016 | 27392938 |
| water-, ph- and temperature relations of germination for the extreme xerophiles xeromyces bisporus (frr 0025), aspergillus penicillioides (jh06thj) and eurotium halophilicum (frr 2471). | water activity, temperature and ph are determinants for biotic activity of cellular systems, biosphere function and, indeed, for all life processes. this study was carried out at high concentrations of glycerol, which concurrently reduces water activity and acts as a stress protectant, to characterize the biophysical capabilities of the most extremely xerophilic organisms known. these were the fungal xerophiles: xeromyces bisporus (frr 0025), aspergillus penicillioides (jh06thj) and eurotium hal ... | 2017 | 27562192 |
| glycerol enhances fungal germination at the water-activity limit for life. | for the most-extreme fungal xerophiles, metabolic activity and cell division typically halts between 0.700 and 0.640 water activity (approximately 70.0-64.0% relative humidity). here, we investigate whether glycerol can enhance xerophile germination under acute water-activity regimes, using an experimental system which represents the biophysical limit of earth's biosphere. spores from a variety of species, including aspergillus penicillioides, eurotium halophilicum, xerochrysium xerophilum (form ... | 2017 | 27631633 |
| aspergillus penicilloides and eurotium halophilicum in association with house-dust mites. | aspergillus penicilloides speg., eurotium halophilicum christensen et al. and other xerophilic fungi were isolated from house dust. the isolates of e. halophilicum are described and compared with the type strain of this species. a. penicilloides appeared to be rather common. the species concept of this species is broadened to accomodate some variable forms with different colony characters and conidophore structures. the role of both species is discussed in connection with house-dust mites, house ... | 1978 | 714145 |
| amid the possible causes of a very famous foxing: molecular and microscopic insight into leonardo da vinci's self-portrait. | leonardo da vinci's self-portrait is affected by foxing spots. the portrait has no fungal or bacterial infections in place, but is contaminated with airborne spores and fungal material that could play a role in its disfigurement. the knowledge of the nature of the stains is of great concern because future conservation treatments should be derived from scientific investigations. the lack of reliable scientific data, due to the non-culturability of the microorganisms inhabiting the portrait, promp ... | 2015 | 26111623 |
